Best Time to Visit Costa Rica: A Seasonal and Month by Month Guide

Updated for 2026

Quick Answer

The best time to visit Costa Rica is during the dry season, from December to April, when skies stay clear and roads are easiest to drive. Budget minded travelers and photographers often prefer May, June, or November, the green season's shoulder months, when rain is light, crowds thin out, and hotel and car rental rates drop.

Costa Rica does not really have a wrong time to visit. What changes from month to month is the trade off between sunshine, cost, crowds, and how easy the roads are to drive. The dry season, from December through April, delivers the sunniest beach days and the most predictable driving conditions. The green season, from May through November, trades some afternoon rain for lower prices, quieter trails, and a rainforest that looks genuinely alive.

This guide breaks Costa Rica's climate down season by season and month by month, adds the regional differences that most travel articles skip, and answers the planning questions that come up most often among people booking a self drive trip: when rental rates are lowest, which coast stays dry when the other is soaked, and when a four wheel drive rental actually earns its cost.

Key Takeaways

• Dry season (December to April) brings the most sunshine, the best road conditions, and the highest prices.

• Green season (May to November) means lush scenery, thinner crowds, and rental rates that can drop by 30% to 40% compared to January or February.

• September and October are Costa Rica's rainiest months on the Pacific side, but the Caribbean coast often stays dry during those same weeks.

• Costa Rica welcomed 2,943,991 international arrivals in 2025, according to the Costa Rican Tourism Institute (ICT), with early 2026 running ahead of that pace.

• Whichever season you pick, a vehicle with real ground clearance matters more in Costa Rica than the calendar date.

When Is the Best Time to Visit Costa Rica? Seasonal Overview

Costa Rica has two seasons, not four: the dry season (also called the high season), running roughly December through April, and the green season (also called the rainy season), running May through November. The dry season delivers the most reliable sunshine and the highest prices. The green season delivers lower rates, fewer crowds, and mostly sunny mornings with afternoon showers rather than all day rain.

The Dry Season (December to April): Sunshine and Peak Season Pricing

If clear skies and beach days matter most, December through April is the best time to visit Costa Rica. Rain is minimal, humidity drops, and outdoor activities like hiking, zip lining, and volcano viewing run without weather delays. Guanacaste and the northern Pacific coast see the least rain of any region during these months.

Dry season is also peak season. Hotel rates and rental car prices climb, and popular routes toward Arenal, Monteverde, and Manuel Antonio get busy, especially around Christmas, New Year, and Easter week. Book accommodations and a car rental in Costa Rica at least a month or two ahead if you are traveling in January, February, or over a holiday week.

The Green Season (May to November): Lush Scenery and Lower Rates

The green season is when Costa Rica earns its reputation for biodiversity. Waterfalls run full, rivers rise, and the rainforest canopy turns a deeper shade of green, making Costa Rica's most scenic destinations especially rewarding to explore.

Rain typically falls in the afternoon, not all day, so mornings are usually clear enough for hikes, tours, and wildlife watching.

May, June, and November are the green season's best value windows. Rain is present but not constant, crowds are thin, and hotel and rental rates can undercut January prices by a wide margin. September and October bring the heaviest rain on the Pacific side, though the Caribbean coast often sees its driest weeks of the year at exactly this time, a detail many guides leave out.

Pro Tip

If you plan to drive during the green season, choose a vehicle with real ground clearance rather than a compact sedan. Rural and unpaved roads soften quickly after heavy rain, and river crossings that are easy in February can be impassable in September. Matching a suitable rental car to the season, not just the itinerary, is one of the most overlooked parts of Costa Rica trip planning.

Dry Season vs Green Season: The Costa Rica Season Fit Matrix

Choosing between Costa Rica's two seasons comes down to four factors: weather, cost, crowds, and road access. We call this comparison the Costa Rica Season Fit Matrix, a simple way to match your priorities to the right months instead of defaulting to whatever season everyone else books.

Costa Rica's Three Climate Zones: Why Region Matters More Than Month

Costa Rica's climate is not one climate. The country sits across the Pacific coast, the Caribbean coast, and the Central Valley highlands, and each behaves differently in the same week. Most travel guides describe the country as if a single dry and rainy season applies everywhere. It does not, and that gap is one of the most common sources of confusion for first time visitors.

Costa Rica climate zones by region

This is why the Caribbean coast is often the smartest pivot for travelers whose trip lands in September or October. While the Pacific side gets its heaviest rain of the year, destinations such as Puerto Viejo and Cahuita are usually enjoying their driest stretch.

Month by Month Guide to Costa Rica's Weather

Here is what to expect in Costa Rica month by month, including temperature ranges, festivals, wildlife activity, and a planning tip for each.

Costa Rica weather by month and rainfall patterns

January: Sunshine, Crowds, and Costa Rica's Biggest Festival

Is January a good time to visit Costa Rica? Yes, it is one of the two best months for guaranteed sunshine, though it is also peak season for both crowds and prices. Skies stay clear across the country, and the landscape is still green from the tail end of the previous rainy season.

• Temperature: 75°F to 86°F (24°C to 30°C)

• Notable event: The Palmares Festival runs January 15 to 26, 2026, drawing more than a million visitors to the town of Palmares for concerts, a horse parade, and carnival events.

• Wildlife: Humpback whales from the Alaska and California population begin arriving on the Pacific coast, alongside nesting olive ridley and leatherback sea turtles.

Tip: January books up fast, especially around the Palmares Festival. Plan your accommodation and travel arrangements at least four to six weeks ahead to avoid limited availability and higher prices.

February: Peak Dry Season and Prime Wildlife Viewing

February is one of the driest, sunniest months anywhere in Costa Rica, making it ideal for beach trips and wildlife spotting since thinner dry season vegetation makes animals easier to see.

• Temperature: 77°F to 88°F (25°C to 31°C)

• Notable event: The National Orchid Show takes place in San Jose in late February or early March.

• Wildlife: Peak nesting season for the resplendent quetzal begins in cloud forests such as Monteverde, and Pacific coast sea turtle nesting continues.

Tip: Head to Tamarindo or the wider Guanacaste coast for the driest beach weather in the country this month.

March: Warm Days and National Park Season

March keeps the dry season streak going with warm, mostly rainfree days, making it a strong month for exploring national parks before the April heat peaks.

• Temperature: 77°F to 91°F (25°C to 33°C)

• Notable event: The National Orchid Show sometimes falls in early March instead of late February.

• Wildlife: Sea turtle nesting continues on both coasts, and dry forest wildlife around Guanacaste is highly visible.

Tip: Pack sturdy footwear. Trails around Arenal Volcano and Monteverde are dry but can be rocky and uneven this time of year.

April: The Hottest Month and the End of Dry Season

Is April hot in Costa Rica? Yes, April is typically the country's hottest month, with dry vegetation, low rivers, and daytime highs that regularly push into the low 90s Fahrenheit before the rains return.

• Temperature: 78°F to 91°F (26°C to 33°C)

• Notable event: Semana Santa (Holy Week) falls in April in most years, bringing major domestic travel and celebrations nationwide.

• Wildlife: Wildlife gathers near shrinking water sources, which can make animals easier to spot despite the heat.

Tip: If your trip lands during Semana Santa, book your rental car and lodging well in advance. Many businesses close for part of the week, and roads near beach towns get congested.

May: The Start of the Green Season

Is May a good time to visit Costa Rica? Yes, May marks the start of the green season with a gentle transition, sunny mornings, and lower prices, while still avoiding the heaviest rains that arrive later in the year.

• Temperature: 75°F to 87°F (24°C to 31°C)

• Wildlife: Leatherback and hawksbill sea turtles continue nesting on the Caribbean coast.

Tip: Rain typically arrives by early afternoon, so plan hikes and outdoor tours for the morning.

June: Lush Landscapes and Family Travel

June brings consistent rainfall and the greenest scenery of the year, along with a small bump in visitors as school holidays begin in North America and Europe.

• Temperature: 75°F to 86°F (24°C to 30°C)

• Wildlife: Tortuguero National Park enters its main green turtle nesting window, and the Caribbean coast tends to run drier than the Pacific side this month.

Tip: A rental car still makes sense in June, but allows extra travel time on rural routes because afternoon rain can slow traffic and make some unpaved roads more challenging.

July: Veranillo, or Costa Rica's Mid Year Dry Spell

Does it rain less in July in Costa Rica? Often yes. Many years bring a short dry stretch locals call veranillo, or little summer, with sunnier days breaking up the green season rain.

• Temperature: 75°F to 86°F (24°C to 30°C)

• Wildlife: The Antarctic humpback whale population begins arriving in the Golfo Dulce area, a separate migration from the one seen in January and February.

Tip: Veranillo timing shifts from year to year, so treat it as a likely bonus rather than a guarantee when planning outdoor days.

August: Whale Watching and Family Adventures

August remains part of the green season, but rain mostly falls late in the day, leaving mornings open for adventure activities and marine wildlife tours.

• Temperature: 75°F to 86°F (24°C to 30°C)

• Wildlife: Humpback whale watching peaks near Uvita and Marino Ballena National Park, and Tortuguero's turtle nesting continues.

Tip: Family travel is common in August, so book popular tours a few days ahead even though hotel rates stay well below dry season peaks.

September: The Rainiest Month on the Pacific, and the Best Value of the Year

Is September a bad time to visit Costa Rica? Not if you plan around it. September brings the heaviest Pacific coast rain of the year, but it is also the cheapest month to travel, and the Caribbean coast is usually enjoying its driest weather at the same time.

• Temperature: 73°F to 84°F (23°C to 29°C)

• Wildlife: This is prime time for whale watching near Uvita and for storm free wildlife viewing on the Caribbean side.

Tip: Consider basing part of your trip on the Caribbean coast around Puerto Viejo or Cahuita, where September often delivers sunnier days than the Pacific.

October: Caribbean Sunshine While the Pacific Stays Wet

October continues September's pattern, heavy rain on the Pacific side, dry and sunny conditions on the Caribbean coast, plus Costa Rica's lowest prices of the year.

• Temperature: 73°F to 84°F (23°C to 29°C)

• Wildlife: Baby sea turtles hatch at Tortuguero National Park, and coffee harvest season begins in the Central Valley.

Tip: A rental car earns its keep in October since public transport options thin out and having your own vehicle makes it easy to relocate toward drier Caribbean weather if the Pacific side turns stormy.

November: The Bridge Month Between Rain and Sunshine

November is a transition month, rainfall tapers off through the second half, landscapes stay vividly green, and crowds are still thin before the December rush begins.

• Temperature: 74°F to 86°F (24°C to 30°C)

• Notable event: Culture Day and the Limon Festival take place on the Caribbean coast in mid October through early November, and coffee harvest festivities continue.

• Wildlife: Migratory birds arrive from North America, and sea turtle activity continues on the Pacific coast.

Tip: National parks such as Corcovado and the Osa Peninsula are excellent in November, with fewer visitors than the December to April peak.

December: The Return of Sunshine and Peak Season Pricing

December opens with fading rain and closes with the year's busiest, most expensive travel weeks, as the dry season and the Christmas and New Year holidays arrive together.

• Temperature: 75°F to 86°F (24°C to 30°C)

• Notable event: San Jose hosts the Festival of Lights in mid December, with illuminated floats and a parade through the capital.

• Wildlife: Alaska and California humpback whales begin returning to the Pacific coast, overlapping with the start of dry season sea turtle nesting.

Tip: Book your rental car and hotel two to three months ahead for travel over Christmas or New Year. Rates can climb 20% to 40% above the September low.

Costa Rica Weather by Month: Quick Reference Table

Best Time to Visit Costa Rica for Specific Interests

Your ideal travel window depends on what you came for. Here is the best time to visit Costa Rica by activity.

Wildlife Viewing

The best time to visit Costa Rica for wildlife viewing is the dry season, December through April, when thinner vegetation makes animals easier to spot. One detail most guides miss: Costa Rica sees two separate humpback whale migrations. The Alaska and California population passes through roughly December to March, while a second, Antarctic population arrives from around July to November. Combined, whales are visible off the Pacific coast for most of the year, just from two different directions.

Beaches and Surfing

Beach lovers chasing guaranteed sun should target December through April, especially Guanacaste and the northern Pacific coast. Surfers often prefer the green season instead. Bigger, more consistent swells build along the Pacific coast from May through November, with Santa Teresa, Tamarindo, and Pavones among the most popular breaks.

Hiking and National Parks

Dry season trails are firmer and easier underfoot, which makes December through April the most comfortable window for hiking around Arenal, Monteverde, and Corcovado. Hikers who prioritize solitude over dry footing often prefer May, June, or November, when trails are far less crowded.

Road Tripping and Self Drive Trips

Dry season driving is the most predictable, with firm roads and minimal risk of flooded river crossings. Green season self drive trips are still very doable, and many travelers prefer them for the lower rates, but they call for a vehicle suited to wet, sometimes unpaved roads. This is where knowing driving in Costa Rica conditions by season, rather than assuming they stay the same all year, makes the biggest difference.

Budget Travel

September is typically the cheapest month to visit Costa Rica. Hotel and rental car rates can fall 30% to 40% below January and February pricing, since it sits at the peak of the Pacific coast's rainy season and tourist volume drops accordingly.

Is There a Worst Time to Visit Costa Rica?

There is no single worst month to visit Costa Rica, but September and October on the Pacific coast come closest for travelers who want guaranteed sunshine. Rain is heaviest, some rural roads soften, and a handful of remote lodges close temporarily for maintenance. The fix is regional, not seasonal: shift part of your itinerary to the Caribbean coast, where September and October are typically the driest weeks of the year, or accept the trade for the lowest prices and thinnest crowds anywhere on the calendar.

Driving in Costa Rica by Season: What Changes When the Rains Arrive

Road conditions in Costa Rica shift more with the season than almost anywhere else in Central America. During the dry season, paved highways and most rural roads are firm and predictable. During the green season, unpaved roads soften, river crossings rise, and low clearance vehicles can struggle on routes into Monteverde, the Osa Peninsula, and parts of the Nicoya Peninsula.

Costa Rica requires every rental vehicle to carry mandatory third party liability coverage by law, a policy detail worth understanding before you sign a rental agreement, alongside any optional liability insurance coverage you choose to add.

If your itinerary includes rural national parks, mountain routes, or beach towns off the main highways, choosing a suitable rental car before you arrive saves time and stress compared to discovering the terrain is wrong for your vehicle once you are already on the road.

Costa Rica Hurricane Season and Storm Safety

Does Costa Rica get hurricanes? Rarely. Costa Rica sits far enough south that direct hurricane hits are uncommon, even though the wider Atlantic hurricane season runs June through November and peaks in September and October. Storms passing well offshore can still bring heavier than usual rain and stronger wind to the Caribbean coast during these months.

Travelers visiting in September or October should check the National Meteorological Institute (IMN) forecast a few days before road trips into rural areas, since heavy rain events can temporarily affect river crossings and unpaved roads even without a named storm.

When to Book Your Costa Rica Trip

Costa Rica tourism is growing again after a soft patch in 2024. The Costa Rican Tourism Institute (ICT) recorded 2,943,991 international arrivals in 2025, up slightly on the prior year, with 653,969 arrivals in just January and February 2026, a pace ahead of the same period the year before. Rising demand around the December through April dry season means earlier booking windows matter more than they did a few years ago.

• December to April (peak season): book flights, hotels, and your rental car six to eight weeks ahead, and three months ahead for Christmas, New Year, or Easter week.

• May, June, November (shoulder season): two to four weeks ahead is usually enough, with room to negotiate on rates.

• September and October (low season): last minute bookings are realistic, and this is when seasonal versus last minute car rental pricing tends to favor travelers the most.

Once your dates are set, book a reliable car rental in Costa Rica early to secure better vehicle availability during the dry season and choose a vehicle suited to your route and travel conditions, rather than settling for whatever is left.

Quick Summary

Dry season (December to April) means sun, firm roads, and peak prices.

Green season (May to November) means lower cost, lusher scenery, and a need for a higher clearance rental car.

September and October are the Pacific coast's rainiest months, but the Caribbean coast is often at its driest.

Two separate humpback whale migrations mean whale watching is possible for most of the year.

Book dry season travel six to eight weeks ahead; green season trips can often be booked closer to departure.

Best Time to Visit Costa Rica: FAQs

What is the best month to go to Costa Rica?

January and February are generally the best months, combining reliable sunshine, dry roads, and easy wildlife spotting. Expect peak season prices and crowds at popular parks and beaches during both months.

What is the cheapest month to visit Costa Rica?

September is usually the cheapest month. Hotel and rental car rates can run 30% to 40% below January levels, since it falls during the Pacific coast's heaviest rain.

Which side of Costa Rica is better, Pacific or Caribbean?

Neither is universally better. The Pacific coast has more beach towns, resorts, and dry season sunshine. The Caribbean coast is quieter, culturally distinct, and often driest exactly when the Pacific is wettest, in September and October.

Are there mosquitoes in Costa Rica?

Yes, especially in lowland and coastal areas during the green season (May to November), when standing water increases after rain. Insect repellent and long sleeves in the evening are standard precautions countrywide.

Do I need a four wheel drive rental car in Costa Rica?

Not always. Main highways and dry season routes are fine in a standard sedan or small SUV. A four wheel drive with real ground clearance matters most for green season travel and for rural routes into Monteverde, the Osa Peninsula, or the Nicoya Peninsula's back roads.

When do sea turtles nest in Costa Rica?

Nesting happens somewhere on the coast almost year round. Olive ridley and leatherback turtles nest on the Pacific coast mainly from July to December, while green and leatherback turtles nest on the Caribbean coast, especially at Tortuguero, from roughly March to October.

What is the best time to visit Costa Rica for surfing?

May through November brings the most consistent Pacific swells, with Santa Teresa, Tamarindo, and Pavones among the top spots. Dry season still offers surfable waves, just with less consistency.

Is Costa Rica crowded around Christmas and New Year?

Yes, late December is Costa Rica's busiest and most expensive travel window. Hotel rates commonly rise 20% to 40%, and popular routes toward Tamarindo, Manuel Antonio, and Arenal fill up. Book accommodations and a rental car two to three months ahead.
