Best Time to Visit Costa Rica (2026)- Month-by-Month Weather, Costs & Activities

Last updated: April 2026. Written for travelers planning trips in 2026 and beyond.

There is no single universally “best” time to visit Costa Rica — but there is a perfect time for your goals. Whether you want guaranteed sunshine, the cheapest hotels, prime wildlife encounters, or the biggest surf, the answer changes completely. This guide breaks it all down by month, season, region, and travel style so you can book with confidence.

Costa Rica’s Two Seasons: The Foundation You Need to Understand

Costa Rica operates on two seasons driven by the Pacific coast’s weather patterns. The dry season (locally called verano, or summer) runs from December through April. Expect clear blue skies, hot temperatures in the low 30s Celsius (mid-80s°F), and minimal rainfall on the Pacific side. This is peak tourist season — popular, but for good reason.

The green season (also called the rainy season or invierno) runs from May through November. It does not mean it rains all day. In reality, most green season days begin with glorious sunshine, with heavy refreshing showers rolling in during the late afternoon. The forests explode into electric green, waterfalls run at full power, and you’ll often have beaches almost to yourself.

One critical fact most travel guides gloss over: the Caribbean coast follows a completely opposite weather pattern. When the Pacific is at its wettest in September and October, the Caribbean coast (Puerto Viejo, Tortuguero) often enjoys its driest, sunniest weather. This single insight can unlock a fantastic budget trip.

Month-by-Month Breakdown: When to Go and Why

January — Peak Dry Season, High Demand

January is one of the most popular months to visit Costa Rica, and for good reason. The dry season is fully established on the Pacific coast, temperatures hover around 28–33°C (82–91°F) on the coast, and the forests are still green from the previous rains. Wildlife is active and easy to spot — sloths, monkeys, and tropical birds are abundant.

The downside is cost. January is expensive. Hotels in Tamarindo, Manuel Antonio, and La Fortuna book out weeks in advance. Expect to pay 40–60% more than you would in May. Book everything at least 3 months ahead.

Best for: First-time visitors, beach lovers, families with school schedules

February — The Sweet Spot of Dry Season

February is widely considered one of the best months to visit Costa Rica overall. The weather is superb on the Pacific and Central Valley, crowds are slightly lower than January (post-holiday), and you get the full dry season experience without paying Christmas-week prices.

The Guanacaste region (Tamarindo, Playa Flamingo, Nosara) is bone-dry and stunning. The Osa Peninsula in the south is also excellent in February, with prime conditions for whale shark sightings and outstanding biodiversity at Corcovado National Park.

Best for: Couples, honeymoons, first-timers wanting perfect weather

March — Hot, Dry, Busy Around Easter

March is still dry season, but be very aware of Semana Santa (Holy Week, which falls in late March or early April in 2026). This is when Costa Rica itself goes on vacation. Hotels triple in price, roads become gridlocked, and national parks hit maximum capacity. If traveling in March, either go in the first two weeks or book 4–6 months in advance.

Late March also sees the hottest temperatures of the year in Guanacaste, sometimes reaching 37°C (99°F). The rivers in the highlands can drop too low for white-water rafting.

Best for: Travelers who book early; avoid if you hate crowds

April — Transition Month with Great Value Late in the Month

Early April is still packed due to Easter holidays. But from mid-April onward, crowds thin dramatically and prices begin to drop. The very end of April is one of the most underrated times to visit — weather is still largely dry, the tourist rush has gone, and you can walk into hotels that were sold out two weeks prior.

Best for: Budget-conscious travelers who can go in late April; great for experienced travelers who know to avoid the early rush

May — Green Season Begins, Prices Drop Sharply

May marks the start of the green season on the Pacific coast, and with it, a significant shift in atmosphere. Hotel rates drop by 30–50% overnight. Crowds evaporate. The landscape transitions from dusty brown to vivid green within days of the first rains.

Rain is mostly afternoon showers at this point — mornings remain sunny and perfect for hiking, zip-lining, or visiting national parks. May is an excellent month for budget travelers and nature lovers.

Best for: Budget travelers, nature photographers, solo travelers

June — One of the Most Underrated Months

June is a hidden gem. The rains have settled into a pleasant rhythm of morning sunshine and afternoon showers. Prices remain low, crowds are thin, and the natural scenery is at its most dramatic — waterfalls are thundering, rivers are running, and wildlife is hyperactive.

Whale watching begins to pick up on the Pacific coast around Uvita and the Osa Peninsula, as southern hemisphere humpback whales begin arriving.

Best for: Budget travelers, wildlife enthusiasts, those seeking a quieter experience

July — The Veranillo: Costa Rica’s Secret Mini Dry Season

July brings a fascinating weather phenomenon called the veranillo, or “little summer.” For two to four weeks (typically mid-July to early August), the rains pause across much of the Pacific coast. You get dry-season-quality weather at green-season prices. This is the single best value window of the entire year for many experienced travelers.

Surf picks up significantly on the Pacific coast in July — waves are larger and more consistent, making it a great month for intermediate and advanced surfers. Wildlife is also exceptional: turtle nesting at Tortuguero (Caribbean) peaks, and humpback whale sightings near Uvita are at their best.

Best for: Experienced travelers seeking value, surfers, wildlife watchers — overall the top recommendation for 2026

August — Wildlife Peak, Great Caribbean Weather

August is spectacular for wildlife on both coasts. On the Pacific, humpback whales from the southern hemisphere are abundant near Ballena Marine National Park in Uvita — August and September are peak whale-watching months. Green sea turtles are actively nesting at Tortuguero on the Caribbean coast.

The veranillo may extend into early August, but rains return in full on the Pacific side by mid-month. The Caribbean coast, however, enjoys some of its best weather of the year.

Best for: Wildlife lovers, whale watchers, surfers, Caribbean-side visitors

September — Wettest Pacific, Best Caribbean, Absolute Lowest Prices

September is the wettest month on the Pacific coast and sees the lowest tourist numbers of the year. If you’re set on the Pacific, this is challenging — flooding is possible in lowland areas, and some rural lodges close. However, prices hit their annual floor, and you can find luxury eco-lodges at bargain rates.

The real play in September is the Caribbean coast. Puerto Viejo, Tortuguero, and Cahuita experience their driest, sunniest conditions of the entire year in September and October. Combine this with rock-bottom Pacific prices and you can stay cheaply in San José or the Central Valley, then travel to the Caribbean for stunning weather.

Best for: Experienced budget travelers, Caribbean coast visitors, those comfortable with rain on the Pacific

October — Still Wet Pacific, Still Gorgeous Caribbean

Similar to September, October sees heavy rainfall on the Pacific coast, particularly in the Osa Peninsula and southern zones. However, the rain begins easing up by late October. The Caribbean remains excellent. Prices are at their lowest, and national parks are at their least crowded — you might have Corcovado nearly to yourself.

Not recommended for: First-time visitors planning a Pacific coast beach trip, those uncomfortable with heavy rain

November — The Best Transition Month

November is arguably the most underappreciated month in Costa Rica. By mid-November, the rains on the Pacific coast have significantly decreased. The landscape remains lush and green from the wet season but the weather is rapidly improving. Prices have not yet risen to peak season levels, and crowds are still thin.

The dry season officially returns to most areas by late November, and wildlife is extraordinary — turtle nesting continues, migratory birds begin arriving from North America, and humpback whales (now from the northern hemisphere) can be spotted along the Pacific coast from December onward.

Best for: Value hunters who want near-dry-season weather at green-season prices

December — Dry Season Returns, Prices Rise Fast

The dry season reestablishes itself across Costa Rica in December, and with it, the crowds and prices return. The first two weeks of December are actually a wonderful sweet spot — weather is excellent, but the Christmas rush hasn’t fully arrived. From December 20 onward, Costa Rica enters its most expensive and most crowded window of the year.

Best for: Holiday travelers (book 4–6 months ahead), early December visitors seeking a value window before peak

Practical Tips That Make a Real Difference

Book Semana Santa 4–6 months ahead or avoid it entirely. The entire country shuts down for a beach vacation during Easter week. Prices triple. Traffic is intense. Unless you specifically want to experience this cultural event, plan around it.

Get a 4×4 vehicle for green season. Many of Costa Rica’s best destinations — Corcovado, remote Caribbean beaches, cloud forest lodges — require river crossings and dirt roads that become impassable in a standard sedan during heavy rains.

Pack a lightweight rain jacket year-round. Even in dry season, the rainforests do occasionally receive afternoon showers. A packable rain jacket weighs almost nothing and saves the day repeatedly.

Book morning excursions. In the green season especially, mornings are almost always clear. Tours that start before 8am — hiking, wildlife watching, zip-lining — are far less likely to be rained out.
