Best Time to Visit La Fortuna, Costa Rica: A Month-by-Month Guide
If you're planning a trip to Arenal Volcano, the single question that shapes everything else — your budget, your packing list, and even which tours you can book — is simple: when should you go? The short answer: the best time to visit La Fortuna is during the dry season, from mid-December to April, when skies are clearest and the volcano is most likely to be visible. But that's not the whole story, and depending on what you're after, another month might actually serve you better.
This guide breaks down La Fortuna's weather season by season and month by month, so you can time your trip around what matters most to you — clear volcano views, fewer crowds, lower prices, or lush, waterfall-fed rainforest.
Quick Answer: La Fortuna's Two Seasons
La Fortuna sits in Costa Rica's Northern Lowlands, one of the rainiest micro-climates in the country, so "dry season" here is relative — even in February you'll likely see a passing shower.
- Dry season (mid-December to April): Sunniest days, best volcano visibility, highest prices, busiest trails
- Green season (May to mid-December): Lower prices, thinner crowds, waterfalls at their fullest, afternoon rain is routine
Neither season is objectively "better" — it depends on whether you're chasing clear skies or good deals. Below, we break down each month so you can match the calendar to your priorities.
Dry Season in La Fortuna (December–April)
This is Costa Rica's high season, and for good reason. Mornings are typically clear and sunny, which matters more in La Fortuna than almost anywhere else in the country — Arenal Volcano is famously shy, and it's not unusual for it to hide behind clouds for days during the rainy months. Dry season gives you the best odds of an unobstructed volcano view.
What to expect:
- Daytime temps: 75–90°F (24–32°C)
- Rain: Occasional, usually brief afternoon showers
- Crowds: Heaviest at hotels, hot springs, and popular trails
- Prices: Peak-season rates on hotels and tours
Best for: First-time visitors, photographers wanting clear volcano shots, travelers combining La Fortuna with a beach stretch on the Pacific coast, anyone booking a Hanging Bridges rainforest walk who wants dry trails underfoot.
Trade-off: Book accommodations and tours 6–8 weeks ahead during December–April, especially around Christmas, New Year's, and Easter week (Semana Santa), when the entire region sells out.
Green Season in La Fortuna (May–November)
Don't let the word "rainy" scare you off. Costa Ricans call this the green season for a reason — this is when the rainforest is at its most vivid, waterfalls run at full force, and rivers have enough volume for whitewater rafting. Rain tends to fall in predictable afternoon bursts, leaving mornings free for hiking, ziplining, and wildlife viewing.
What to expect:
- Daytime temps: 73–86°F (23–30°C)
- Rain: Daily afternoon showers, heaviest September–November
- Crowds: Noticeably thinner, shorter lines at hot springs
- Prices: 20–40% lower on hotels; more tour availability
Best for: Budget-conscious travelers, waterfall chasers, anyone wanting a quieter, more personal experience with guides, travelers prioritizing lush jungle scenery over guaranteed volcano views.
Trade-off: Volcano visibility drops, and September–October can bring heavier, more persistent rain — worth planning around if seeing Arenal's cone is a must.

Chasing clear volcano views: January through March gives you the best odds of seeing Arenal's iconic cone without cloud cover. Pair a clear morning with the Arenal Volcano guide to plan your viewpoint stops.
Ziplining and canopy tours: Dry season trails are firmer underfoot, but La Fortuna's zipline circuits run rain or shine — the forest canopy shields most of the rain anyway. See the Zipline Adventure in La Fortuna for details.
Waterfalls and rivers: Green season, especially June through August, is when La Fortuna Waterfall and nearby rivers run fullest and most photogenic.
Hot springs: Genuinely year-round — geothermal water doesn't care about the calendar, and a soak feels even better after a rainy-season afternoon shower.
Wildlife and birdwatching: Green season's denser rainfall means more active wildlife and better birding, since food sources are abundant. Check what to do in Arenal for a full activity breakdown by interest.
Budget travel: September and October are La Fortuna's cheapest months for hotels and tours by a wide margin — if you can handle the rain, this is when your dollar goes furthest.
