One of the most common questions we get is "When should I visit La Fortuna?" The honest answer: any time of year is great, but each season offers different advantages. This guide breaks down the weather, wildlife activity, crowd levels, and pricing by month so you can choose the perfect time for your trip.

Dry Season (December–April)

The dry season offers sunny mornings, easier trail conditions, and the best chance to see Arenal Volcano without cloud cover. This is peak tourist season, so book tours 2–3 weeks in advance. Wildlife is concentrated near water sources, making sightings easier. Temperatures average 28–33°C (82–91°F).

Green Season (May–November)

The "rainy" season is actually the best time for nature lovers. Rain usually falls in the afternoon, leaving mornings clear for tours. The rainforest is at its lushest, waterfalls are at their most powerful, and birdwatching diversity peaks with migratory species arriving in October. Prices are 15–25% lower and crowds are minimal.

Best Months for Wildlife

February–April: nesting season for many bird species. May–June: frog and amphibian activity peaks. October–March: migratory birds arrive (warblers, tanagers, raptors). Year-round: sloths, toucans, monkeys, and nocturnal wildlife are active regardless of season.

Month-by-Month Summary

Jan–Mar: Dry, sunny, peak season, higher prices. Apr: Transitional, fewer crowds, great deals. May–Jun: Green season begins, lush landscapes, excellent frogs. Jul–Aug: Mini dry season ("veranillo"), good balance. Sep–Oct: Wettest months, best bird migration, lowest prices. Nov: Rain easing, still green, great value. Dec: Dry season starts, holiday crowds return.

Frequently Asked Questions

What is the actual best month to visit La Fortuna?

For clear Arenal Volcano views and easy trails, February and March are the best months. For wildlife, photography and value, choose May, June or November — rain usually falls in the afternoon, so morning tours run normally.

Is the rainy season a bad time for tours in Arenal?

No. In the green season (May–November) mornings are usually clear and the rain arrives after 1–2 PM. We simply schedule wildlife walks, hanging bridges and waterfall visits early, and keep hot springs for the afternoon.

When is the best time for birdwatching in La Fortuna?

October through March, when North American migrants join the resident species. Nesting activity for resident birds peaks between February and April. Early morning departures (5:30–6:00 AM) are essential year-round.

How far in advance should I book tours in La Fortuna?

In high season (December–April and July) book 2–3 weeks ahead, especially for private guides and night tours. In green season, 3–7 days is usually enough. Our booking cutoff is 12 hours before a guided tour.

Will I see the Arenal Volcano summit?

The summit is clearest in the early morning, especially January–April. Even in wet months, the volcano usually clears for a while at sunrise, which is why our Arenal 1968 and hanging bridges tours start early.

Are tour prices different by season?

Our published tour prices stay the same year-round. What changes is availability: green season means smaller groups, easier private upgrades and more flexible scheduling.
