Best Time to Visit Manuel Antonio (Weather, Crowds & Wildlife)
Manuel Antonio is open all year, but not every month feels the same. With a little planning you can pick the weather, smaller crowds, and better wildlife. Here's when to go.
Dry season vs. green season
Costa Rica has two main periods. The dry season (December–April) brings sun, great beaches, and less rain, but also the most visitors and tickets sell out fast. The green season (May–November) has afternoon showers, a lusher forest, and far fewer people, with lower lodging prices.
Weather month by month
- Dec–Apr: clear days, peak crowds. Book tickets weeks ahead.
- May–Jul: soft afternoon rain, explosive nature, short lines.
- Aug–Oct: the "little summer" can bring sunny weeks; a good balance.
- Nov: transition; the forest is at its greenest.
Best time of day
Early morning is unbeatable: animals are active, it's cooler, and the crowds haven't arrived. An early guided tour makes the most of that window better than a midday walk.
How to dodge the crowds
The park opens early and caps daily capacity. Arrive at opening, buy your SINAC tickets in advance, and avoid weekends and holidays. If you want calm, the green season is your friend.
Wildlife by season
Sloths and monkeys are seen year-round, but birds and amphibians (like the red-eyed tree frog) boom in the green season. For planning sightings, see our park wildlife guide and our wildlife-spotting secrets.
Bottom line
There's no bad time, only a best one for what you want. Whether sun or rainforest, our National Park tour includes tickets and a guide who maximizes what you see. Pack with our essential checklist and you're set.
