Traveller notes on Manuel Antonio in April
Notes from nearby Jacó (57 km away)
Manuel Antonio doesn't have its own notes for April yet — these are about Jacó, close enough to share the season.
The consensus on April for this coast is that it is transitional - not the driest, nowhere near the wettest - and our row proves it exactly: 242.9mm here against 581.8mm in May and 829.3mm in October. What the numbers cannot show is the timing, and the board supplies it: rain on the central Pacific coast comes in the afternoon or overnight, it is warm rain, and the weather apps that promise rain all day every day are wrong about the shape while right about the odds. Our 27.6 rainy days is that same statement. Pack fast-drying clothes rather than cotton, and something light to keep it off. Heat holds at 29.1C reading as 36C, with a 30.3C sea. The record: humidity 83 percent, 10.4 hours of sun and AQI 36.
Other months in Manuel Antonio
Manuel Antonio's forum describes a fairly consistent August rhythm: clear, pleasant mornings, thunder rolling in over the mountains by early-to-mid afternoon, and rain arriving anywhere from 4 to 6pm that can continue into the night or clear up fast - though posters admitted the exact timing varies day to day and forecasts aren't reliable. The first half of the month tends to be somewhat less rainy than the back half. It's hot, humid and genuinely one of the wettest stretches of the year here, but the payoff repeated by multiple visitors is how lush and green everything gets - worth planning mornings for outdoor time and afternoons for a siesta.
Forum posters name February as the hottest month of the year here - typically 90-97F in the jungle, occasionally hotter right on the beach - and call it peak season for good reason, with humidity staying high (70%+) under blue skies dotted with big white clouds. Posters describe February as Manuel Antonio's driest month by local standards, though this is still a rainforest climate with real, near-daily rain even at its driest - the honest framing is 'least wet' rather than genuinely dry, since afternoon showers remain a common feature even in February, just shorter and less frequent than the region's true wet season (May-November). Posters are also emphatic that online weather forecasts for this area are essentially useless - conditions shift too fast and locally to trust anything beyond the broad seasonal pattern.
