Været i Puerto Viejo (Puerto Viejo de Talamanca) i mai

Bocas del Toro-forum threads on May and June weather are direct that there's no month that reliably avoids rain here, showers a real possibility on the large majority of days regardless of which month is picked. Posters are consistent that getting rained on at some point during a trip should simply be expected rather than treated as bad luck, and the standing packing advice is a proper umbrella over a rain jacket, since the humidity makes fully sealed rain gear miserable to wear for long. The pattern that does hold, per regulars, is real sunny stretches between the showers rather than an all-day washout, so a rained-on morning doesn't necessarily mean a lost afternoon. Warm, muggy air is the constant regardless of rain, described as the more persistent discomfort than any individual shower. The record: 28.6C days feeling like a sticky 35C, 24.4C nights, a notably high 198mm across 25.4 days, 86 percent humidity, a 30.5C sea and 8.6 hours of sun.

Puerto Viejo's forum consistently rates August as better than the genuinely wet June-July stretch on the Caribbean coast, with the back half of the month described as noticeably improving as September - reportedly the driest, sunniest month here - approaches. That framing is relative, though: some rain most days is still the norm this time of year, and posters were honest that Caribbean-side weather stays genuinely unpredictable regardless of the calendar. Hot and humid is the constant, with the real variable being how much of each day gets interrupted by a shower.

Forum posters describe February as genuinely variable here - some visitors get a good run of sunny days mixed with a few cloudy, showery ones, while others land mostly sunny and dry throughout their stay, with no reliable way to predict which in advance. Posters are consistent that the Caribbean side of Costa Rica, where Puerto Viejo sits, gets real rain year-round unlike the more clearly seasonal Pacific coast, with local experience suggesting roughly 65% of rain falls at night and most daytime rain is a short shower rather than an all-day event. Posters generally rate the destination higher for wildlife and rainforest activities than for guaranteed beach-lounging weather, given the real chance of a rainier-than-hoped stretch even in the relatively better dry season.
