Het weer in San José in juni

La Fortuna-forum threads on whether the wetter season is really that bad are consistent the answer is no, one poster direct nobody can reliably predict exactly when a shower hits, beyond March running noticeably calmer than the rest of the year. Regulars describe a typical June day as clear through the morning, with heavier activity building through afternoon and evening before clearing again, most operators running tours on a morning schedule to work around this pattern. Posters call waterfall visits and nature walks genuinely excellent in June, the surrounding rainforest at its greenest, with hotel and tour prices noticeably lower than peak season. A poncho and fast-drying clothing are standing advice regardless of forecast. Regulars call June entirely workable for a first-time visitor willing to plan mornings around outdoor activities. The record: 27.3C days feeling like a punishing 32C, 21.7C nights, an extraordinarily high 258mm across 29 days and 93 percent humidity.

Forum posters generally rate August as a good month to visit Costa Rica overall, describing a typical lowland or coastal day as sunny and hot in the morning with rain, sometimes heavy, moving in during the afternoon or evening - a pattern posters say leaves the landscape noticeably greener. San Jose itself, at over 1,100m elevation, runs noticeably milder than those hotter coastal descriptions, with comfortable daytime highs rather than genuine heat. Posters are direct that late August specifically can turn genuinely rainy, and while Pacific-slope rain is usually confined to afternoon and evening, posters emphasize there's no guarantee during rainy season. One visitor's second-half-of-August trip found mostly good weather, though posters are consistent that predicting exact conditions for specific dates isn't really possible. Posters generally rate August as workable and even good for a San José-area visit, rain gear recommended regardless.

February is deep in Costa Rica's dry season, and San José sits at altitude, so it runs cooler than the coasts — near 26°C by day, dropping to 17 at night. "Dry season" is the forum's own phrase and their own caveat: it does not mean it cannot rain, and eight wet days is the record's answer. Regulars pack an umbrella regardless. Two regional notes matter more than the capital's own weather: the Caribbean side is reliably rainier and cloudier than the Pacific in February, and Guanacaste gets serious wind this month while La Fortuna, Monteverde and Manuel Antonio generally do not.
