4月的圣何塞旅人笔记
来自附近哈科區的笔记（相距 69 公里）
圣何塞还没有自己在4月的笔记——下面这些是关于哈科區的，离得够近，季节相同。
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.
圣何塞的其他月份
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.
