パナマ市 12月の天気

Regulars describe a real hinge inside this month: early December still carries the rainy season's high humidity, dropping mid-month as the shift toward dry season gets underway, with hours-long showers giving way to more sunny, beautiful days as the month closes. Our row averages across that transition at 31.2C reading as 36C at 85.2 percent humidity, with 86.3mm of rain across 18.3 days - a lot of days, each contributing relatively little. Locals call January through March their 'summer,' the drier season proper, though regulars warn it turns blistering and windy by March. Late December into January is their consensus for the driest window. The sea holds 29.1C. The record: 10 hours of sun, a 14.2 kph wind and AQI 34.

Regulars describe this as the final stretch of the dry season, hot and sunny the norm through most of the month, though the odds of rain climb noticeably by the back half as the wetter season approaches. Our row backs that hot, increasingly wet read, 32.5C reading as a brutal 38C, over 25.1C nights, with 94.3mm of rain across 14.7 days and humidity at 80 percent. Regulars are consistent humidity itself climbs alongside the rain risk, a real factor in how the heat feels compared with the drier stretch earlier in the season. This remains a genuinely hot month regardless of which half a trip lands in, sun protection and steady hydration the standard advice throughout. The sea sits at a warm 27.8C. The record: 10.4 hours of sun, a 14.2 kph wind and AQI 48.

Panama-forum threads on June weather (Panama City specifically among the destinations discussed) describe a reliable daily rhythm: a drenching downpour most afternoons, thirty minutes to an hour of genuinely heavy rain that floods the streets briefly before clearing, followed by sun again. The reverse pattern shows up too - a rainy morning often clears into a sunny afternoon. Regulars call June a favorite month since the tourist season has wound down, crowds thinner and prices lower than the December-through-April peak. The calmer, greener landscape that comes with the rains is a real visual upside for anyone touring the rainforest or historic sites. Daytime temperatures stay warm and humid throughout, the heat a more constant feature than any single rain event. The record: 30.2C days feeling like a punishing 36C, 25C nights, a notably high 278mm across 29.6 days, 89 percent humidity, a 30.2C sea and 7.6 hours of sun.

January opens what Panamanians call summer - the January to March dry season - and regulars pick it over the months that follow for a specific reason: it is early enough that the grass and trees are still green and the hot dry winds have not really started. Expect it may still rain, more in the mountains and at night than over the city, where an afternoon shower either comes or does not; our row's 29.9mm across 6.2 days is that. What the dry season removes is the rain's cooling, so the heat stands up on its own: 31.6C over a 24.2C night at 80 percent humidity reads as 36C by day and 28C after dark. Fewer visitors now than in February, too. The record: 10.6 hours of sun, a 16.4 kph wind, a 28.1C sea and AQI 38.

March is the far end of what Panamanians call verano, and the forum describes it in a way brochures do not: the sun is at its most punishing, the wind is constant, the grass has gone brown and there are fewer flowers than at any other time of year. January to March are the least wet months, but regulars are careful to add that this is still the tropics - a 15 or 20 minute shower can appear on any day, and the humidity does not leave, least of all in the city. It is also high season, with February and March the busiest and priciest stretch for foreign visitors. The record: 32.8C days that feel like 37C, 24.4C nights, 3.5 precipitation days, humidity 75 percent, 10.9 hours of sun, a 26.9C sea.
