December opens the summer here and the board argues about the humidity rather than the heat - some compare it to a New York July, others say it is nowhere near Miami. Our column takes the second side: 64 percent humidity with a dew point of 15.3C, so 28.3C reads as 30C rather than worse. The heat builds through the month, with the worst of it after the solstice and into January and February. Early December is the recommended half. One practical note they repeat: the subway is not air-conditioned and is stuffy in summer, so buses, taxis and walking are the way about. The jacarandas have finished by now. The record: 12.1 hours of sun, a 23.7 kph wind and AQI 32.

Colonia's own forum doesn't have much May-specific weather chatter, but one useful data point came up in a beach thread: swimming season here doesn't really start until around Christmas, which confirms May sits well into the cooler off-season. The destination's own climate record fills in the rest - mild autumn days in the high teens C, cool nights, and only occasional rain. It's actually a pleasant month for what Colonia is really known for: wandering the cobblestone, Portuguese-influenced old town without summer crowds or heat.

Forum posters are candid that November weather in Uruguay isn't a guaranteed warm, sunny stretch - it's generally decent for touring but shouldn't be assumed reliably nice. For the town itself, posters consistently praise the UNESCO-listed historic quarter (founded 1680) for its Portuguese-influenced architecture and winding streets, often compared to old Lisbon, calling it clean, safe, and notably friendly and slow-paced. The fast ferry from Buenos Aires (as short as 15 minutes on some routes) makes it an easy day trip or overnight, and posters recommend an early start and staying at one of the town's posadas to properly soak in the pace rather than rushing through on a single-day visit.
