Traveller notes on Medellín in May

Other months in Medellín

Regulars are specific that rain here varies so much by neighborhood that it can be genuinely pouring in Poblado while a nearby area like Laureles stays sunny at the very same hour, weather apps notoriously unreliable at capturing that hyperlocal split. Our row backs that hot, genuinely wet read, 28.7C reading as a hot 33C, over 18.1C nights, with a substantial 222.6mm of rain across an extraordinary 26.5 days and humidity at 84 percent. Regulars are consistent that a downpour typically lasts only 30 minutes to an hour, usually arriving in late afternoon, with plenty of nice weather still available earlier in the day. A compact umbrella carried at all times is the standard advice rather than trusting any single forecast. The record: 9.9 hours of sun, a 6.6 kph wind and AQI 49.

The city of eternal spring earns the name in our data: every month of the year tops out between 27 and 29C, and June reads 28.2C over 17.8C, which matches the board's mid-eighties by day and mid-sixties at night almost exactly. The rain column looks alarming at 26.7 days, and regulars defuse it before you can worry - it rains nearly every day but not all day. Sunny morning, shower from about four, sixty to ninety minutes, done. Plan the outdoors for the first half of the day and the 215.7mm stops mattering. At 87.3 percent humidity 28C reads as 32C, which is the one real cost. The record: 9.6 hours of sun, an almost still 6 kph wind and AQI 47.

The eternal spring is real in the sense that matters: regulars put the whole year at roughly 77 to 82F by day and 58 to 63F at night, and our February reads 28.9C over 18C. They call February part of the drier season, December to March, and our row looks like a flat contradiction at 166.7mm across 21.5 precipitation days. Their own description resolves it - it rarely rains all day here, sometimes in the morning and sometimes in the afternoon but not usually both - which makes those 21.5 days about eight millimetres each. Flash afternoon thunderstorms are the usual form. The record: humidity 82 percent, 9.9 hours of sun, a 5.4 kph wind and AQI 56.

August in the city of eternal spring is warm, flowery and wetter than the nickname implies - our row counts 24 precipitation days carrying 178.8mm, which is most days of the month. The forum's correction is about timing rather than quantity: when it rains here it is usually late afternoon, evening or the middle of the night, often predictable almost to the hour, so the daylight hours mostly survive. They are also blunt that Colombian weather apps are useless inland, forecasting rain and thunderstorms every single day, because microclimates, mountains and altitude defeat them. August still has plenty of flowers, if fewer than July. The record: 29C days that feel like 33C, 18C nights, humidity 82 percent and 10.3 hours of sun.

    Colombia moves most of its public holidays onto a Monday, so the country takes a long weekend roughly every month. Guatape, Jardin and the road out of the valley are solid on every one of them. Source ↗
