Eternal spring, explained — what the weather's really like month to month, and the rainy stretches worth planning around.
Medellín sits at ~1,500m, so it's mild all year (low 70s°F) — the city of eternal spring. There's no cold season to avoid; the only variable is rain, with December–March the driest.
Medellín sits in a valley at around 1,500 metres, which gives it a mild, spring-like climate all year — daytime highs in the low 70s°F (21–24°C), cool evenings, and no real winter or summer. That’s the ciudad de la eterna primavera, and it’s why there’s no bad season to come. You pack the same bag in March or October.
The only real variable is rain. December to March is the driest, sunniest stretch and the peak window. April–May and September–November are the wettest, with afternoon downpours that usually clear by evening. Rain rarely ruins a trip here; it arrives on a schedule and leaves just as fast.
Two dates are worth planning around: the Feria de las Flores (early August), the city’s biggest festival, with the famous silletero flower parade; and the Alumbrados, the spectacular Christmas lights along the river through December. Both fill hotels early, so book ahead if you’re aiming for them.
Layers, not extremes. A t-shirt for the day, a light jacket or long sleeves for the cool evenings, comfortable shoes for the hills, and a compact umbrella in the wet months. You won’t need a heavy coat, and you will use the sunscreen.
