Medellín in December — Full Picture
December brings back the dry season and one of the most festive times to visit. The weather turns sunnier and drier (around 85mm of rain) at the usual mild 28°C/17°C, and the city lights up with the Alumbrados Navideños — Medellín's spectacular Christmas light displays along the Medellín River, among the most famous in Latin America.
The dry, clear weather is great for the outdoor highlights — Comuna 13, the Guatapé day trip, the Metrocable, paragliding — and the evenings are made for strolling the river lights, which typically run from early December into January.
The trade-off is the holiday peak: from mid-December the city fills with returning Colombians and visitors, and prices climb, so book 2-3 months ahead for the Christmas-New Year stretch. Día de las Velitas (Dec 7) kicks off the season with candles and lanterns.
Note: extreme equatorial UV (index 11) under the bright December sun — SPF 50+ and a hat by day, with a light layer for the cooler evenings spent among the lights.
What to Wear & What to Pack
Return of the dry season plus the holiday Alumbrados lights — warm around 28°C/17°C, sunnier with fewer showers. Light daytime clothing and a layer for evenings. Extreme UV (11) — SPF 50+, hat, sunglasses essential.
