Weather in Medellín, Colombia in December
December is one of the better times to visit Medellín. The city — often called the “city of eternal spring” — sits in the Andean mountains at around 1,495 meters (4,905 feet), which keeps temperatures mild year-round. December falls in a dry season transition, meaning fewer rainy afternoons and more sunny days for exploring the city. If you’re planning a trip to Medellín and still figuring out where to stay in Medellin, that decision shapes your experience as much as the weather does.
December is a great month for first-time visitors, couples, and families comfortable with occasional brief showers. It’s high season, though — prices rise and popular spots fill up fast. Budget travelers and those seeking quieter corners may find other times of the year more practical.

What Medellín December Weather Is Like
Medellin weather in December feels lively and bright. December weather in Antioquia’s capital is defined by mostly clear mornings, some cloud buildup in the afternoon, and pleasant weather that makes the city genuinely walkable. The surrounding mountains stay lush and green without the heaviness of the wet season, and the air is noticeably cleaner than during wetter months.
Mornings and evenings are your best windows outside. Temperatures hover around 22–25°C (72–77°F) before noon, making open-air markets and walking tours comfortable. Temperature changes happen fast after sunset — by 8 or 9pm, a light layer is useful at rooftop bars or outdoor restaurants.
Average Temperatures in Medellín in December
Daytime highs reach 28°C (82°F), occasionally nudging toward 31°C (88°F) on the warmest afternoons. Temperatures remain comfortable by midday thanks to the altitude, but direct sun exposure is real — UV index values run high even on partly cloudy days. The low temperature at night drops to around 16–18°C (61–64°F), which is cooler than visitors from tropical climates expect.
The average temperature across the month sits around 22–23°C (72–73°F). Compared to the wetter shoulder months of September to November, December brings warmer temperatures and noticeably less rain. January is drier and slightly dustier; December sits in a more comfortable middle zone.
Weather conditions are generally stable, with the most reliable weather falling in the first two weeks of the month. From mid-December onward, brief afternoon showers become slightly more common.
Rainfall in Medellín in December
December is part of Medellín’s second dry season — less rain than any other time of year aside from January–February. Early in the month, rain is infrequent. By mid-to-late December, short bursts of rain appear in the afternoons or early evenings as the season transitions.
When it does rain, it tends to be a fast, heavy downpour rather than an all-day drizzle — typically clearing within 30–45 minutes. Plans rarely need cancelling, but a compact umbrella is worth carrying. According to climate data from Weather Atlas, December averages around 70–90mm of rainfall — one of the lowest monthly totals of the year.
Humidity in Medellín in December
Humidity sits around 65–70% — moderate by Colombian standards. It doesn’t produce the heavy, sticky feeling you’d get in coastal cities like Cartagena. Most visitors find it manageable without much adjustment.
That said, the combination of sun and humidity between noon and 3pm is the least comfortable window of the day. Those doing extended physical activity — hiking, paragliding near the city’s outskirts, or cycling — will feel the heat index on sunny afternoons. Breathable clothing makes a meaningful difference.
Is Medellín Busy in December? (Tourism Levels)
Yes — this is peak season. Colombian school holidays begin in mid-December, and international visitors arrive for Christmas and New Year’s. The city’s famous Alumbrado draws domestic tourists from across Colombia, and the Christmas lights draw visitors who wouldn’t normally be here.
Accommodation prices increase significantly compared to other times of the year. Booking 4–6 weeks ahead is reasonable for December. Popular restaurants in El Poblado and Laureles fill up on weekends, and Uber wait times stretch during holiday evenings.
Best Events and Cultural Events in Medellín in December
December has some of the best events of the year in Medellín:
- Alumbrado Navideño (Festival of Lights): Runs from late November through early January. Millions of christmas lights transform the city — the riverfront, Parque Norte, and major avenues are all covered. Best experienced after dark. Crowds peak on weekends and around December 24.
- Christmas Eve (Nochebuena): A major local celebration. Most restaurants close or run limited menus — plan meals in advance.
- New Year’s Eve: Concentrated in El Poblado and around Parque Lleras. Loud, festive, and crowded. Street closures are common.
It’s worth noting that the Feria de las Flores — Medellín’s most famous flower festival and parade — takes place in August, not December. The feria de las flores is a separate event often confused with December festivities. If the flower festival is the main draw, plan your travel itinerary around August instead.
Best Places and Things to Do in December
December’s mild temperatures and less rain make it one of the best times to visit for outdoor activity. A well-planned travel itinerary might include:
- Alumbrado viewing along the riverfront: Free, accessible, and genuinely impressive — the best spots along Parques del Río fill up by 7pm on weekends
- Cable car to Parque Arví: The Metrocable gives panoramic views of the surrounding mountains and delivers you to a nature reserve perfect for exploring the city’s edges
- Comuna 13 walking tour: Street art, outdoor escalators, and city views — all accessible without rain concerns in December
- Day trip to Guatapé: About 1.5 hours out, the reservoir and famous rock are beautiful in December’s dry conditions
- Paragliding near San Félix: December’s reliable clear mornings make this one of the best times of the year for tandem flights above the Aburrá Valley
- Explore Laureles or El Centro on foot: Both neighborhoods reward slow walking — one is local and residential, the other has beautiful colonial architecture and the Museo de Antioquia
- Museo de Antioquia (indoor backup): If an afternoon shower interrupts your itinerary, this is a reliable few hours of shelter and context
What to Pack for a Trip to Medellín in December
- Breathable clothing for daytime: T-shirts, linen shirts, light trousers — the days reach 80°F (27°C) and above
- One mid-layer: A light jacket or cardigan; nights drop to 64°F (18°C) and feel cooler than expected
- Rain jacket or compact umbrella: For short afternoon showers, especially mid-to-late December
- Comfortable walking shoes: The city involves a lot of walking on uneven surfaces; waterproof soles help
- Sunscreen (SPF 50+): UV levels are high at altitude — sunburn happens faster than at sea level
- Sunglasses: Useful both for UV protection and glare on bright mornings
Seasonal Travel Tips for December
- Morning is your ideal time: Plan active sightseeing before noon — weather conditions are most stable and temperatures are around 22°C (72°F)
- Nochebuena (Dec 24) closures: Many local businesses shut down; stock up on supplies or confirm your restaurant is open before heading out
- Book Alumbrado viewing in advance: The light displays are free, but peak-night crowds can be overwhelming without a plan
- Metro over rideshare: Medellin’s metro and cable car system is clean, reliable, and far faster than Uber during holiday traffic peaks
- Airport transfers: Demand spikes in December — confirm prices upfront or pre-book to avoid surge pricing
- Seasonal changes in pricing: Hotels, tours, and even some restaurants adjust rates in December; build a slightly larger budget than you’d need in off-peak months
Weather Hazards in Medellín in December
December hazards are limited. Brief afternoon downpours can cause short-term street flooding in lower-lying neighborhoods near the river — this clears quickly and is rarely dangerous. The bigger practical risk is UV exposure: Medellín’s altitude amplifies sun intensity, and visitors regularly underestimate it.
Cold nights can catch people off guard if they’ve packed only for warm weather — a low temperature of 16°C (61°F) at altitude feels noticeably cool, especially after dark. No major storm or flood risk exists in December compared to the wet season months of April–May or September–October. Per Colombia’s IDEAM meteorological service, December is among the lowest-precipitation months in the Aburrá Valley.
