The quick version: Medellín runs on Colombia Time (UTC-5) and does not use daylight saving, so the clock never changes. That puts it on the same time as New York and Miami in the northern winter, and one hour behind them in summer. The weather barely changes either: it is spring-like all year, averaging about 22°C (72°F), and the only real variable is rain. Pack light layers, good sunscreen, and an umbrella if you are coming in a wet season. Leave the heavy coat at home.
Medellín gets called the “City of Eternal Spring,” and it earns the nickname. The combination of equatorial latitude (just over six degrees north) and high elevation (around 1,500 meters) produces an unusually stable climate: temperatures in the high teens to high twenties Celsius year-round, no real winter, no real summer, and the longest and shortest days of the year differing by less than an hour. Here is what that actually means in practice, plus the time-zone basics for travelers calling home.

Where Medellín Sits
Medellín is in northwestern Colombia, in the Aburrá Valley, a long narrow valley running roughly north to south through the central Andes. The city is about 240 kilometers (around 150 miles) northwest of Bogotá as the crow flies, though the road distance is roughly twice that. Most of the urban area sits between 1,400 and 1,700 meters above sea level. Hillside neighborhoods run up to 1,800 meters, and the rural corregimientos around the city, including Santa Elena, San Antonio de Prado, and San Cristóbal, reach as high as 2,500. The peaks surrounding the valley, including Cerro Padre Amaya and Alto de Boquerón, rise above 2,600 meters and form Medellín’s visual horizon in every direction.
Inside the city, Cerro Nutibara (home to the Pueblito Paisa replica village) and Cerro El Volador (a pre-Hispanic archaeological site) are the two small park hills that punctuate the otherwise flat valley floor. If you head up to Santa Elena or out to the higher towns on a day trip, expect it to feel a few degrees cooler than the city.
The Time Zone
Medellín runs on Colombia Time (COT), which is UTC-5. Colombia does not observe daylight saving time, so the clock here never changes. That single fact is what makes the comparisons below shift through the year: it is everyone else who springs forward and falls back, not Colombia.
For most of the year, roughly November to March, when the US is on standard time, Medellín matches New York and Miami (Eastern) and is one hour ahead of Chicago and Houston (Central). For the rest of the year, roughly March to November, when the US is on daylight saving, Medellín is one hour behind New York and Miami and matches Chicago and Houston.
Here is the quick reference:
| Place | Time difference from Medellín |
|---|---|
| New York / Miami | Same in winter, 1 hour ahead in summer |
| Chicago / Houston | 1 hour behind in winter, same in summer |
| Los Angeles | 2 to 3 hours behind |
| London | 5 to 6 hours ahead |
| Madrid | 6 to 7 hours ahead |
| Lima / Quito | Same, all year |
Within South America, Medellín keeps the same time as Lima and Quito year-round, which makes scheduling across the region simple.
The Climate
Two things shape Medellín’s weather: the equator and the altitude. Sitting just over six degrees north of the equator means daylight hours barely change from one season to the next, and there is no real seasonal temperature swing. Sitting at 1,500 meters means it never gets hot in the way the latitude alone would suggest. Most days reach the mid-20s Celsius (mid-70s Fahrenheit), the yearly average sits around 22°C (72°F), and most nights drop into the high teens (low to mid 60s). It is genuinely spring-like, every day, all year.
What does change is the rain. Medellín has two wet seasons, roughly April to May and September to November, when afternoon thunderstorms are the norm. The rain tends to come in concentrated bursts rather than all-day soaks: a typical wet-season day starts sunny, clouds over by mid-afternoon, drops a sharp half-hour of heavy rain, and clears by evening. The drier windows in between, December to March and a shorter one in June and July, are when most visitors come, and for good reason. For a month-by-month breakdown of rainfall and the smartest time to plan a trip, see the guide on the best time to visit Medellín.
A few practical climate notes:
The UV index is high. The altitude thins the atmosphere just enough that sunburn comes faster than you would expect, even on overcast days. This is not a place to skip sunscreen.
Humidity averages around 65%. Comfortable most of the time, but it does make rainy days feel cooler and stickier than the thermometer suggests.
Air quality is a real issue at certain times of year, particularly March to April and September to October, when temperature inversions in the valley trap pollution and dry-season fires from outside the city add to it. The city has invested heavily in electric buses, bike lanes, and a monitoring network, but if you have respiratory sensitivities, plan around those windows. There is more on this in the safety guide.
What to Pack
What to Pack
For most stays, you need less than you think. Medellín’s steady, mild weather means one set of clothes works for the whole trip, with small adjustments for rain and sun. The essentials:
- Light layers for the day, plus a long-sleeve shirt or a thin sweater for cooler evenings and higher-altitude spots.
- Comfortable walking shoes. The city is hilly and you will be on your feet a lot.
- Strong sunscreen, sunglasses, and a hat. The high-altitude UV is the thing most people underestimate.
- A small folding umbrella or a light rain jacket if you are visiting in a wet season. The rain is not constant, but when it lands it is heavy enough to soak you in a block.
- A refillable water bottle. Medellín’s tap water is safe to drink, so there is no need to buy bottled.
What to leave at home: a heavy coat. Medellín almost never gets cold enough to need one, even at night. If your trip includes a high-altitude hike or a pre-dawn start, a packable jacket covers it, but for the city itself you will never touch a winter coat.
Frequently Asked Questions
What time zone is Medellín in? Colombia Time, UTC-5. The whole country uses the same zone.
Does Colombia observe daylight saving time? No. The clock in Medellín stays the same all year, which is why the gap between Medellín and cities that do use daylight saving shifts by an hour twice a year.
What time is it in Medellín compared to the US? During the northern winter, Medellín matches New York and Miami and is an hour ahead of Chicago. During the northern summer, it is an hour behind New York and matches Chicago.
What is the weather like in Medellín? Mild and spring-like year-round, averaging about 22°C (72°F), with warm days, cool evenings, and no real seasons. The main variation is rainfall, which peaks roughly April to May and September to November.
What should I pack for Medellín? Light layers, comfortable walking shoes, strong sunscreen, and a small umbrella or rain jacket in the wet season. Skip the heavy coat.
