Medellín sits in the Aburrá Valley at 1,495 metres above sea level - warm enough to feel genuinely tropical but high enough to keep temperatures comfortable rather than sweltering. The city earns its “City of Eternal Spring” reputation honestly: daytime temperatures stay around 22 to 28°C year-round, nights dip to 17 to 20°C, and the landscape stays green in every month. What changes between seasons is mainly the frequency of afternoon rain.
The Two Dry Seasons
December to February: Medellín’s main dry season and its most festive period. From late November through January, the Alumbrado navideño - a city-wide Christmas light installation along the Río Medellín - runs nightly, drawing visitors from across Colombia. December and early January are the busiest and most expensive weeks. February is the sweet spot: dry-season weather with significantly lower prices.
June to August: A mid-year dry window that runs drier than December–February in some years, wetter in others. July is reliably good. August holds the Feria de las Flores, Medellín’s most celebrated annual event and the best single reason to time a visit to the city.
The Wet Seasons
March to May: Rain increases through March and peaks in April and May. Mornings are usually clear; afternoons bring heavy showers. The city’s metro cable cars and graffiti tours run normally - Medellín’s culture doesn’t shut down for rain. Prices are lower than peak months.
September to November: The second rainy season, broadly similar to April–May. October and November are the wettest months. The city is quieter and accommodation is at its cheapest. November’s rain eases as the Christmas season approaches.

Month-by-Month Breakdown
January
One of the best months. The Alumbrado wraps up by January 7 (some installations stay through early January), and after Epiphany the holiday crowds thin significantly. The dry season holds, mornings are clear, and the city operates at a comfortable pace. Day trips to the coffee region - Guatapé, Jardín - work well in January’s reliable weather.
Weather: 22–28°C days, 17–20°C nights. Dry and clear mornings. Crowds: High in the first week; moderate from January 8 onwards. Best for: Day trips, Guatapé, Pueblito Paisa, comfortable city exploration.
February
Arguably the best-value month in Medellín. Dry-season conditions continue with few crowds and prices noticeably below December–January. Mornings are clear and warm, making this an excellent month for Parque Arví, the cable cars, and long days in El Poblado or Laureles.
Weather: 22–27°C. Dry, occasional light showers late in the month. Crowds: Low. Best for: Budget travel, digital nomads, first-time visitors who want reliable weather without peak prices.
March
The transition into the first wet season. Early March is often still dry; by late March, afternoon rain becomes regular. Semana Santa (Holy Week, March or April) drives a sharp increase in domestic tourism - book ahead if your dates overlap. Processional events in the historic areas are worth attending.
Weather: 22–27°C. Rain increasing from mid-month. Crowds: Normal to high during Semana Santa. Best for: Early-month visits, Semana Santa cultural events.
April
Mid-rainy season. Afternoons see regular heavy showers. Mornings remain clear and warm - the cable car routes to Comunas 1 and 2 operate normally and mornings are the best time for them. April’s photography conditions can be spectacular: dramatic cloud formations, lush green hillsides after the first rains.
Weather: 21–27°C. Daily afternoon rain. One of the wetter months. Crowds: Moderate. Mostly domestic visitors. Best for: Photography, cultural visits, budget travel.
May
Similar weather to April - the first wet season peaks. The city’s flower-growing operations in the Santa Elena hills above Medellín are at their most active, supplying markets across the country for Mother’s Day (second Sunday in May), which is Colombia’s biggest commercial shopping day. The metro and shopping centres are packed that Sunday.
Weather: 21–26°C. Frequent afternoon rain. Crowds: Very high on Mother’s Day Sunday; moderate otherwise. Best for: Visiting flower farms, El Centro markets.
June to July
The mid-year dry season begins. June can still have some rain from the tail end of the wet season, but July is reliably drier. Temperatures are comfortable and mornings are clear. July is popular with international travellers - book accommodation 2 to 3 weeks ahead for mid-range options in El Poblado.
Weather: 22–28°C. July consistently dry. Crowds: Moderate to high in July. Best for: Outdoor activities, cycling routes, Guatapé, Parque Arví hikes.
August
The most eventful month in Medellín. The Feria de las Flores runs for 10 days, typically in the first or second week. The centrepiece Silleteros Parade brings 400 to 500 farmers down from the Santa Elena corregimiento carrying elaborate flower arrangements - some weighing 60 to 80kg - through the city centre. Additional events include horse parades, vintage car shows, orchid exhibitions, and live music across every barrio. The metro covers carriages in fresh flowers. Accommodation books out; prices reach a second annual peak after December.
Weather: 22–28°C. Some rain but generally good. Crowds: Very high during Feria week. Book 6 to 8 weeks ahead minimum. Best for: Feria de las Flores - one of Colombia’s most visually distinctive events.
September
The second wet season begins to establish itself. Rock al Parque in Bogotá (September) draws some visitors away, but Medellín itself is fairly quiet. A good month for those who want the city without crowds or tourist pricing. The graffiti tours and Comunas cable routes are best done on clear mornings.
Weather: 21–26°C. Rain increasing through the month. Crowds: Low. Best for: Budget travel, authentic city experience, longer stays.
October
One of the wettest months. Afternoons are reliably rainy and heavy at times. The city’s indoor culture - food halls, the MAMM contemporary art museum, the Botanical Garden’s indoor collections - becomes more central to a visit. Parque Explora is worth a full day in wet weather.
Weather: 20–25°C. Heavy afternoon and evening rain. Crowds: Low. Best for: Museums, food scene, digital nomads settled in for a longer stay.
November
Rain eases through November. From mid-month, dry days increase noticeably and the city starts preparing for Christmas. The first Alumbrado installations typically go live in late November - the riverbank lights are switched on in a public ceremony that draws large crowds. Accommodation prices begin rising from late November as domestic visitors book December trips.
Weather: 21–27°C. Rain tapering. Clear spells from mid-month. Crowds: Low to moderate; building from late November. Best for: Catching the start of Alumbrado before peak prices hit.
December
Medellín’s most celebrated season. The Alumbrado runs nightly - hundreds of thousands of LED lights across Avenida El Poblado, along the Río Medellín, and in Parque de las Luces. The city organises public viewings, and the metro runs extended hours. The event is free. Late December brings the year’s busiest period: flights and accommodation fill up, prices peak, and Medellín’s barrios are loud and festive. Book at least 4 to 6 weeks ahead for stays between December 18 and January 6.
Weather: 22–28°C. Dry season returning fully. Crowds: Very high from December 18 onwards. Best for: Alumbrado navideño, Christmas atmosphere, New Year celebrations in El Poblado.
What to Book in Advance
Feria de las Flores (August): Book 6 to 8 weeks ahead. El Poblado hotels and boutique options near Parque Lleras are first to fill. Mid-range options in Laureles offer better availability.
December 18 to January 7 (Alumbrado season): Book 4 to 6 weeks ahead. Budget hostels are available later, but mid-range and above fills completely.
Semana Santa (March or April): Book 3 to 4 weeks ahead.
June to July: 2 weeks ahead is usually fine for most options.
