Find out what the weather is like right now in the city of Tumaco to ensure your trip is comfortable. This section presents up-to-date data, detailed charts, and a forecast for the near future.

Tumaco welcomes travellers with a classic tropical climate characterized by constant warmth and high humidity. The weather here is remarkably stable: the average air temperature remains at a comfortable level of around +25…+26°C throughout the year, changing very little from month to month. This is a place where the concept of changing seasons is quite arbitrary, and summer lasts all year round.

An important feature of the local climate is the regularity of rainfall. Rain in Tumaco is a frequent occurrence, and the number of days with precipitation remains high throughout the year, varying from 20 to 29 days per month. There is no distinct dry period here, so travellers should be prepared for frequent cloudiness and short showers at any time.

Thanks to the consistent temperature regime, you can plan a trip for any date without fearing sudden cold snaps or extreme heat. The mild climate and warm nights create a relaxing atmosphere, ideal for exploring the unique nature of the Pacific coast of Colombia, provided you bring an umbrella or raincoat with you.

The climate in Tumaco is distinguished by amazing stability, typical for the equatorial latitudes of Colombia. Eternal summer reigns here throughout the year, and temperature indicators change very slightly. The average air temperature fluctuates within a very narrow range: from 25.5°C in November and December to maximum annual averages of around 26.3°C in May. This makes the city a predictable destination for travel, where there are no sudden drops in temperature or extreme heat.

The usual division into seasons is quite arbitrary here. The summer months (June, July, August) bring pleasant warmth with average readings of around 25.8°C — 26.0°C, which feels like mild and comfortable weather. The winter period is in no way inferior to summer: even in January and February, the air warms up to 25.6°C — 25.9°C. In essence, the concept of a cold winter is absent in Tumaco — it is always warm, humid, and green here.

Diurnal temperature fluctuations are also minimal, creating a sense of a consistent climate around the clock. The difference between day and night readings is only 2-3 degrees. During the day, the thermometer usually rises to 26.6°C — 27.6°C, and at night it drops only to a comfortable 24.4°C — 25.1°C. This insignificant amplitude means that you will hardly need warm clothes for evening walks, as the nights here remain tropically warm.

The climate in Tumaco is characterized by high humidity and frequent rainfall throughout the year, which is typical for this region of Colombia. It is difficult to single out a distinct dry season here, as it rains with enviable regularity almost every month. Precipitation falls exclusively in the form of rain, since the air temperature remains consistently high (about 25–26°C) all year round.

The wettest months in terms of rainfall frequency are January and May. At this time, the number of rainy days reaches a maximum — about 29 days a month, meaning it can rain practically every day. The volume of precipitation in these months is also slightly above average, reaching 14–15 mm. June and July are also distinguished by a high frequency of rains, so an umbrella or raincoat will be necessary for travellers at any time.

A conditional decrease in precipitation is observed towards the end of the year. The "driest" month can be called November, when the number of rainy days decreases to 20, and the volume of precipitation drops to 5 mm. In the period from August to October, less precipitation falls by volume (about 6 mm), but the frequency of rains remains high — from 24 to 27 days a month. Thus, when heading to Tumaco, one should expect frequent, but judging by the volume, often short-lived or drizzling rains.

Tumaco welcomes travellers with a warm tropical climate all year round, so the basis of your wardrobe should be light and breathable items. The air temperature here holds steadily at a comfortable mark of around +25...+26°C, so you will need T-shirts, shorts, loose trousers, and summer dresses. Given the high humidity, it is better to prefer clothes made of quick-drying fabrics, as items made of thick cotton may remain damp for a long time.

Since precipitation falls very often (from 20 to 29 rainy days per month), rain protection is a critically important part of your luggage. Be sure to take a compact raincoat or a light waterproof windbreaker that can be quickly put on during a sudden downpour. Footwear should be comfortable for walking and resistant to moisture: trekking sandals or light sneakers that are not afraid of water and dry quickly are ideal.

Despite the frequent cloudiness, the sun in these latitudes is active, so do not forget to pack sunscreen with a high protection factor, sunglasses, and a hat in your suitcase. Also, insects can be active in the humid climate, so a high-quality repellent will become your indispensable assistant. For evening walks by the ocean, a light long-sleeved sweater may be useful to protect yourself from the sea breeze.
