Weather in San Andres

Are you planning a trip or simply interested in the weather in the city of San Andres? In this section, you will find up-to-date weather reports, detailed forecasts, and clear charts that will help you stay informed about all weather changes.

The city of San Andres in Colombia is distinguished by a typical tropical climate, characterised by warm weather throughout the year. Average annual temperatures fluctuate insignificantly, remaining in a comfortable range from 26°C to 28°C. This means travellers can expect consistently warm days and nights, regardless of the time of their visit.

Despite the temperature stability, two main seasons can be distinguished in San Andres based on rainfall. The drier period usually falls during the months from February to April, when precipitation is minimal, and the number of rainy days decreases noticeably, especially in April. From May to November-December comes the season with more frequent rains. During this time, both the total amount of precipitation and the number of days with rainfall increase, reaching a peak in October and November, when it rains almost daily, although it is not always torrential.

Thus, when planning a trip to San Andres, it is worth considering that warm tropical weather awaits you. If you prefer more sunny days and less chance of rain, it is better to choose the period from February to April. In other months, especially from May to November, one should be prepared for more frequent, but usually short-lived tropical downpours, which refresh the air and sustain the island's lush greenery.

The climate in San Andres is characterised by remarkable temperature stability throughout the year. Average annual temperatures fluctuate within a very narrow range, creating almost invariably warm weather. The hottest month is usually September, when the average temperature reaches 27.6°C, and maximum daytime figures can rise to 28.5°C. It is slightly cooler in March, with an average temperature of 26.1°C, while minimum night-time temperatures rarely drop below 25.6°C. Overall, the annual range of average temperatures is from 26.1°C to 27.6°C, making San Andres an ideal place for lovers of consistently warm weather.

The period that can loosely be called "summer" and the hottest time covers the months from April to November. During this time, average daytime temperatures hold steady at 27-28°C, and sometimes higher. For example, in June, August, and September, average maximum temperatures reach 28.1°C, 28.2°C, and 28.5°C respectively. The "winter" months, from December to March, bring only a slight decrease in temperature. Average maximum daytime temperatures during this period vary roughly from 26.6°C (in March) to 27.4°C (in December), and average minimum night-time temperatures stay in the range of 25.6°C – 26.1°C. This means that even in the "coolest" months, San Andres maintains very warm and comfortable weather, resembling summer in temperate latitudes.

One of the key features of the temperature regime in San Andres is the minimal fluctuations in temperature not only throughout the year but also throughout the day. The difference between average maximum daytime and average minimum night-time temperatures is usually only 1-2 degrees Celsius. This creates a sensation of constant, even warmth without sharp changes, making a stay on the island comfortable at any time of day or night. Such temperature stability is a characteristic feature of the island's tropical climate.

San Andres experiences a tropical climate, characterised by alternating wet and dry periods during the year, rather than the classic four seasons. Precipitation here falls exclusively as rain, as high temperatures persist year-round, precluding snowfall.

The driest period in San Andres occurs in late winter and early spring, specifically from February to April. During these months, precipitation is minimal – averaging just 1 mm in February, March, and April. April can be considered the driest month, as it registers the fewest number of days with precipitation – about 8. In February and March, there are also few rainy days, approximately 13-14, but the total amount of moisture remains extremely low.

The rainy season usually begins in May and reaches its peak in autumn, continuing until the beginning of winter. The wettest month is October, when an average of 10 mm of precipitation falls, and the number of rainy days reaches 28. June, July, and August are also characterised by high humidity: precipitation amounts to 6-7 mm, and it rains almost daily, tallying 26-27 days with precipitation. Interestingly, even in the wettest periods, the total amount of precipitation is not extremely high, which may indicate frequent but perhaps short-lived or light rains. November and December also remain quite wet, with 28 and 26 rainy days respectively, although the volume of precipitation decreases somewhat compared to October.

When planning a trip to San Andres, it is important to consider its tropical climate, which is characterised by warm weather all year round. The average temperature fluctuates between 26-28°C, so the basis of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. Be sure to take T-shirts, shorts, sundresses, and swimwear. Do not forget reliable sun protection: sunscreen with high SPF, sunglasses, and headwear (a hat or cap) will become your faithful companions.

Although the temperature in San Andres is consistently high, the amount of precipitation changes throughout the year. The period from February to April is usually the driest, with minimal rainfall (about 1 mm), although short-term rains are still possible, as even in these months there are between 8 and 14 "wet" days. The wetter season lasts roughly from May to December, with peak rainfall in October (about 10 mm) and the highest number of rainy days (22-28 days per month). Therefore, especially if your trip falls in the second half of the year, it is worth taking a light waterproof jacket or a rain poncho. Clothing made from quick-drying materials will also be very handy.

Besides basic clothing, take care to bring comfortable footwear. You will need sandals or flip-flops for the beach and relaxation, as well as closed, comfortable shoes for walks and excursions. Insect repellent will not go amiss, especially for evening strolls. Although warm clothing is unlikely to be needed, a light cardigan or stole may be useful on cool evenings or in air-conditioned rooms. The principle of layering here essentially comes down to the ability to throw something light over your main outfit.
