Weather in Sao Tome

Be prepared for any of nature's whims in the city of Sao Tome. In this section, you will find the most up-to-date weather information and detailed forecasts for the near future to help you plan the perfect day.

The climate in the city of Sao Tome is typically tropical, hot, and humid. Thanks to its location near the equator, there are practically no sharp temperature changes here, and the weather remains comfortably warm throughout the year. The main difference between seasons lies not in thermometer readings, but in the number of cloudy and rainy days.

Two main periods can be distinguished during the year. From June to September, there is a relatively dry season known as "Gravana," when the number of rainy days is minimal, and the average air temperature drops slightly to a pleasant +24°C. The rest of the time, especially from October to May, humidity rises, and rainfall occurs much more frequently, peaking in December when it can rain almost daily.

For tourists, this means that even in the "coldest" month, July, the weather remains summery and warm. The temperature regime is exceptionally stable, fluctuating within a narrow range from +24°C to +27°C. When planning a trip to the capital of Sao Tome and Principe, it is best to focus primarily on the probability of precipitation, as warmth is guaranteed here in any month.

The temperature regime in the city of Sao Tome is distinguished by enviable stability, characteristic of an equatorial climate. There is practically no extreme heat or sudden cooling here, making the destination attractive all year round. The warmest months are traditionally considered to be February, March, and April, when average indicators confidently stay at the mark of +26...+27°C, and during the day, the air warms up to +28°C. This time offers tourists classic tropical warmth.

The conditional "winter," which in this hemisphere falls on the period from June to August, brings only a light and pleasant freshness. In these months, especially in July and August, the average temperature decreases to +24°C. This period is often called the "Gravana" season, when there is no intense heat, and the weather becomes milder. This is an excellent time for excursions and active leisure, as the sun is not as intense as at the beginning of the year.

A characteristic feature of the local climate is minimal daily fluctuations. The difference between day and night temperatures in the capital of Sao Tome and Principe is practically unnoticeable, amounting to just 1–2 degrees. Even at night, the thermometer rarely drops below +23...+24°C, so evenings here are always warm and comfortable, without the need for heavy clothing.

In the city of Sao Tome, the character of the weather is largely determined by the alternation of dry and wet seasons. The most comfortable and dry period falls in the middle of the year — from June to August. Statistically, the sunniest month is July: at this time, precipitation is minimal, and it rains on average only about 3 days per month, making this time ideal for tourism.

From October to May, a season of high humidity is observed, when precipitation becomes a frequent occurrence. The peak of the rainy season falls at the end of the year: in November and December, the highest number of inclement days is recorded — up to 27–28 days per month. During this period, tourists should be prepared for rain almost daily, although the frequency of rainfall is compensated by the lush blooming of local tropical vegetation.

When planning a trip to Sao Tome, prepare for a hot and humid equatorial climate. The air temperature here is stable throughout the year and stays in a comfortable range of +24...+27°C, so the basis of your wardrobe should consist of light items made from natural breathable fabrics, such as cotton or linen. Loose t-shirts, shorts, and summer dresses will provide necessary ventilation, while a wide-brimmed hat will reliably protect against the active sun.

Luggage contents should be adjusted slightly depending on the season. If the trip is planned for the period from October to May, when the probability of precipitation is high, be sure to pack a light raincoat, a compact umbrella, and quick-drying shoes. In the drier "Gravana" season (from June to September), rains are rare, but evenings can be fresh due to the ocean breeze, so a thin windbreaker or a long-sleeved top will not be amiss.

For long walks around the city and its surroundings, choose comfortable, broken-in shoes, for example, sandals with secure straps or light sneakers. Besides clothing, critically important items for the trip will be high-quality sunscreen with a high SPF factor and insect repellents. We also recommend taking a waterproof case for documents and electronics so that sudden tropical downpours do not catch you by surprise.
