Climate
Sao Tome and Principe has a tropical climate with relatively consistent temperatures throughout the year. The temperature typically ranges from the mid-70s to mid-80s Fahrenheit (24 to 29 degrees Celsius), with high humidity levels. The islands experience two main seasons: the rainy season and the dry season.
The rainy season runs from October to May, with the heaviest rainfall occurring from January to May. During this time, the islands are lush and green, with plenty of opportunities for hiking and exploring the waterfalls. However, the rainfall can also cause flooding and make some of the roads and trails difficult to navigate.
The dry season runs from June to September, with less rainfall and generally more sunny days. The ocean conditions are generally calmer during this time, making it a good time for diving and snorkeling.
Best Time to Visit
The best time to visit Sao Tome and Principe depends on what you want to do and see. If you're interested in hiking and exploring the waterfalls, then the rainy season may be the best time to visit. However, if you're looking for more consistent weather and calmer ocean conditions for diving and snorkeling, then the dry season is the better choice.
Another factor to consider is the festivals. Sao Tome and Principe has a number of colorful festivals throughout the year, including the São João Festival in June, the Carnival of São Tomé in February or March, and the Principe Island Festival in August. If you're interested in experiencing one of these festivals, then you may want to plan your trip accordingly.
