São Tomé and Príncipe, located on the equator in the Gulf of Guinea, experiences a tropical equatorial climate with consistently warm temperatures and high humidity year-round. The country has two distinct seasons: a dry season (gravana) from June to September and a rainy season from October to May, with the heaviest rainfall typically occurring between October and December, and again from March to May. Temperatures remain remarkably stable throughout the year, typically ranging from 22°C to 30°C (72°F to 86°F), with minimal variation between months due to the equatorial location. The constant 70% humidity creates a lush, verdant landscape that supports the islands' rich biodiversity and cocoa plantations. While the rainy season brings frequent afternoon showers and occasional heavy downpours, mornings are often sunny, and rain rarely disrupts travel plans entirely. The dry season offers the most comfortable conditions with less rainfall and slightly lower humidity, making it the peak tourist period. However, even during the wettest months, São Tomé maintains its tropical charm with warm ocean temperatures perfect for swimming and diving year-round.

Best Time to Visit

Beach & Relaxation
June to September during the dry season offers the best beach weather with less rainfall, calmer seas, and plenty of sunshine for swimming and water sports.
Cultural Exploration
May to October provides comfortable conditions for exploring colonial architecture, cocoa plantations, and local festivals, with the dry season (June-September) being ideal for outdoor cultural activities.
Adventure & Hiking
June to September during the dry season is optimal for hiking Saotomeandprincipe and exploring rainforest trails, as paths are less muddy and visibility is better for mountain views.
Budget Travel
October to May (rainy season) offers lower accommodation rates and fewer tourists, though you'll need to accept afternoon showers and potentially more overcast days.
