About Sao Tome weather

Sao Tome is in Sao Tome and Principe at 0.19°, 6.61°. Right now it’s 28° and mostly cloudy; today’s high is 29° with a 50% chance of rain.

Sao Tome and Principe is a small island nation in the Gulf of Guinea, straddling the equator approximately 250 kilometers off the coast of Central Africa. The two volcanic islands have a tropical wet climate with a pronounced dry season called the Gravana from June to September, when cooler, drier air from the south brings relief from the otherwise persistent heat and humidity. Annual rainfall varies dramatically with altitude and aspect, from about 1,000mm in the drier northeast lowlands to an extraordinary 7,000mm on the southwestern mountain slopes.
