Sao Tome Weather in August

August: dry-season days

August feels warm and fairly steady, with highs near 25°C and little rain. It's one of the best months for exploring São Tomé Island: walks around Monte Café's old coffee estates and trips to São Nicolau waterfall are less likely to be interrupted by heavy showers. The coast is good for beach time, though cloud often softens the sunshine and the air stays humid.

Rain falls on about seven days, much like July. September gets wetter, so August is a good choice if you want to see more of the island by road. Still, don't expect every day to be bright. The forest can be slippery after rain, and rough seas can disrupt boat trips.

Whales and August holidays

Humpback whales pass through waters around São Tomé during this season. If you're keen to see them, ask local operators in the capital about trips and sea conditions. Sightings aren't guaranteed, and a boat outing may not suit you if you're prone to seasickness.

August 15 is the Catholic Feast of the Assumption, observed in São Tomé and Príncipe. It's a public holiday, though celebrations and opening hours can vary. If you're visiting churches or smaller towns, expect some businesses to close.

Crowds and local tips

August is high season alongside July, so popular stays and tours can be busier than in wetter months. It's not a huge resort crowd, but you may have less choice than during the quieter, rainier part of the year. Prices can also be firmer; compare options before settling on a place.

If you hate crowds, head for the beaches on weekdays rather than relying on a quiet weekend. For a practical local tip, ask about road conditions before driving to São Nicolau waterfall: the final stretch can be rough, especially after rain.
