São Tomé in March
Not the best time
March catches São Tomé in transition - still hot but increasingly wet and sticky. The shoulder season pricing is tempting, but you'll spend more time dodging afternoon downpours than you might like.
Weather
March marks the transition into the wet season as afternoon thunderstorms start rolling in from the Atlantic. Mornings are often sunny and hot, but by 2pm you'll hear rumbling thunder. Humidity begins climbing back up, making the heat feel more oppressive.

All Months
The dry season from June to September offers the most reliable weather, with temperatures hovering around 80°F and minimal rainfall. December and January work well too — still relatively dry but with more afternoon showers. Here's the reality: São Tomé sits on the equator, so it's always humid and temperatures barely fluctuate. The wet season from March to May brings daily downpours that can wash out roads and cancel boat trips to nearby islands. But even during dry months, pack rain gear. Afternoon thunderstorms are part of life here. October and November see the heaviest rains and roughest seas. If you're planning to hike in the interior or visit Ilhéu das Rolas, stick to the drier months when trails are more accessible.
