Average temperature across Samoa in March.
March continues the cycle of intense, often dramatic downpours across the Apia area; this is part of the hot, wet season when the air feels thick and vegetation is glossy. Cyclone risk is highest in January-March, so keep an eye on advisories in Apia and expect occasional airport or ferry cancellations. When skies clear, the city and nearby coastal walks are lush and empty of tourists, a good time for low-key cultural visits if you can be flexible.

March usually remains in the thick of the rainy season for the south coast, with frequent heavy showers and occasional cyclone impacts making sea conditions rough and unpredictable. That said, when the weather clears the beaches and ocean pools glisten and waterfalls inland flow strongly, creating dramatic day-hikes. Expect planned activities like boat trips or snorkeling to be cancelled more often; flexible bookings are essential.
March keeps the interior lush and vibrant but often waterlogged: rivers can rise quickly and small streams used as crossings may be treacherous after storm cells. Visibility on ridge trails is often low in cloud and fog, which reduces long-distance views but accentuates the jungle experience. If you plan inland trekking, arrange local guides and be prepared for trail closures; the rewards are dramatic cascades and near-empty paths.

March remains unsettled, with frequent heavy showers and the highest cyclone risk window for Savai’i; waves and swell can batter the exposed western and southern shores. When the sky clears, the island’s crater lakes and coastal blowholes are at their most dramatic, but outdoor plans should be conditional on the forecast. Local guides are excellent at adjusting plans around weather; rely on them for safe inland excursions.
March keeps the islets in the wet season pattern: hot days, high humidity and occasional powerful storms that can close landings and make swimming unsafe. The quiet marine environment between squalls is beautiful, but if a cyclone warning occurs transfers off the islets will be curtailed. Travellers should book return passages with time buffers and bring mosquito repellent and waterproof clothing.
There are no major festivals or events in Samoa during March to be aware of.
