Weather in American Samoa

American Samoa sits in the South Pacific tropics and experiences a warm, humid climate year-round, with temperatures hovering between 24°C and 31°C regardless of season. The dry season, running from May through October, is generally considered the best time to visit. During these months, rainfall is lower, humidity is more manageable, and trade winds keep temperatures comfortable. This is the ideal window for hiking in the national park, snorkelling the coral reefs, and exploring the islands' rugged coastline without the threat of prolonged downpours.

The wet season from November through April brings higher rainfall and occasional tropical cyclones, with February and March being statistically the rainiest months. That said, rain in the tropics is rarely all-day affairs, and many travellers visit year-round without issue. The territory is hit by tropical storms periodically — Cyclone Gita in 2018 caused significant damage — so it's wise to monitor weather forecasts if travelling between December and April. Events like Flag Day (April 17), celebrating American Samoa's designation as a US territory, offer a vibrant cultural celebration worth timing your visit around.
