American Samoa sits in the South Pacific tropics and is warm year-round, but there is a clear distinction between seasons.
Dry season (May–October) is the better time to visit. Trade winds keep temperatures around 27–30°C, humidity is manageable, and the seas are calmer — important for snorkeling at Alega, where swell and current can make the channel unsafe. June and July are the driest months and the most reliably good for reef visibility.
Wet season (November–April) brings higher humidity, heavier rain, and the risk of tropical cyclones. Rainfall is heavy at any time of year near Rainmaker Mountain, but between November and April short intense downpours are the norm rather than the exception. Cyclone season peaks December–March; a major cyclone is rare but possible. The reef remains accessible between storms, and the landscape is spectacularly green.
The tattoo festival (Pe'a Festival) takes place in Alega annually, usually in late October or November, drawing traditional Polynesian tattoo artists (tufuga ta tatau) and enthusiasts from across the Pacific. Dates vary; ask at Tisa's or check with the American Samoa Office of Tourism for the current year's schedule.
Sunday: The village observes Sunday strictly. Do not visit on a Sunday unless specifically invited. This is not a tourist advisory — it reflects genuine village law and respect for fa'a Samoa.
