The coastline of white, sandy beaches is further exposed during low tide and draws a large number of tourists. The ocean water temperatures are at the lowest of the year, with the average registering at 81°F (27.2°C). September is a good time to climb Mount Alava with a break in the rain that offers an uninterrupted view of the archipelago of the surrounding islands. Winds are rarely troublesome with moderate speeds that are mostly of the gentle breeze type. Sunny days greet the tourists, whether on the beaches or the mountains and forests.
September is a good time to visit American Samoa with comfortable weather that gradually transitions to hot and humid with the end of the dry season.
