October weather forecast and climate
American Samoa, USA

October is the beginning of the wet season in American Samoa that sees a rise in dampness, humidity, and temperatures. The precipitation is above 10" (254mm) in Pago Pago and averages between 9" (229mm) to 10" (254mm) in the rest of the islands.
The average temperatures are between 77°F (25°C) to 86°F (30°C), and humidity remains above 80%. Afternoon thunderstorms with lightning are frequent in October, along with intense spells of rain. Tidal patterns see a change in the ocean waters and create occasional big waves. Surfers love the waters and are ready for adventure, while sailing boats float dreamily in the clear waters. The sunshine lasts at least 8 hours daily, even though the cloud cover is significant.
An umbrella or a rain jacket is mandatory for outdoor visits, especially in the rainforests, where the canopy of trees can keep conditions wet. October is a reasonable time to visit American Samoa for people who can withstand wet weather.
