Climate and Weather in American Samoa

Climate

American Samoa enjoys a warm, humid, and rainy climate year-round. The island experiences two main seasons:

• A long, wet summer season from October through May, and
• A slightly cooler, drier season from June through September.

Weather

Located in the South Pacific Ocean between the Equator and the Tropic of Capricorn, American Samoa has a tropical climate.

• Temperatures are consistently warm to hot year-round, ranging from the high 70s to low 90s Fahrenheit.
• Humidity is high throughout the year.
• Rain showers are frequent and can vary greatly in duration, from just a few minutes to an all-day downpour.

Annual rainfall is substantial:

• Drier areas of the island receive an average of 125 inches of rain per year,
• While the highest mountains can receive up to 300 inches annually.

Tropical storms are more common during the rainy season (November to May), bringing additional weather variability to the region.

What to Wear

• Plan to dress lightly.
• Casual summer clothing like sandals, shorts, and short-sleeved shirts are suggested.
• Rain gear is always a good idea, but keep in mind the high humidity—you may get just as wet wearing a raincoat as going without one!
• If you plan to hike in the park, wear sturdy boots. The trails can be muddy and slippery.
• Bring your own snorkel equipment if you plan to explore the underwater world.

For a closer connection to the local culture, you might want to try a lavalava, a traditional skirt-like garment worn by both men and women in various styles and lengths. Lavalavas are available at many local stores and are a comfortable option in the tropical climate.

Cultural and Modesty Guidelines

Please wear modest clothing during your visit. Bikinis and brief-type swimwear are not recommended in public areas, as local customs call for more conservative attire.
