Samoa Weather in October

October in American Samoa brings consistent tropical warmth, with daytime highs averaging 29°C (84°F) and evenings slightly warming up to a pleasant 23°C (73.4°F). Humidity levels stay on the higher side, wrapping you in that classic island air.

While this is technically the tail end of the dry season, the air starts to feel a little more tropical. The sea temperature is still inviting, remaining just slightly cooler than the summer months, perfect for swimming, snorkelling and diving.

Sea Temperature in October

American Samoa enjoys warm ocean waters year-round, and October is no exception. With sea temperatures averaging 28°C (82°F), it's an excellent time for water-based adventures like kayaking, snorkelling and paddleboarding.

American Samoa continues to enjoy long, bright days in October. The islands experience around 12 hours of daylight each day, with roughly five hours of sunshine on average, just slightly lower than in September. Still, there's plenty of sun to go around for beach days, hikes or scenic drives along the coast.

UV Levels During October

October brings intense UV levels back into play, typically reaching 11+ on the UV index around midday. Be sure to pack reef-safe, high-SPF sunscreen and reapply frequently, especially if you're outdoors or in the water, see The Best Sunscreens for American Samoa + Sun Protection Tips.

Sunrise and Sunset During October

In American Samoa, daylight hours hold steady in October.

• Sunrise: Around 6:00 am at the beginning of October, shifting to about 5:43 am by the end of the month
• Sunset: Around 6:14 pm at the start of the month, moving to approximately 6:20 pm by the end

Although October marks the tail end of the dry season in American Samoa, rainfall begins to pick up slightly. Expect around five days of rain throughout the month, though showers are often short and mostly occur during the evening or overnight.

Still, it's a good idea to pack a lightweight rain jacket just in case a tropical downpour catches you by surprise.

American Samoa receives an average of 233 mm (9.2 in) of rainfall in October, which is still relatively moderate compared to the wetter months ahead.

The South Pacific cyclone season starts in November LINK#TT055 and ends in April. As such, October is one of the better months to avoid tropical cyclones in American Samoa with a very low risk of tropical storms developing.

Other months that have a low risk of tropical storms in American Samoa include June, July, August and September. Find out more about tropical storms in our guide, Cyclone Safety in American Samoa LINK#TT030.

October is perfect for exploring American Samoa, with fewer tourists, milder humidity and better deals before the wet season. Whether seeking a relaxed beach escape or adventure-packed trip, American Samoa's rugged beauty and cultural richness shine in October.

Tutuila – The main island and home to capital Pago Pago, Tutuila is most accessible and developed. October brings fewer crowds whilst exploring dramatic coastlines, secluded beaches like Two Dollar Beach and scenic hikes within National Park of American Samoa. Don't miss panoramic views from Mt Alava or snorkelling at Fagatele Bay Marine Sanctuary.

Ofu and Olosega – For true off-grid paradise, head to the Manuʻa Islands, especially Ofu. Known for pristine South Pacific beaches, this remote spot suits travellers seeking solitude, crystal-clear waters and vibrant coral reefs. Plan ahead, as access requires flights and boat rides.

Better yet, visit both! October's calm weather and manageable rainfall make it perfect for experiencing American Samoa's diverse landscapes and laid-back island life. Check out The Complete Travel Guide to the Manu'a Islands LINK#D012

Be prepared for American Samoa in October by packing these few seasonal essentials:

• Light clothing layers for the day (preferably linen, bamboo or merino so it is super light - we like the sustainable bamboo clothing of Moso Morrow)
• Light long-sleeved tops (to cover from sun and mosquitoes)
• Light pants/trousers/skirt (to cover the knees when appropriate – villages or church services or to protect from mosquitoes when hiking, for example)
• Sunhat
• Sunglasses
• Swimwear
• Rash vest (we like the UV-protecting Sharkskin rashies)
• Closed walking shoes
• Flip-flops/jandals/sandals
• Insect repellent
• High-factor sunscreen (that’s reef-safe and water-resistant).
