American Samoa Weather in July

American Samoa in July offers the perfect combination of warmth and comfort. While technically part of the islands' "winter," the weather feels anything but cold. Expect sunny, balmy days where the heat is moderated by lighter humidity compared to the earlier wet season.

Daytime temperatures typically peak around the high 29°C (84.2°F), creating ideal conditions for exploring national parks, lounging at the beach, or taking a dip in the ocean. Evenings remain pleasantly mild with a temperature of 23°C (73.4°F), making it easy to enjoy outdoor dinners or breezy walks without needing extra layers.

Sea Temperature in July

The ocean surrounding American Samoa stays beautifully warm throughout the year, and July is no exception. Sea temperatures remain inviting for swimming, snorkelling and diving, holding steady around 28°C (82.4°F).

July in American Samoa delivers plenty of daylight, with around 11 hours of sun each day, quite generous for the winter season. On average, visitors can expect about five hours of sunshine daily, making it one of the brightest and driest months of the year. Perfect for long beach days, scenic hikes or exploring national parks without having to rush back before sundown.

UV Levels During July

While the sun may feel milder than during the peak of summer, UV levels are still considered very high in July. Around midday, the UV index typically hovers around eight, so sun protection is essential. Be sure to pack reef-safe sunscreen, a wide-brimmed hat and breathable clothing to stay protected while out enjoying the islands.

July is one of the driest months of the year in American Samoa, making it a fantastic time to enjoy the outdoors without much interruption from the rain. While brief showers can occur, they're usually short-lived and often fall during the night, meaning your beach days and hikes are likely to stay nice and dry.

Rainfall totals are relatively low compared to the rest of the year, with July averaging just over 124 mm (4.9 in) of rain, with only five days of rainfall for the whole month. Humidity is present but more manageable, thanks to consistent breezes and cooler evenings.

Whether you're planning a scenic hike through the National Park of American Samoa or looking to relax on the beaches of Ofu or Aunu'u, July's dry conditions provide one of the most reliable weather windows of the year.

• Closed walking shoes
• Flip-flops/jandals/sandals
