What is the Weather Like in American Samoa in July?

July is one of the most popular months to visit American Samoa and it's easy to see why. This time of year marks the height of the dry season, bringing plenty of sunshine, warm breezes and a little less rainfall. It's the perfect setting for national park hikes and exploring the island's historical and cultural sites with little interruption from the weather.

While the temperatures are warm and tropical, they're also more comfortable compared to the humid highs of earlier months. Days tend to be cooler and pleasant, especially with the tradewinds blowing, making it easy to enjoy most activities apart from snorkelling, diving and boat trips when the winds pick up.

Since July is part of the peak travel season, and with very little tourist accommodation available, it's advisable to plan and book your visit early. And if you're wondering what to expect in terms of sunshine hours, rainfall or sea conditions, keep reading this guide to learn more about the weather in American Samoa in July.

5 Tips for Visiting American Samoa in July

  1. While July is considered the dry season, expect rain at any time!
  2. The best snorkelling, diving and boat trips are in the morning before the winds pick up in the afternoon.
  3. Apply high-factor reef-safe sunscreen in regular intervals.
  4. July is not only the peak tourist season but also the local school holidays, so you’ll need to plan your trip early to secure your top choice of accommodation and flights where possible.
  5. 16 July is Manu'a's Flag Day, which is an eventful time to visit Ta'ū, Ofu and Olosega!

Typical Temperatures 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. What's more, July's tradewinds also help manage the heat.

Daytime temperatures typically peak around the high 84.2°F (29°C), 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 73.4°F (23°C), 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 82.4°F (28°C).

Hours of Sun in July

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.

Rainfall in July

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, especially in Pago Pago, 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 4.9 in (124 mm) 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, July's dry conditions provide one of the most reliable weather windows of the year.

The Best Places to Visit in American Samoa in July

We highly recommend exploring both Tutuila and the Manu'a Islands in July, and here's why.

Tutuila, the main island, is a great starting point. Wander through the colourful town of Pago Pago, hike through the National Park of American Samoa for sweeping coastal views, and discover hidden gems like Fagatele Bay and Blunt's Point. The weather this month makes outdoor exploration a dream—think sunny hikes and breezy afternoons by the water.

However, the real highlight of visiting American Samoa in July is experiencing Ta'ū Island in the Manu'a group during Flag Day celebrations on July 16. The festivities typically span three days and offer an incredible glimpse into Samoan culture with traditional ava and flag-raising ceremonies, and vibrant celebrations throughout the island. It's a unique opportunity to witness authentic cultural traditions in one of the most remote and beautiful settings in the Pacific. See more on 20 Best Things to Do in the Manu'a Islands.
