American Samoa Weather in April

While other South Pacific destinations begin to cool down in April, American Samoa stays consistently warm, thanks to its tropical location near the Equator.

Expect high humidity and persistently warm weather throughout the month, perfect for those chasing the sun.

In April, daily high temperatures average around 29°C (84°F), while nighttime lows settle at about 26°C (79°F).

The heat can feel more intense due to the humidity, but the islands offer plenty of ways to cool off, from swimming in clear lagoons and exploring waterfalls to relaxing in breezy beach resorts or air-conditioned stays.

Sea Temperature in April

The ocean remains beautifully warm in April, with average sea temperatures around 29°C (84°F). This makes it an excellent time for snorkelling, swimming, paddleboarding and diving, just be sure to apply reef-safe sunscreen before heading into the water!

As the season gradually shifts towards the drier months, April brings slightly shorter days in American Samoa, but still plenty of sunshine.

On average, the islands enjoy about 12 hours of daylight and around seven hours of bright sunshine per day, a bit more than earlier in the year. That means you'll still have ample time to enjoy outdoor activities between occasional tropical showers.

UV Levels During April

UV radiation remains extremely high during April, with levels around 11+ on the UV index at midday.

Be sure to apply high-SPF, reef-safe sunscreen LINK#TT024, wear sun-protective clothing, and seek shade during peak hours to protect your skin while exploring the islands.

Sunrise and Sunset During April

April has daylight hours lasting about 12 hours a day in American Samoa.

• Sunrise: 6:32 am at the beginning of April and 6:15 am at the end of April
• Sunset: 6:30 pm at the beginning of April and 6:13 pm at the end of April.

April is still part of American Samoa's wet season, but rainfall begins to ease compared to the peak months of January and February. You can expect a mix of short, heavy downpours followed by sunshine, so it's best to be ready for both wet and dry conditions when exploring.

According to historical weather patterns, April typically brings around 267 mm (10.5 in) of rainfall, with rain occurring on about 18 days throughout the month.

While that might sound like a lot, most showers are brief and often happen overnight or in the early morning.

If avoiding rain is a top priority, the dry season from May to October might be a better fit. However, if you're prepared with a light rain jacket or umbrella, and a list of rainy day activities. Be sure to check 10 Things to Do in American Samoa on a Rainy Day LINK#TTD064.

April marks the final month of the South Pacific cyclone season, which runs from November to April. While the risk of tropical storms is lower compared to earlier months, there is still a slight chance of cyclone activity in American Samoa during April.

Historically, American Samoa has experienced tropical storms during this period, though such events are rare. One of the most notable recent cyclones was Cyclone Amos in April 2016, which passed near the territory as a Category three storm.

Although the cyclone prompted precautionary evacuations and caused localised flooding and power outages, the damage was far less severe than anticipated.

If you want to avoid the risk of cyclones in American Samoa, it’s best to travel in the dry season. For those planning to travel during March, be aware of what to do if there is a cyclone alert by following our guide, Cyclone Safety in American Samoa LINK#TT030.
