What is the Weather Like in American Samoa in June?
June is when the dry season settles in across American Samoa, making it one of the best times of year to visit. While much of the Southern Hemisphere is in the middle of winter, American Samoa stays wonderfully warm.
This month brings drier skies, lower humidity and plenty of sunshine, perfect for beach days, hiking through the National Park of American Samoa, or exploring quiet coastal villages. June also marks the start of the popular travel season, so expect a livelier vibe around main hubs like Pago Pago and some of the more well-known natural attractions.
However, it's worth noting that whilst many find the weather ideal, the tradewinds can affect the southern coasts of the islands where most snorkelling beaches are located, making for choppy conditions. It's also the start of the peak season in terms of tourism, though this doesn't matter too much as not many tourists make it this far!
For those planning a trip, June offers a balance of great weather and a tiny bit more energy from incoming travellers.

Typical Temperatures in June
June marks the beginning of the dry season in American Samoa, but don't expect a drastic drop in temperatures; this tropical paradise stays warm and inviting year-round. With tradewinds picking up, the constant coastal breeze tends to stop you from overheating.
Daytime temperatures in June typically reach 84°F (29°C), while nighttime lows settle around 73°F (23°C). The humidity begins to ease slightly compared to the earlier wet months, but it still gives the islands that signature tropical feel.
Whether you're relaxing on the beach or hiking through lush rainforests, expect to feel comfortably warm from sunrise to sunset.

June brings some of the shortest days of the year to American Samoa, but don't let that fool you, there's still around 11 hours of daylight to enjoy. It has an average of four hours of sunshine per day. For sunseekers looking to escape the chill of winter elsewhere, June is a brilliant time to visit.

Rainfall in June
June is considered one of the driest and most pleasant months to visit American Samoa. With the wet season firmly behind, rainfall drops significantly, offering more consistent weather for outdoor adventures... Well, apart from the Pago Pago area, where Mt Pioa draws in rainclouds no matter the time of year. No wonder they call it "Rainmaker Mountain".
American Samoa typically receives an average of 6.3 in (159 mm) of rainfall during June, spread across just five rainy days. These rain showers tend to be brief and are often confined to the early morning or evening hours, leaving most of the day sunny and dry.
This makes June an excellent time to explore the islands and hike lush trails without much disruption from the weather.
Tropical Storms in June
June falls outside the official South Pacific cyclone/hurricane season, which runs from November to April. This makes it one of the safest and most stable months to visit American Samoa in terms of weather, with a very low risk of tropical storms or hurricanes.
While hurricanes are rare, it's always a good idea to stay informed during your travels.
If you're particularly concerned about storms, the months of June through September are amongst the most reliable times to visit in terms of cyclone safety. Find out more about tropical storms in our guide, Hurricane Safety in American Samoa.
The Best Places to Visit in American Samoa in June
Just about any island in American Samoa is perfect to explore in June, but if we had to pick, this is what we would go for:
Tutuila – The main and most accessible island offers a rich mix of natural beauty and cultural sites. June is a great time to explore its highlights with typically perfect weather. Hike up Mt ʻAlava in the National Park of American Samoa for panoramic coastal views, swim at stunning beaches like Two Dollar Beach, and visit cultural spots like the Jean P. Haydon Museum.
Aunu'u Island – For a quieter escape, take a short boat ride to Aunu'u Island off the southeast coast of Tutuila. This lesser-visited gem is home to decent snorkelling, typically sheltered from tradewinds, volcanic craters and traditional villages. It's perfect for day trips during this dry, calm weather period.
If you have the time, exploring both Tutuila and Aunu'u gives you a more complete view of American Samoa's natural and cultural landscape. Wherever you go, June offers ideal conditions for outdoor activities and relaxed island vibes.
