When is the Peak, Shoulder and Off-Season in American Samoa?

American Samoa experiences three general travel seasons: high, low, and shoulder. But unlike busier destinations, this paradise rarely feels crowded, so no matter when you visit, it’s easy to find peace, space and local charm.

High Season (July - August & December - January)

The first high season is July to August, when school holidays in New Zealand and Australia, combined with dry, pleasant weather, make it the most popular time for international visitors.

The second runs from mid-December to mid-January, when many American Samoans living abroad return home for the holidays. Expect to see more locals enjoying the beaches, waterfalls, and cultural events during this festive time.

Low Season (February - April)

Tourism slows down in February and April, partly due to the higher chance of rainfall and the region's cyclone season. However, some travellers from colder climates visit during this period to escape winter, and you’ll enjoy quieter hikes, accommodations, and attractions.

Shoulder Seasons (May - June & September - November)

The shoulder months combine the best of both worlds, fewer crowds and relatively stable weather. September and October are especially great, with clear skies, good visibility for snorkelling and occasional humpback whale sightings.

Weather is often a key factor when deciding the best time to travel to American Samoa. Like many South Pacific islands, American Samoa experiences two main seasons: the dry season (May to October) and the wet season (November to April).

If you’re visiting American Samoa with the intention of doing a particular activity, then be sure to research the best seasons to do it! Scuba diving, surfing, fishing, events, festivals and even waterfalls all have “seasonal” elements.

The Best Time for Surfing in American Samoa

The dry season, running from May to October, is the prime time to catch waves in American Samoa. This period sees steady south swells rolling in, accompanied by strong southeast trade winds that shape the surf along the islands' coastlines.

Despite its excellent conditions, American Samoa remains an uncrowded and underrated gem, making it a must-visit for surfers seeking off-the-radar breaks.

The Best Time for Scuba Diving in American Samoa

The best time for underwater activities in American Samoa is during the dry season from May to October, when visibility is at its clearest and seas are calmer.

Top spots include Alega Beach, a protected bay ideal for beginners and seasoned divers alike; Fagatele Bay, a deep dive site in the National Marine Sanctuary known for turtles and reef sharks; and Taema Bank off southern Tutuila, where vibrant reefs and diverse marine life await.

The Best Time for Fishing in American Samoa

American Samoa offers excellent fishing opportunities year-round, but certain game species are most abundant during specific seasons:

• Yellowfin tuna & blue marlin – best from November to May
• Dogtooth tuna, mahi-mahi & sailfish – more common between September and November

Fishing is permitted throughout the National Park of American Samoa for subsistence purposes only, with no commercial sales allowed. But before you cast your line:

• Always seek village permission first and avoid fishing on Sundays
• Only use traditional gear (rod & reel, net, basket, or pole spear)
• Stay alert for slippery rocks and hazardous conditions
• No permit or license is needed for non-commercial fishing in park waters

The Best Time for Waterfalls in American Samoa

American Samoa boasts several stunning waterfalls, especially during the wet season. Faga'alu Waterfall and Laufuti Falls flow beautifully from November through April, when rainfall is highest. However, heavy rain can make some falls dangerous; swimming at creek-fed drops may become unsafe due to strong currents and slippery rocks.

During the dry season, from May to October, many smaller cascades lessen or even dry up. If you're hoping to see falls in full flow, aim for the shoulder months of April and October, when rainfall still replenishes the streams without the risks of heavy monsoons.

The Best Time for Events and Festivals in American Samoa

American Samoa has a small but meaningful calendar of cultural events, most of which are rooted in tradition and community celebration. While dates may vary each year, here are some highlights to consider when planning your visit:

• Flag Day Celebrations – 17 April
• National Tourism Week – First week of May
• Moso'oi Festival of Arts & Humanities – October
• White Sunday – Second Sunday of October

If you're looking to explore American Samoa without breaking the bank, visiting in the right season can make a noticeable difference, especially when it comes to accommodation and flights.

Best Time for Affordable Accommodation in American Samoa

The most budget-friendly months are during the low season, typically from mid-January to April and September to early December. Hotels and guesthouses often lower their rates or offer promotions like "stay five nights, pay for four" to attract travellers.

While American Samoa isn't packed with tourists even in high season, these months offer the best chance for discounts.

Best Time for Cheaper Flights to American Samoa

For lower airfare, consider travelling during February, March or late August through October. Flights from Honolulu (the main international route) tend to be more affordable outside of peak U.S. and holiday seasons. Find out more on Which Airlines Fly Directly to American Samoa? LINK#T027

What About Car Rentals?

Car rental prices in American Samoa are fairly consistent year-round, but you might find limited vehicle availability during holiday periods, so booking early is still wise if you're travelling in December or July.
