What is the Weather Like in Samoa in March?

March is a month in Samoa‘s summer season, also known as the “wet season”. In fact, March is one of the hottest months of the year and sometimes even the wettest. While cyclones are still a risk (albeit a small risk), the risk is not as prominent as in the two previous months. Nevertheless, those still seeking sun between the showers are still likely to find it along with the rewarding experience of travelling during the tourist low season. Check out the typical weather, including temperature, rainfall and more, in this guide to the Samoa weather in March.

5 Tips for Visiting Samoa in March

  1. March falls in the tourist low season, so look out for great deals on flights and accommodation
  2. Wear high-factor sunscreen to protect yourself from the high UV levels experienced in Samoa during March
  3. Because it’s the wet season, there are a few more mosquitoes. Make sure you pack insect repellent and follow our tips in 10 Ways to Avoid Mosquito Bites in Samoa
  4. Want to avoid the rain as much as possible during the wet season? Consider heading to the southeast coast of Upolu (Lalomanu) where the climate is marginally drier
  5. It is true that Samoa can get really hot and humid in March. Don’t worry, there are plenty of opportunities to cool off in the water during the day, while most accommodations are either equipped with air conditioning, ceiling fans or the sea breeze in your open beach fale for pleasant nights.

Tropical Storms in March

The South Pacific cyclone season starts in November and ends in April, making March a month with a higher risk of tropical storms. On average, less than 1 day in March in Samoa is affected by tropical storms.

Historically, Samoa was affected by a tropical cyclone in March 1846, 1869, 1877, 1879, 1883, 1889, 1923, 1926, 1956 and 1961.

One of the most famous cyclone events in Samoa’s history is the 1889 Apia Cyclone. The cyclone swept across Apia during the “Samoan crises” where three colonial powers, the USA, Britain and Germany, lost most of their warships and the Apia Harbour was devasted. Learn more about the social history of this period in A Brief History of Samoa.

There has been no cyclone in recent history that has severely impacted Samoa during March.

If you want to avoid the risk of cyclones in 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 Samoa.
