What is the Weather Like in Samoa in January?

Planning on exploring Samoa in January? You would be one of the few who choose to visit the islands during this time, which is ideal for savvy travellers looking to get the best travel deals and experience the islands all to themselves! While temperatures are as hot as they are any time of the year in Samoa, humidity is at its highest, making it all the more refreshing when discovering Samoa’s hidden swimming holes and taking part in the array of water activities. What deters many travellers, however, is the label of the “wet season”, with the likelihood of rain showers and a slight risk of cyclones. But knowing that rain can occur at any time of the year in Samoa, you might just think that January is just as good as any month to visit the islands… Find out more about the Samoa weather in January below!

Tropical Storms in January

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

Historically, Samoa was affected by a tropical cyclone in January 1863, 1865, 1869, 1870, 1877, 1885, 1886, 1890, 1915, 1926, 1933, 1936, 1939, 1944, 1947, 1951 and 1966. In more recent history, Cyclone Heta (January 2004) caused isolated flooding, washed out several roads and damaged powerlines. Cyclone Tino (January 2020) disrupted air and marine travel and caused power outages.

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 January, be aware of what to do if there is a cyclone alert by following our guide, Cyclone Safety in Samoa.

The Best Places to Visit in Samoa in January

Apart from the first week of January, when locals are flying back and forth from Samoa to celebrate the New Year with family, January is a quiet time for tourists to experience the islands. With that in mind, you’re bound to have a great time no matter where you travel to. But if we have to choose the best place to visit in Samoa in January, it would be Upolu.

Upolu – Usually the most popular island to visit in Samoa, Upolu is much quieter during the low season month of January, ideal if you like to experience attractions all to yourself (although, expect tourists to be replaced by eager locals at their favourite swimming holes). If you’re on Upolu at the beginning of the month, don’t miss the New Year’s celebrations in Apia, the first capital to see the New Year. What’s more, Upolu’s array of waterfalls is best seen during the wet season. See what to do in Upolu in the 20 Best Things to Do on Upolu.

That’s not to say that Samoa’s other island, Savai’i shouldn’t be on your bucket list. If you have more time, we highly recommend taking at least a couple of extra days to explore its awesome natural and historical wonders. Find out more about the Samoan islands The Best Islands to Visit in Samoa.
