5 Tips for Visiting Samoa in December

  1. Book your flights early for this busy time of the year
  2. Pack insect repellent, as mosquitos are more active during the wet season – see the 10 Ways to Avoid Mosquito Bites in Samoa for tips
  3. Don’t expect much activity to happen around the islands during Christmas, Boxing Day and New Year’s Eve – it’s best to retreat to your resort, visit natural attractions, or join the celebrations until services open again
  4. The UV levels are high in December, so be sure to apply high-factor sunscreen regularly
  5. Don’t be put off by the heat – most accommodations are equipped with either air-conditioning or ceiling fans or are breezy beach fales designed to keep you cool at night.

Hours of Sun in December

December will not disappoint when it comes to the sun. The days are long and hot and the sun rises early in the morning. Early birds will get to do plenty during the cooler morning, while there are ways to cool down by the pool or on the beach when the sun reaches its zenith.

An average day in Samoa in December lasts 13 hours and features up to 6 hours of bright sunshine, usually around midday. Applying sunscreen, wearing sunglasses and a sunhat is a must at this time of the year. Plus, it’s a Christmas look that will make everybody jealous back at the office!

UV Levels During December

UV levels in December are at their highest, peaking at 11+ on the hottest days. Those levels are classified as “extreme” meaning that visitors are advised to apply sunscreen regularly; every couple of hours or after going in the water. For the palest skin, consider investing in UV-protective T-shirts as well – they are a great way to deal with this kind of sun.

We’ve got a lot of information to help you better deal with the Samoa sun. First, a reef-safe sunscreen list that will keep your skin and the amazing coral of the islands safe, and second, a list of the best sunscreen for kids.

Tropical Storms in December

The South Pacific cyclone season starts in November and ends in April, making December a month with a higher risk of tropical storms.

Historically, December has been one of the worst months for cyclones affecting Samoa. Cyclones occurred in December 1831, 1839, 1840, 1842, 1848, 1875, 1890, 1925, 1926, 1930, 1939, 1941, 1946, 1950 and 1962. One of Samoa’s worst recorded cyclones was Cyclone Val (December 1991), which caused 13 deaths and an estimated US$280 million in damage, including homes and agricultural crops.

In more recent times, Cyclone Heta (December 2003) caused isolated flooding, damaged power lines and injured around 20 people. Cyclone Evan (December 2012), however, was more severe, causing 14 deaths and estimated damage of around ST$465 million.

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.

The Best Places to Visit in Samoa in December

Celebrating Christmas is serious stuff for Samoans, so visiting more populated areas, like Upolu, can be a fun experience during this time of the year. On the other hand, Upolu can be busy over the Christmas period, so if you’re looking for tropical tranquillity, head to Savai’i.

Upolu – Upolu is the most popular island to visit in Samoa and more so in December with both locals visiting family and internationals seeking a tropical Christmas. If you enjoy the “buzz” of this time of year combined with a stunning stay in a resort or beach fale, then Upolu is worth considering. Find out more about what Upolu is all about in the 50 Best Things to Do on Upolu.

Savai’i – Swap the buzz of Upolu for Samoa’s less-visited island. Discover historical sites reclaimed by jungles and lava, experience a more traditional slice of life through an array of authentic cultural activities, and hop from one waterfall to the next. See what Savai’i is all about in the 50 Best Things to Do on Savai’i.
