What is the Weather Like in Samoa in August?

There’s a reason why Samoa is such a popular holiday destination in August. For Americans, Samoa’s warm weather and soothing sea breeze offer relief from the Northern Hemisphere summer, while Australians and New Zealanders can escape the winter. Incidentally, August is also one of the busiest months in Samoa. Even if it is a little busier in Samoa during August, the allure of the warm sunny days, warm sea temperatures and awesome conditions for snorkelling, scuba diving and surfing understandably might draw you in regardless. If that’s the case, take a look at our guide to the Samoa weather in August.

Before we jump into this weather guide for August, be sure to bookmark Samoa Weather, Seasons & Climate + Samoa Weather by Month, as well as The Best Time to Visit Samoa: A Month-by-Month Guide for more advice.

5 Tips for Visiting Samoa in August

  1. August is one of the most popular months to visit Samoa, so book flights and accommodation well in advance to avoid disappointment (with the exception of beach fales, who are sometimes easiest to book just a day or two in advance with a quick phone call)
  2. The water visibility is at its best in August, so pack your snorkel mask or book that dive trip
  3. UV levels are high, so be sure to apply high-factor reef-safe sunscreen regularly
  4. Note that the Monday after the second Sunday in August is Father’s Day in Samoa, a public holiday where some businesses are closed (natural attractions tend to still be open, however)
  5. Note that if it has been a particularly dry season, some waterfall attractions may be dried up – see which ones are sometimes at risk in the 10 Best Waterfalls in Samoa.

Typical Temperatures in August

Temperatures might be at their lowest in Samoa during August, but they hardly deviate from summer temperatures with highs averaging at 29°C / 84°F. Although the evenings are cooler, they are still a comfortable average of 23°C / 73°F.

Humidity balances between moderate and high, which feels like a warm tropical hug but most don’t find it too humid during this time. Sea temperatures are at their coldest of the year but, again, they are only marginally cooler than summer – still totally swimmable!

Hours of Sun in August

The great thing about Samoa in winter is that the days are relatively long and sunny. The average hours of daylight are 12 hours per day, while sunshine hours are usually around 8 hours. In short, this makes August one of the sunniest months in Samoa on average. Get to the beach (and don’t forget to pay your entry fees)!

UV Levels During August

After usually experiencing lower UV levels in the previous two months, Samoa’s UV levels start to rise again in August. The UV level in August is typically around 10 UV index around midday, which is very high. It’s a good idea to apply high-factor sunscreen throughout the day. For advice on what sunscreen to wear, that’s safe for you and the reefs, see The Best Sunscreens for Samoa + Sun Protection Tips.

Sunrise and Sunset During August

August has daylight hours lasting about 12 hours a day in Samoa.

  • Sunrise: 06.48 am at the beginning of August and 6.33 am at the end of August

The Best Places to Visit in Samoa in August

Both of Samoa’s two main islands are ideal to visit in August, so be sure to compare them both in The Best Islands to Visit in Samoa. If you only have time to visit one, however, we recommend travelling to the island less visited during this busier time of year, Savai’i.

For South Seas tranquillity, opt for Samoa’s less-visited island just across the pond from Samoa’s international airport. Discover historical sites reclaimed by jungles and lava, experience a more traditional slice of life through an array of authentic cultural experiences, 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.

That’s not to say that Samoa’s main island, Upolu shouldn’t be on your bucket list. If you have more time, we highly recommend taking the extra time to explore its awesome natural and cultural wonders.

August Packing List for Samoa

Be prepared for Samoa in August by packing these few seasonal essentials:

  • Light clothing layers for the day (preferably linen, bamboo or merino so it is super light – we like the sustainable bamboo clothing of Moso Morrow)
  • Light long-sleeved tops (to cover from sun and mosquitoes)
  • Light pants/trousers/skirt (to cover the knees when appropriate – villages, church services or to protect from mosquitoes when hiking, for example)
  • Sunhat
  • Sunglasses
  • Swimwear
  • Rash vest (we like the UV-protecting Sharkskin rashies)
  • Closed walking shoes
  • Flip-flops/jandals/sandals
  • Sarong (lavalava – you can always buy one once you arrive in Samoa at The Best Places to Buy Souvenirs)
  • Insect repellent
  • High-factor sunscreen (that’s reef-safe and water-resistant).
