Samoa’s climate is dictated by its position in the South Pacific near to the Equator. As with many of the South Pacific island nations, it experiences a distinct wet season between November and March. The weather is drier from April to October, but it does tend to be fairly hot and humid most of the year. Average daily temperatures hover around 28-30°C (84-86°F) and the seawater is balmily warm. As both of Samoa’s main islands are mountainous, you’ll often see the interiors shrouded in low cloud. As a general rule, more rain falls on the islands’ southern flanks.

Samoa has a warm tropical climate, similar to that of it’s bigger island neighbour, Fiji. Visitors should expect mid to high 20’s year round, with higher humidity during the wet season that runs from Mid-November to the end of April. Cyclonic events can occur during the wet season so we recommend travel during the dry season which is May through to mid-November. For the laidback experience that Samoa is famed for it is best to also consider avoiding the New Zealand and Australian school holidays which vary year on year.

Visiting Samoa in June - September

This is the best time of year to visit Samoa if you want to be virtually guaranteed warm weather with the least chance of rain. It’s an ideal time for snorkeling, swimming and relaxing on the beaches. Be aware that this period is also the islands’ busiest time, as they see an influx of visitors from New Zealand and Australia, who come here to escape the southern hemisphere winter.

Events & Festivals

  • Samoa’s Independence Day is celebrated at the beginning of June, with celebrations across the islands.
  • Apia’s Teuila Festival, a week-long music, sport and dance event, takes place in early September.
