Weather and Climate in Samoa

Understanding the tropical oceanic climate of Samoa

Samoa enjoys a tropical oceanic climate with two distinct seasons. The Pacific Ocean regulates temperatures, while trade winds provide cooling breezes and variable rainfall depending on the island's exposure.

Northern coastal zone: Drier and sunnier, protected from prevailing winds
Southern coastal zone: More humid with frequent rainfall and lush vegetation
