Samoa has a tropical climate with consistently warm temperatures year-round, averaging 26-30°C (79-86°F) at sea level. The country experiences two distinct seasons: a dry season from May to October with lower humidity, lower rainfall, and pleasant trade winds, and a wet season from November to April bringing heavy tropical downpours, high humidity, and cyclone risk. Despite the wet season label, rain typically falls in intense afternoon bursts rather than all-day grey skies.
