Mangaia's Tropical Climate

Understanding the tropical maritime climate of Mangaia

Mangaia enjoys a tropical maritime climate characterized by constant temperatures and refreshing trade winds. The raised island influences rainfall, creating microclimates based on altitude and exposure to prevailing winds.

The island features a drier, windier coastal zone, while the slightly elevated interior receives more precipitation. Southeast trade winds dominate, bringing coolness and humidity.
