Tonga weather overview
Tonga comprises three groups of islands situated southeast of Fiji. These islands share a tropical oceanic climate, which means high temperatures and rain year round, with heaviest downpours occurring between December and April - the hottest and most humid months of the year. However, sea breezes modify humidity along the islands' coasts.
Although heavy cloud cover can mean a few miserable days in the wettest periods, this is comparatively rare. Generally speaking, the islands enjoy frequent bouts of strong sunshine between rain showers.
