Tonga Climate & Weather
Despite the huge distance from the north of the country to the south, the climate in Tonga is relatively steady, with only mild differences in temperature between the warm Vava'u and Niuas and the noticeably cooler Eua. The climate in Tonga is divided between the dry season (May to October) and the wet season (November to April), with temperatures maintaining an average of 78°F (26°C) throughout the year. March is the wettest month in Tonga, and most rain falls at night, with hot, humid days. Tropical storms in Tonga are most likely to occur between November and March. The best time to travel to Tonga is during the dry season, when most of the festivals are held. While prices generally stay steady throughout the year, tourists travelling to Tonga in the December to January holiday period should book flights and accommodation well in advance.
