The Climate in Tonga
Tonga’s climate is warm, tropical and welcoming. Temperatures are warm all year round and can get hot in the summer, but seldom reach above 35°C (95°F). Trade winds from the East-Southeast bring year-long cooling breezes in the late afternoon and early evening. Tropical rains fall from December through February, coinciding with the warmest summer months. However, there are no significant differences in temperatures between summer and winter. In general, the winter temperatures (April to September) are only slightly cooler than summer temperatures (November to February).
Required clothing:
Modest dress is necessary for both Tongans and visitors. Allowances are made for tourists at beaches while many Tongans are conservatively covered while swimming.
