Tonga Weather

This region of the southwest Pacific is typically tropical. You could almost be guaranteed that the temperature will be between 20°C (68°F) and 30°C (86°F) at any time of the day, any day of the year. Humidity is always high but the even temperature and fresh sea breezes means conditions are never too stuffy. Heavy rainfall occurs between October and April, easing off a bit around the middle of the year for some islands while constant for others.
