Tonga Travel Guide


The name Tonga means south; it's refreshingly cooler and less humid here than on islands closer to the equator (such as sultry Samoa).

December-April is the hot, rainy season, with especially high humidity January-March.

June-August can be cool enough to make a sweater occasionally necessary.

Tonga gets an average of two tropical hurricanes a year, usually between November and April, although they can occur as late as May.

Rainfall, temperatures, and the probability of hurricanes increase the farther north you go.

The southeast trade winds prevail May-November, and easterlies the rest of the year.

In Tonga, west and northwest winds herald bad weather.

In February and March, north winds bring heat waves and heavy rains.
