Tonga, Tonga

Tonga is one of few places where humpback whales can be swum with by snorkellers, between Vava'u's protected harbour and the Ha'apai atolls' calm channels July through October.

Highlights

When to Visit

Jul-Oct

Humpback whale-swimming season with calves visible on calm days off Vava'u and Ha'apai, and dive operators run multiple trips daily.

May-Jun

Whales arriving and the country in its dry-season calm, with Tongatapu's archaeological sites at the Ha'amonga Trilithon comfortable to explore.

Nov-Apr

Cyclone season with January-March highest risk, whales gone south, and many smaller island lodges close. Tongatapu accessible year-round.

Sep

Whale season at peak with calves at maximum size and confidence, and the Heilala Festival in late June-early July aside, the kingdom is active.
