Tonga in September

Mothers and calves in the bays; still dry and busy.

• Tongatapu and 'Eua · Nuku'alofa, the south coast, 'Euabest weather

  Southernmost group: Jun–Aug nights can drop to about 16 °C, and the trade winds make it pleasant. Dec–Mar is humid with heavy showers and cyclone risk.

• Ha'apai · Lifuka, Foa, Uolevabest weather

  Low coral islands with little shade; the whole group is exposed to storms and to tsunamis.

• Vava'u · Neiafu and the island mazebest weather
