Geography & environment

Landscape

Tonga is an island kingdom containing both low coral islands and high volcanic islands. Tongatapu, the main population centre, is relatively low and limestone-based. Other groups have different relief and more deeply indented coastlines.

Vava‘u includes raised islands and sheltered waterways, while the western island chain includes active volcanoes. These contrasting settings influence settlement, water supplies and coastal access. The islands are spread over a long north-to-south distance.

Climate & seasons

Ocean winds moderate the tropical climate. Summers are warmer and generally wetter, while winters are cooler and drier.

Island hazards & habitats

Reefs, lagoons and coastal vegetation support important habitats. Low islands face different freshwater and storm risks from high volcanic ones. Volcanic activity and tsunamis are also significant features of Tonga’s regional setting.

Full control of external affairs returned in 1970. Political reforms in 2010 increased the number of popularly elected seats and changed how the Prime Minister is chosen.
