Natural environment

 

The Norfolk Island group provides an important link between tropical and temperate oceanic island environments. Their isolation and climate make them important habitats for breeding areas for migratory seabirds, and as important refuges for endemic animals and plants.

Climate

Norfolk Island is characterised by a pleasant maritime climate. Summer temperatures range from about 22°C in the morning to 26°C in the afternoon and in winter from about 13°C to 18°C. Rainfall is greatest during the four months from May to August, with monthly long-term means of about 140 to 159 mm. Minimum monthly rainfall, averaging 70 to 90 mm occurs from November to January. The annual mean rainfall is 1328 mm.

Thunderstorms are most prevalent during the winter months and early spring. Hail occasionally accompanies thunderstorms in winter. Cyclones are most frequent in the early months of the year. Mid latitude cyclones move in from the Australian continent or southwest Tasman Sea and effect the island mostly from February to August.
