Located in the Pacific Ocean, the Chatham Islands are exposed, yet still have a temperate climate. Rainfall is around 900mm a year and temperatures vary between 15 - 24 degrees Celsius in summer (December to February) and 6 - 10 degrees in winter. November through April is the best time to visit.
Flying to the Chathams takes about two hours with Air Chathams from Auckland, Wellington or Christchurch.
Chatham Island, the largest of the islands, has a high southern tableland flanked by towering cliffs and a gentle northern portion encompassing extensive waterways, low peat lands and long sandy beaches. The other main island, Pitt, has a heartland of forest and a coast of wild cliffs, headlands and sandy beaches.
The Chatham Islands' long isolation has created a biologically rich environment and presents immense conservation challenges. Many of the local plants and animals are endemic. The vast expanse of ocean that surrounds the islands is rich in marine life with significant populations of seabirds, whales, dolphins and seals. Home to 20% of New Zealand's threatened birds, 14% of threatened plants and 8.5% of threatened fresh-water fish, the Chathams are a place of international importance.
