The climate of Pitcairn

The Pitcairn Islands, a group of four volcanic islands, are located in the southern Pacific Ocean, the only inhabited island being Pitcairn Island itself. The isolation and location of these islands play a significant role in shaping their unique tropical rainforest climate.

Throughout the year, the islands experience consistently high temperatures, with average monthly temperatures invariably above 18°C (64.4°F). This uniformity in temperature is due to their equatorial positioning, resulting in minimal temperature fluctuations between seasons. Precipitation is substantial, presenting no distinct dry season, another characteristic feature of tropical rainforest climates. This heavy rainfall, averaging 1700mm (66.93") annually, combined with the high temperatures, creates a humid environment.
