This high rainfall does not necessarily mean continuous downpours; instead, it often translates to frequent rain showers interspersed with periods of sunshine.
In terms of geographical variation, the climate across the Pitcairn Islands is fairly consistent due to their small size. The only inhabited island, Pitcairn Island, does not have significant climatic differences across its area. However, the topographical variation could lead to microclimates where some higher-altitude areas may be slightly cooler and receive marginally more rainfall.
