The wind often blows, moderate or strong, especially in winter, when weather fronts brought by the westerlies often pass at this latitude, and there are periods of bad weather.
The amount of sunshine is high in the summer months, and is still acceptable in the winter months, when there are also sunny days.
Adamstown, the capital, is located in the only inhabited island, the southernmost of the four islands of the archipelago, in which the descendants of the Bounty mutineers reside.
The Pitcairn Islands can be brushed, though rarely, by tropical cyclones, usually not intense because the waters in which they are located are not warm enough, and therefore do not provide a lot of energy. This happens from November to April.



The sea temperature is high enough in summer, while from July to October it becomes a little cool for swimming.

The best time to visit the Pitcairn Islands runs from January to March, being the warmest and sunniest, and also the best for swimming and sunbathing. Sometimes, however, in this period tropical cyclones may pass, or rather their remains. You can therefore come in the other months, particularly in September and October, when, however, the weather is a bit cool for swimming.


In winter (June to August): spring/autumn clothes, light for the day, sweatshirt or sweater, jacket, raincoat or umbrella.
In summer (December to February): light clothes for the day, a scarf for the breeze, a sweatshirt for the evening, light raincoat or umbrella.
