The small size of the island of Formentera, as well as its low relief, means its climatic characteristics vary very little from one place to another. Despite this, there are small variations, largely the temperature and humidity, between the lower parts of the island and the Miocene promontories of La Mola and Cap de Barbaria.

However, in general, the characteristic climate of the island is typically Mediterranean, and it can be included in the climate type with temperate/warm domination. Within this variety, the island would be climatically included in the Levantine/Balearic sub-variety.

During the summer, Formentera, in the same way as the rest of the Western Mediterranean, remains to the east of the Azores anticyclone. This means the highest pressure values are due to this anticyclone extending towards the east. This situation is most common in summer, producing maximum temperatures and less rainy periods.

On the other hand, in winter, because the Atlantic high pressure areas are much further south, cyclonic activity usually fully affects Formentera's climate, bringing rain and fronts towards it.

However, Formentera is the Balearic Island with the warmest and least rainy climate.
