The climate is oceanic and thus rainfall is more important than temperature. Nevertheless, the extent of the islands stretching over 200 of latitude (between 80s and 280s) and the size and character of the relief introduce local climatic variations. Two seasons can be distinguished: warm and wet 2. Population from November to April, relatively cold and dry from May to October.

This improvement in employment is due to the economic development of the territory, soaring I I urbanization and the growth of tourism.
