The archipelago’s location in the north Atlantic brings it in constant contact with both the high pressure areas common to the North Atlantic and the constantly moving polar and tropical air masses.
As the European continent is over 1500 km away oceanic conditions are the controlling factors of the regional climate. Consequently the Azores has a temperate, maritime climate characterised by agreeable temperatures with small average annual variance.
A high level of humidity (77% average/yr.), and rainfall which is both regular and well distributed throughout the year, although with greater abundance during the winter months, are the dominant weather patterns in the region
Light cloud cover is common throughout the year. The annual median air temperature is approximately 17ºC (63ºF), varying between 13º and 14º C (55º-57ºF) during the colder months (January/February) and 22º-23ºC (72º-73ºF) during the warmer months (July/August). The ocean temperatures oscillate between 14º-15ºC (57º-59ºF) during the coldest month (February) and between 22º-23ºC (72º-73ºF) in August largely due to the warming effects of the Gulf Stream that passes this area.
