The weather is influenced by the Azores High. Its location, intensity and orientation strongly determine the islands’ specific conditions.

When to Go

The Azores is a year-round destination as temperatures remain mild even in winter. Actually, the islands have one of the warmest winters in Europe, and summers are never too hot. However, for outdoor activities such as hiking, it is best to choose the spring and summer months when the chances of experiencing rain and storms are slight, and the winds that brush across the islands become weaker.

To enjoy the flowers, spring might be the ideal time. To dive, however, the best time might be summer. In particular, September and October offer the best visibility conditions, and the sea temperature is 24ºC (75ºF) or higher.
