Diving in the Azores is best during the months of June to November but you can actually dive year round in these waters. Good visibility and water temperature is almost always a given. Visibility varies according to the time of the year and the specific weather conditions, but can easily go up to 30 meters. It is best during summer. Throughout the year, the sea temperature varies in between 17° C and 24° C. In winter it is common for the sea temperature to be higher than the air temperature.

Diving in Azores is divided between seamounts and offshore diving in the islands or near islands coast.
