Every dive offers another opportunity to discover the extraordinary biodiversity of Portugal's Atlantic waters!

5. The Geological Beauty of the Berlengas

One of the archipelago's most fascinating characteristics is its dramatic rocky landscape.

6. When Is the Best Time to Dive the Berlengas Islands?

Diving conditions are influenced by Atlantic weather, swell, currents, and seasonal water temperatures.

The main recreational diving season generally extends from late spring through early autumn.

Season	General Diving Conditions
December – February	Cooler water and potentially challenging Atlantic conditions
March – May	Improving weather, although sea conditions remain variable
June – August	Popular diving season with longer daylight hours
September – October	Often attractive diving opportunities when weather permits
November	Cooling conditions and more variable swell

Typical water temperatures may range from approximately 55°F to 70°F (13–21°C), depending on season, depth, and oceanographic conditions.

Visibility varies significantly and may range from approximately 15 to 65 feet (5–20 meters) or more during favorable conditions.

The Atlantic Ocean can produce strong currents, swell, and rapidly changing weather.

For many recreational divers, June through September offers an attractive planning window.

However, dive operators may cancel trips when sea conditions are unsuitable.

7. Is Berlengas Diving Suitable for Beginners?

The Berlengas Islands offer diving experiences for different skill levels, depending on the dive site and conditions.

Some sheltered locations may be suitable for newly certified divers under appropriate supervision.
