Best Time to Dive

Air temperatures rise from 12.5°C (54°F) in April to a peak of 24.5°C (76°F) in July, providing comfortable surface conditions for divers.

Rainfall patterns, averaging 3-4 mm per month during these peak seasons, usually don't significantly impact visibility. While specific water temperature data isn't consistently reported, the site's shallow nature implies quicker warming during the summer, offering pleasant water conditions for extended periods. Dive scores indicate "Good" conditions from February through November, suggesting ample opportunities throughout much of the year, with less favorable but still "Good" scores in winter months.
