Best Time to Dive
Seasonal conditions create a notable contrast for diving at La calanque de Méjean, though scores remain generally "Good" year-round. Peak summer months, from June through August, bring the warmest air temperatures, averaging 23-26°C / 73-79°F, alongside minimal rainfall. This period typically offers calmer surface conditions but can also see increased boat traffic. Conversely, cooler months, November through April, experience air temperatures dropping to approximately 8-15°C / 46-59°F. Rainfall during these months, while still relatively low, occurs more frequently than in summer. Despite colder air, winter diving is feasible and rated "Good", often providing excellent underwater visibility due to less surface activity and fewer particulate matter. Shoulder seasons, like May and September, bridge these conditions with milder weather and good dive scores.
