Best time to snorkel in Sardinia

The seasonal pattern for Sardinia — what each stretch of the year tends to bring, and what to plan around. Guidance, not a forecast.

Seasonal pattern, not a forecast — conditions vary; verify tides, weather and visibility locally before you go.

The seasonal pattern

Aim for late spring through early autumn for warm water and calm, settled seas; summer is peak season in the north-east, so the quieter west and the park's off-peak hours are the escape valve. The Maddalena archipelago is a regulated national park, so do the boat day with a licensed operator who knows the anchoring rules. Keep off the posidonia seagrass and the coral, and follow local access guidance at the grottoes. Your own mask and fins and a calm morning start will get you the clearest water.
