When to go

Best time to visit Algarve (Lagos)

The Algarve is diveable yearround, but conditions feel most forgiving from late spring through early autumn.

Best overall window

June to October

Warmest water, calmer seas, best chance of 12 m to 18 m visibility.

Outside that window

More Atlantic storms and swell; pick sheltered sites and expect cooler water around 15°C to 17°C.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
