When to go
Peniche and Berlengas are driven by Atlantic patterns: summer has the most reliable crossings and the warmest water, but upwelling can cool things quickly and wind often strengthens later in the day.
Best overall window
Most reliable island crossings, longest days, and water commonly 16°C to 20°C. Afternoon northerly winds can reach 25 km/h on exposed days.
Outside that window
More frequent Atlantic swell and storms. Expect cancellations for Berlengas boats and limited offshore windows. Water often sits near 14°C to 15°C.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.
