Portugal Weather for Cruisers

The climate is mild and varies slightly, being cooler in the north and warmer in the south.

The prevailing winds of summer are northerly. The Portuguese trades commence in about April and last until September. On the Algarve coast, the northerly winds of summer are often replaced by land and sea breezes. Most gales occur in winter when the prevailing winds are westerly.

Due to their location, some harbours are inaccessible in strong onshore winds and/or southerlies. Great care should be taken when transiting/cruising this coast, especially when large waves and winds are forecast. Monitor the state of harbour entrances (continually updated) along the coast using the following website:

National Maritime Authority (go to "Estado das Barras")

Strong afternoon winds are typical on this coast and it is wise to shorten sail when entering ports or coming south of steep headlands.

Fog is common during the summer months, although it generally disappears by mid-morning.
