Conditions at Secca di Washington
Secca di Washington is open to the sea from the NE–ENE, W–WNW, so waves build there when the grecale and ponente blow. Land shelters it from the NNE, SE–S, SW.
Over the next 7 days it's good or better on Sat, Sun and Tue. Thu and Fri are only a trend so far.
When it's rough here, try Grottino di San Francesco (13 km, sheltered from the W–WNW).
The water is 21 °C at the surface and stays warm past 42 m, so a 7 mm or semi-dry suits most dives.
Shelter
Open to NE–ENE, W–WNW. Waves and swell from there reach the site.
Sheltered from NNE, SE–S, SW: land blocks the waves.
Computed from the OpenStreetMap coastline. Wind itself is not reduced by shelter.
