## 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](https://scubaforecast.com/scuba-diving-weather/italy/sardinia/la-maddalena/grottino-di-san-francesco) (13 km, sheltered from the W–WNW).

The water stays warm past 42 m.
