## Conditions at Cala Grande

Cala Grande is open to the sea from the **S–SW, W–N**, so waves build there when the tramontana, ostro, libeccio, ponente and maestrale blow. Land shelters it from the NE–SSE.

Over the next 7 days it's good or better every day. Thu and Fri are only a trend so far.

When it's rough here, try [Le Scole](https://scubaforecast.com/scuba-diving-weather/italy/tuscany/giglio/le-scole) (15 km, sheltered from the S–SW, W–NW).

The water stays warm past 38 m.
