## Conditions at Grotta di Nereo

Grotta di Nereo is open to the sea from the **SE–NNW**, so waves build there when the scirocco, ostro, libeccio, ponente and maestrale blow. Land shelters it from the N–E.

Over the next 7 days it's good or better on Mon and Tue and a no-go on Wed (waves). Thu and Fri are only a trend so far.

The water stays warm past 23 m.
