## Conditions at Lamorna Cove

Lamorna Cove is open to the sea from the **E–SW**, so waves build there when the wind blows from those directions.

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

When it's rough here, try [RMS Mulheim](https://scubaforecast.com/scuba-diving-weather/united-kingdom/cornwall/penzance/rms-mulheim) (11 km, sheltered from the E–SSW).

The water stays warm past 18 m.
