## Conditions at Eddystone Reef

Eddystone Reef is open to the sea from the **NNE–NNW**, so waves build there when the wind blows from those directions.

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

When it's rough here, try [Fort Bovisand](https://scubaforecast.com/scuba-diving-weather/united-kingdom/devon/plymouth/fort-bovisand) (20 km, sheltered from the NNE–SSE, NNW).

The water stays warm past 47 m.
