## Conditions at Chesil Cove

Chesil Cove is open to the sea from the **SSW–WNW**, so waves build there when the wind blows from those directions. Land shelters it from the NNW–S.

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

When it's rough here, try [The Dredger](https://scubaforecast.com/scuba-diving-weather/united-kingdom/dorset/weymouth/the-dredger-portland) (2.3 km, sheltered from the SSW–WNW).

The water stays warm past 29 m.
