## Conditions at Lydstep Haven

Lydstep Haven is open to the sea from the **E, SE–S**, so waves build there when the wind blows from those directions. Land shelters it from the SSW–ENE.

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

The water stays warm past 8 m.
