## Conditions at HMS Drake

HMS Drake is open to the sea from the **W**, so waves build there when the wind blows from those directions. Land shelters it from the WNW–SSE.

Over the next 7 days it's good or better on Sun, Mon and Tue. Thu and Fri are only a trend so far.

When it's rough here, try [SS Templemore](https://scubaforecast.com/scuba-diving-weather/united-kingdom/county-antrim/ballycastle/templemore-ballycastle) (8.5 km, sheltered from the W).

The water stays warm past 34 m.
