## Conditions at St Brides Haven

St Brides Haven is open to the sea from the **W–NW**, so waves build there when the wind blows from those directions. Land shelters it from the ENE–SW.

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

When it's rough here, try [Dakotian](https://scubaforecast.com/scuba-diving-weather/united-kingdom/pembrokeshire/tenby/dakotian-wreck-milford-haven) (7.5 km, sheltered from the W–NW).

The water stays warm past 29 m.
