## Conditions at SS Carmarthen

SS Carmarthen is open to the sea from the **E–SW**, so waves build there when the wind blows from those directions. Land shelters it from the WNW–ENE.

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

The water stays warm past 56 m.
