Conditions at Half Moon Wall

Half Moon Wall is open to the sea from the WSW, WNW–ESE, so waves build there when the wind blows from those directions. Land shelters it from the SE–SW.

Over the next 7 days it's good or better every day. Wed, Thu and Fri are only a trend so far.

The water is 29 °C at the surface and stays warm past 56 m, so a rash guard or 1–2 mm suits most dives.

Shelter

Open to WSW, WNW–ESE. Waves and swell from there reach the site.

Sheltered from SE–SW: land blocks the waves.

Computed from the OpenStreetMap coastline. Wind itself is not reduced by shelter.
