Conditions at Isle of Muck North

Isle of Muck North is open to the sea from the NW–SSE, so waves build there when the wind blows from those directions. Land shelters it from the S–W.

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

When it's rough here, try SS Harrington (4.5 km, sheltered from the ENE–SSE, NW).

The water is 13 °C at the surface and stays warm past 56 m, so a 7 mm with hood, or drysuit suits most dives.

Shelter

Open to NW–SSE. Waves and swell from there reach the site.

Sheltered from S–W: land blocks the waves.

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

About this forecast

Updated Sat 14 Nov, 15:30 · weather run 06Z 14 Nov · waves run 00Z 14 Nov

Waves are adjusted for this site's shelter from the coastline.

Tides come from a coarse ocean model. The range, and whether tides are bigger or smaller this week, are about right. Times are usually within about half an hour, but complex tides (the Solent, Portland, narrow straits) are poor. Slack water isn't in the score yet: plan with official tide tables and local advice.
