Conditions at Large Skerries
Large Skerries is open to the sea from the WNW–ENE, so waves build there when the wind blows from those directions. Land shelters it from the SE–WSW.
Over the next 7 days it's good or better on Sat, Mon and Tue and a no-go on Wed (surge). Thu and Fri are only a trend so far.
The water is 12 °C at the surface and stays warm past 40 m, so a 7 mm with hood, or drysuit suits most dives.
Shelter
Open to WNW–ENE. Waves and swell from there reach the site.
Sheltered from SE–WSW: land blocks the waves.
Computed from the OpenStreetMap coastline. Wind itself is not reduced by shelter.

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.
