Conditions at East Maiden Lighthouse

East Maiden Lighthouse is open to the sea from the NW–SSE, so waves build there when the wind blows from those directions.

Over the next 7 days it's good or better on Sun, Mon and Tue. Thu and Fri are only a trend so far.

When it's rough here, try SS Harrington (9.5 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.

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.
