Waves and swell are adjusted for this site's shelter from the coastline. Arrows point where the wind and swell go. Night hours are shaded. Tide times come from an ocean model: usually within about half an hour, more in complex waters. Check official tide tables.

Conditions at SS Harrington

SS Harrington is open to the sea from the NNW–NE, so waves build there when the wind blows from those directions. Land shelters it from the ENE–S, SW–NW.

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

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 NNW–NE. Waves and swell from there reach the site.

Sheltered from ENE–S, SW–NW: 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.
