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.

Water at depth

19 °C down to about 56 m. No thermocline above that.

Suit: 7 mm or semi-dry for the whole dive.

Conditions at San Carlos Beach

San Carlos Beach is open to the sea from the NNW–NNE, so waves build there when the wind blows from those directions. Land shelters it from the ESE–NW.

Over the next 7 days no day looks good: Sat and Mon are a no-go (waves and surge). Wed, Thu and Fri are only a trend so far.

The water is 19 °C at the surface and stays warm past 56 m, so a 7 mm or semi-dry suits most dives.

Shelter

Open to NNW–NNE. Waves and swell from there reach the site.

Sheltered from ESE–NW: land blocks the waves.

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

About this forecast

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.
