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.

26 °C down to about 56 m. No thermocline above that.

Suit: 3 mm wetsuit for the whole dive.

Model estimate (Copernicus Marine), updated Sat 14 Nov. High confidence.

Temperature profile and next days

~9 km model grid; nearest model water 1 km away. Daily averages; the thermocline can move several metres day to day.

Yo-257 is open to the sea from the ESE–W, so waves build there when the wind blows from those directions. Land shelters it from the N–E.

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

The water is 26 °C at the surface and stays warm past 56 m, so a 3 mm wetsuit suits most dives.

Open to ESE–W. Waves and swell from there reach the site.

Sheltered from N–E: land blocks the waves.

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

Scores are today's best daylight hour.
