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

21 °C at the surface, warm to about 34 m.

Suit: 7 mm or semi-dry down to ~34 m.

~9 km model grid; nearest model water 4.6 km away, so channels and bays may differ. Daily averages; the thermocline can move several metres day to day.

Conditions at Shelly Beach

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

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

When it's rough here, try North Bondi (10 km, sheltered from the NNE–E).

The water is 21 °C at the surface and warm to about 34 m, so a 7 mm or semi-dry suits most dives.

Shelter

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

Sheltered from ESE–NNW: land blocks the waves.

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

About this forecast

Updated Sun 15 Nov, 02:30 · 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.
