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

30 °C down to about 34 m. The model's water ends there; nothing is known below.

Conditions at Red Rock

Red Rock is open to the sea from the WNW–ENE, so waves build there when the wind blows from those directions. Land shelters it from the E–SE, SSW–W.

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

When it's rough here, try Tanote Bay (5.6 km, sheltered from the WNW–NE).

The water is 30 °C at the surface and stays warm past 34 m, so a rash guard or 1–2 mm suits most dives.

Shelter

Open water in each direction from the site. Longer petals mean more open sea, so more exposure to wind waves and swell from that direction.N: 183.1 km of open waterNNE: open sea (over 200 km)NE: open sea (over 200 km)ENE: open sea (over 200 km)E: 0.9 km of open waterESE: 0.9 km of open waterSE: 0.9 km of open waterSSE: 3.6 km of open waterS: 4.8 km of open waterSSW: 0.3 km of open waterSW: 0.3 km of open waterWSW: 0.2 km of open waterW: 0.3 km of open waterWNW: 67.4 km of open waterNW: 67.6 km of open waterNNW: 89.1 km of open waterNESW

Open to WNW–ENE. Waves and swell from there reach the site.

Sheltered from E–SE, SSW–W: land blocks the waves.

About this forecast

Updated Sat 14 Nov, 22:30 · 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.
