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 40 m. No thermocline above that.

Suit: Rash guard or 1–2 mm for the whole dive.

Conditions at Tanote Bay

Tanote Bay is open to the sea from the ENE–S, so waves build there when the wind blows from those directions.

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 Mae Haad (3.0 km, sheltered from the ENE–S).

The water is 30 °C at the surface and stays warm past 40 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: 0.1 km of open waterNNE: 0.1 km of open waterNE: 0.0 km of open waterENE: open sea (over 200 km)E: open sea (over 200 km)ESE: open sea (over 200 km)SE: 22.0 km of open waterSSE: 35.1 km of open waterS: 92.0 km of open waterSSW: 0.3 km of open waterSW: 0.1 km of open waterWSW: 0.1 km of open waterW: 0.2 km of open waterWNW: 0.2 km of open waterNW: 0.2 km of open waterNNW: 0.1 km of open waterNESW

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

Sheltered from SSW–NE: land blocks the waves.

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

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.
