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.

Conditions at Cook Island

Cook Island is open to the sea from the NNW–SSE, so waves build there when the wind blows from those directions. Land shelters it from the SSW–WNW.

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

The water is 23 °C at the surface and warm to about 10 m, so a 5 mm wetsuit suits most dives.

Shelter

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

Sheltered from SSW–WNW: 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.
