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 Aragusuku Ryugu no Ne

Aragusuku Ryugu no Ne is open to the sea from the NE, SE, SSW–W, so waves build there when the wind blows from those directions. Land shelters it from the ENE–ESE, SSE–S.

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 Kohama West Suzumedai House (14 km, sheltered from the SE, WSW–W).

The water is 27 °C at the surface and stays warm past 29 m, so a 3 mm wetsuit suits most dives.

Shelter

Open to NE, SE, SSW–W. Waves and swell from there reach the site.

Sheltered from ENE–ESE, SSE–S: land blocks the waves.

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

About this forecast

Updated Sun 15 Nov, 00:30 · 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.
