~9 km model grid; nearest model water 0.6 km away. Daily averages; the thermocline can move several metres day to day.

Fantasea Reef is open to the sea from the E–W, so waves build there when the wind blows from those directions. Land shelters it from the WNW–NNE.

Over the next 7 days no day looks good: Sun and Mon are a no-go (gusts). Wed, Thu and Fri are only a trend so far.

The water is 26 °C at the surface and warm to about 54 m, so a 3 mm wetsuit suits most dives.

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

Sheltered from WNW–NNE: land blocks the waves.

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

Scores are today's best daylight hour.
