~9 km model grid; nearest model water 2 km away. Daily averages; the thermocline can move several metres day to day.

Rainbow Reef is open to the sea from the SE–W, so waves build there when the wind blows from those directions. Land shelters it from the NW–ESE.

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

The water is 26 °C at the surface and stays warm past 56 m, so a 3 mm wetsuit suits most dives.

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

Sheltered from NW–ESE: land blocks the waves.

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

Scores are today's best daylight hour.
