~9 km model grid; nearest model water 2.7 km away. Daily averages; the thermocline can move several metres day to day.
Shark’s Mouth is open to the sea from the SSW–NNW, so waves build there when the wind blows from those directions. Land shelters it from the N–SE.
Over the next 7 days it's good or better every day. Wed, Thu and Fri are only a trend so far.
The water is 30 °C at the surface and warm to about 50 m, so a rash guard or 1–2 mm suits most dives.
Open to SSW–NNW. Waves and swell from there reach the site.
Sheltered from N–SE: land blocks the waves.
Computed from the OpenStreetMap coastline. Wind itself is not reduced by shelter.
