How this page works
The temperature now and the next days are the sea surface temperature from the Open-Meteo Marine API (ocean and wave models of Copernicus Marine, Météo-France and ECMWF) at the sea point off Bells Beach, fetched in your browser; waves are the significant wave height and peak period from the same API. The monthly averages are NOAA OISST v2.1 1991–2020 long-term means. The map is the sea surface temperature layer (NASA JPL GHRSST MUR via NASA GIBS).
