This is the temperature satellites measured 2 days ago in the water just below the surface, at the nearest point of sea to Illorsuit (0.6 mi away), from NASA's MUR analysis, which sees the water in 1 km detail. It isn't a forecast: the big figure above is what a model gives for right now. On sunny afternoons the top of the water can be a little warmer.
