This is the temperature satellites measured yesterday in the water just below the surface, at the nearest point of sea to St. George's (0.9 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.
