2 days ago, 0.2 mi from Granity 59.5 °F

This is the temperature satellites measured 2 days ago in the water just below the surface, at the nearest point of sea to Granity (0.2 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.
