Measured by satellite
This is the temperature satellites measured yesterday in the water just below the surface, at the nearest point of sea to Fundy-St. Martins (0.5 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.
Big gap with the model, which gives 51.4 °F right now (2.9 °F lower). The forecast is a calculation and this is a measurement: the water is probably warmer than the model says.
