Measured by satellite
This is the temperature satellites measured 2 days ago in the water just below the surface, at the nearest point of sea to Asakuchi (2.9 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.
Big gap with the model, which gives 71.6 °F right now (3.1 °F lower). The forecast is a calculation and this is a measurement: the water is probably warmer than the model says.

Fish are cold-blooded: the water sets their activity. Sudden temperature changes usually put them off the bite; with steady water, activity is more regular.
