Measured by satellite

2 days ago, 0.6 mi from Port Germein 67.3 °F

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

Big gap with the model, which gives 70.2 °F right now (2.9 °F higher). The forecast is a calculation and this is a measurement: the water is probably colder than the model says.

A rough guide: it depends on the wind, how long you stay in and each person.

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.
