Measured by satellite

Yesterday, 0.4 mi from La Jolla 73.4 °F

This is the temperature satellites measured yesterday in the water just below the surface, at the nearest point of sea to La Jolla (0.4 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 76.1 °F right now (2.7 °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.
