Is it too cold to swim in Destin?
The latest NASA JPL satellite analysis, dated November 4, 2026, gives 75°F (24.1°C) at the nearest water pixel. That is mild water.
Between 70°F and 77°F: above the 70°F level where the National Center for Cold Water Safety recommends thermal protection, though below 77°F cold can start to affect breathing control. Temperature is only one factor: check rip current and surf alerts, and swim near lifeguards.

Where does this water temperature come from?
We show NASA JPL’s daily MUR satellite analysis for the nearest water, about 0.2 mi away, when no suitable current in-water sensor is available. Satellite values are typically a degree or two cooler than afternoon readings at the shore. Satellite vs. buoy temperatures.
