Is it too cold to swim in Palm Beach?
The latest NASA JPL satellite analysis, dated November 3, 2026, gives 82°F (27.6°C) at the nearest water pixel. That is warm water.
Above 77°F, the temperature below which cold water starts to affect breathing control. Temperature is only one factor: check rip current and surf alerts, and swim near lifeguards.
