Is it too cold to swim in Lake Texoma?
The latest NASA JPL satellite analysis, dated November 3, 2026, gives 70°F (21.1°C) at the nearest water pixel. That is cold water.
Between 60°F and 70°F, which the National Center for Cold Water Safety rates as dangerous. It recommends a wetsuit or drysuit below 70°F. Temperature is only one factor: check rip current and surf alerts, and swim near lifeguards.
