Below 32°FBelow 0°CFor swimming this is considered extremely cold. It’s possible you would need to clear surface ice to gain access to the water and unless suitably protected with insulated waterproof clothing hypothermia would very quickly occur.
32 to 46°F0 to 8°CThe river doesn’t freeze, but it can get down to 37 degrees (F) in the dead of winter. For swimming this is considered very cold and is a risk of hypothermia if exposed for any more than a few minutes.
46 to 55°F8 to 13°CThis is the range of temperature in the Spring and Fall. Take note: for swimming this is considered cold and any more than a few minutes in the water will be uncomfortable. Low outside temperatures can quickly get a person into hypothermia danger.
