Launching on Lake Phalen |
Hypothermia is always a concern. In the off chance that you find yourself in the water, you have a limited amount of time to get out. This chart may help you decide when it's safe to launch.
IF THE WATER TEMPERATURE (F) IS: | EXHAUSTION OR UNCONSCIOUSNESS | EXPECTED TIME OF SURVIVAL IS: |
32.5 | Under 15 Minutes | Under 15 - 45 Minutes |
32.5 - 40.0 | 15 - 30 Minutes | 30 - 90 Minutes |
40.0 - 50.0 | 30 - 60 Minutes | 1 - 3 Hours |
50.0 - 60.0 | 1 -2 Hours | 1 - 6 Hours |
60.0 - 70.0 | 2 - 7 Hours | 2 - 40 Hours |
70.0 - 80.0 | 3 - 12 Hours | 3 Hours - Indefinitely |
OVER 80.0 | Indefinitely | Indefinitely |
Conditions get safer after the water temp climbs above fifty, but that's not the only factor. General weather conditions are also to be considered. Sunny is safer. Air temperature of sixty or more is best. Wind speeds below ten MPH will be good.
So, wait for a good day. Stay close to shore and have a life jacket handy or on. Enjoy yourself!
