When is it safe to go?

It's official. Spring is here. The water is cold, but in my opinion, it's safe to go. Last week on Lake Phalen, the temperature of the water was 53. That's pretty good.

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.

Hypothermia Chart
IF THE WATER TEMPERATURE (F) IS:EXHAUSTION OR UNCONSCIOUSNESSEXPECTED TIME OF SURVIVAL IS:
32.5Under 15 MinutesUnder 15 - 45 Minutes
32.5 - 40.015 - 30 Minutes30 - 90 Minutes
40.0 - 50.030 - 60 Minutes1 - 3 Hours
50.0 - 60.01 -2 Hours1 - 6 Hours
60.0 - 70.02 - 7 Hours2 - 40 Hours
70.0 - 80.03 - 12 Hours3 Hours - Indefinitely
OVER 80.0IndefinitelyIndefinitely

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!
