Just a comment.? I sail in the winter in NC.? Water temp gets to mid to high forties but we? often get days where air temps are?in the low fifties and brisk winds.? I wear a dry suit with?a thermal dry shirt and pants underneath and possibly a tee shirt
with a rain parka on the outside.? Also divers booties.? Even in 15 mph breeze I am very warm.? I do not like to be cold and do not tolerate it well.? I chose the dry suit to prevent hypothermia in the event I get dunked and it is quite flexible and comfortable.?
I also for safety reasons carry a portable waterproof VHF radio as well as a cell phone.? Not many boats out there to help you like summertime if for some reason I couldn’t right the boat or had a breakdown.? You have about an hour or less in that temp water
before you become incapacitated.
If you are sailing on a day where the thermometer reads 50°, and the wind is blowing a steady 15 MPH, the wind chill will make it feel like it is 36° (heat will be lost as though you are standing outside on a calm 36° day).? There are no hard and fast rules
when it comes to choosing which wetsuit to wear when it comes to wind chill.? Just remember, the higher the sustained wind speeds are on the water, the thicker and warmer your wetsuit needs to be that day.
In addition to water and air temperatures consider the following:
Your sensitivity to getting cold
How active you will be
Note: For colder than water air temperatures, higher wind, less active sailing, or if you get cold easily, consider a thicker wetsuit
