Can you get frostbite above freezing?
The air temperature has to be BELOW freezing for frostbite to develop on exposed skin. Wind chill can NOT bring the temperature to below freezing for humans and animals when the thermometer says it is above freezing so you will not get frostbite; however, you might get hypothermia from exposure to cold.
Can you get frostbite in 5 minutes?

Can you get frostbite at 32 degrees?
Frostbite is injury to the skin resulting from freezing of the tissue. It occurs only with air temperatures below freezing (below 32 degrees). But it’s not that simple because evaporative cooling (the chill that occurs when water evaporates from a wet surface) is a factor.
How long does frostbite take to heal?
If the frostbite is superficial, new pink skin will form beneath the discoloured skin and scabs. The area usually recovers within 6 months.
