Question: how long does it take to get frostbite in 10 degree weather?
Answer: Frostbite will kick in in under 30 minutes when it's 5 degrees and the wind's blowing at 30mph (producing a "feels like" temp of -19 degrees). Generally speaking, it'll take hours -- if at all -- for frostbite to kick in when the temperature is 10 degrees or higher, no matter the wind speed.
