The heaviest coatings of frost usually do not occur at the coldest temperatures because very cold air can not hold very much water vapor. Instead, thick deposits of frost usually occur when the air temperature is close to 32 deg.F (0 deg.he heaviest coatings of frost usually do not occur at the coldest temperatures because very cold air can not hold very much water vapor. Instead, thick deposits of frost usually occur when the air temperature is close to 32 deg.
As the air temperature approaches freezing, the surface temperature of plants can dip below freezing, causing ice crystals to form in the same manner that dew forms on warmer nights. Because temperatures vary just a few feet above the ground, frost can form when your thermometer reads above freezing.
