Frostbite can set in within a matter of a few minutes to a few hours, depending on conditions in addition to the ambient temperature and windspeed, factors such as: degree of exposure, wet vs. dry skin, and the degree of circulation in the area in question. Windchill is of chief concern, as high winds dramatically increase the rate of heat loss from exposed areas.
At any temperature near or below freezing, the human body automatically shunts blood flow away from the extremities to preserve core temperature (and help prevent hypothermia). Fingers, toes, nose, cheeks, and ears are the most at-risk areas.
Those with medical conditions such as Diabetes that reduce circulation in the extremities in particular face an increased risk.
Also, tight or restrictive clothing can be problematic. Wearing too many layers of socks inside one's boots, for example, is a common mistake leading to further reduction of bloodflow to feet and toes. The increased insulation is of little value once new heat is no longer flowing from the body's core.
Initial symptoms of first-degree frostbite include itching, pain, and eventual numbness in the exposed area; as well as yellow, white, or red patches of skin.
Caution should be exercised any time temperatures are near or below freezing (32 degrees Fahrenheit or 0 degrees Celsius), particularly in windy and/or damp conditions.
Very cold. -30 c = -22 f
In 30-degree weather, it can take about 30 minutes to get frostbite on exposed skin.
Roughly 9 minutes to exposed skin, assuming there is strong wind.
Frostbite can occur in temperatures around 0 degrees Fahrenheit within 30 minutes to an hour, depending on factors such as wind chill, moisture, and individual susceptibility. Exposed skin, especially extremities like fingers and toes, is particularly vulnerable. Wind can significantly accelerate the onset of frostbite, making it possible to develop it even faster in windy conditions. It's crucial to monitor for signs of frostbite and take precautions in such cold weather.
In 10-degree weather, it can take as little as 30 minutes to get frostbite on exposed skin.
Skin can freeze in as little as 30 minutes when exposed to -20 degrees Fahrenheit. At extremely cold temperatures like this, it is important to limit exposure to avoid frostbite and other cold-related injuries.

Frostbite can occur in as little as 30 minutes at temperatures below 0F (-18C), but it can happen faster in even colder temperatures. It's important to protect exposed skin in extreme cold to prevent frostbite.
Frostbite can lead to various health risks depending on the severity. Mild frostbite may cause numbness and tingling, while severe frostbite can result in tissue damage, infection, and even amputation. In extreme cases, frostbite can lead to permanent nerve damage and long-term complications. It is important to seek medical attention promptly to prevent further complications.
