Estimate relative cold exposure and hypothermia risk using temperature, wind speed, exposure time, and wet or dry conditions. This free aviation safety tool is intended for awareness and planning only.
Enter temperature, wind speed, exposure time, and clothing condition to estimate relative hypothermia risk.
Use this tool for conservative safety awareness, not for diagnosis or emergency decision making.
A hypothermia risk estimator is a cold exposure planning tool that looks at environmental factors such as temperature, wind, time exposed, and whether clothing is dry or wet.
In aviation and outdoor survival contexts, this kind of estimator can help reinforce how quickly cold stress can become serious, especially when wind and moisture are involved.
Wind often increases heat loss, especially in cold air, and can significantly worsen exposure risk when combined with long exposure time.
Moisture increases heat transfer and can accelerate body cooling, especially when combined with wind and low temperature.
No. This calculator only estimates exposure risk and is not a medical tool.
Seek urgent medical or emergency help, move the person to shelter if possible, remove wet clothing if safe to do so, insulate them, and follow current emergency guidance.
