-38°F is an extremely low temperature, equivalent to about -39°C. At this temperature, water freezes solid, and most outdoor activities become hazardous. It is well below the average winter temperatures in many regions, making it a rare occurrence in most places. At -38°F, exposed skin can freeze in just minutes, leading to frostbite. This temperature is often associated with severe winter weather conditions, such as blizzards or arctic air masses. People living in areas that experience such cold, like parts of Alaska or Canada, must take special precautions to stay warm and safe.
