We also feel uncomfortable when dealing with low dew points, but usually a lower
dewpoint is considered more comfortable because of the accompanying lower
temperatures.
MIN AND MAX DEWPOINT
The minimum and maximum dew points are recorded and displayed in the Dewpoint section of the Heavy
Weather Pro application. To view or reset the min and max dewpoint values,
see the section on Min Max Values .
WINDCHILL
WHAT IS WIND CHILL?
Wind Chill is what the temperature “feels like” due to the wind. How much it effects us depends on both air
temperature and wind speed. The wind chill temperature is more commonly called the wind chill factor.
Note: Wind Chill measurement methods vary over time, as established by the National Weather Service and other
weather reporting authorities. This weather station uses the classical wind chill values.
HOW DOES WIND CHILL AFFECT ME?
Our bodies lose heat mainly through evaporative cooling and convection. The rate of heat loss by a surface
depends on the wind speed above that surface: the faster the wind speed, the better the surface cools.
For inanimate objects, the effect of wind chill is to reduce any warmer objects to the
ambient temperature more quickly.
For people, the body’s response is to try to maintain surface (skin) temperature. This
attempt to maintain the skin temp makes us feel colder. In certain conditions, wind
combined with cold temperatures can actually cause the skin’s temperature to
decrease, and can even cause frostbite.
Note: Monitoring Wind Chill is an important safety factor in colder seasons.
