WebThe heat index (see chart below) is the "feels like", or apparent, temperature. Dew point is the temperature of the air when it cools to a point where it saturates with water vapor (known as the dew point temperature). That means on a windy day in the winter, the wind chill will be notably lower than the actual air temperature. Wall or Table or Shelf mount. Just like how higher relative humidity levels make it feel warmer, the reverse is also true; low humidity levels make the air feel colder than it actually is.
