Weather Factor's Perceived Temperatures combine Heat Index readings above 80 with Wind Chill readings below this level. The result is often a more accurate insight into the consumer's perception of how hot or cold it feels . Since this data is collected on a daily basis, by city, the same seasonal and geographic aggregations are available that have been discussed above. This variable measures the average daily wind speed at the weather station. Our primary use for this data is in computing Wind Chill readings, which allow us to better assess how consumer's are actually perceiving temperatures below 80 .
Normal data is available for average monthly wind speeds.
