Wind Roses and Wind Frequency Tables for Illinois

Dr. Jim Angel, State Climatologist

These data are compiled from the available sites that have long-term wind statistics. The averaging period is 1961 to 1990, rather than 1971-2000, due to limitations in the software.

Note: wind direction is reported as the direction from which the winds are blowing. For example, a "south wind" means the wind is blowing from the south to the north.
