Turbulence may be caused at any time without warning. However, with proper knowledge and avoidance you can reduce the chances of having an incident due to turbulence. East wind days at Skydive Chicago tend to be the most turbulent. Wind coming off the bluff, trees, and hangar can cause undesirable landing conditions.  However Skydive Chicago has a large landing area in which there are other locations to land that will not be affected as much. The map located to the right is just a guideline.  The effects of turbulence may be prevalent outside the area presented on this  map.  Please use caution and make safe choices on where to land.
