September 22, 2017 is the astronomical start of fall here in the Northern Hemisphere! The interactive map below (click on image to link to website) has been produced to forecast peak leaf colors each year. The map compiles National Weather Service data on historical temperatures, forecast temperatures, and forecast precipitation, as well as historical leaf peak and peak observation trends in order to make the most accurate predictions.
Travel Wisconsin also maintains an interactive Fall Color Report, which shows what colors are presently like across the state and when they're expected to peak.
The Wisconsin DNR provides plenty of information on the changing colors in Wisconsin, including all the nerdy science things you may (or may not) care to learn about leaf colors (if you did not already know).
We are hoping you get to enjoy the beautiful colors and outdoor activities before it is too cold out!
