Top Ten Monthly Extremes for Madison, Wisconsin

Warmest,  Coldest, Wettest,  Driest,  Snowiest,  Least Snowiest
* Prior to 1896, temperatures were recorded 3 times daily, at 7am, 2pm, and 7pm, so absolute maximum and absolute minimum values are absent from climatological calculations. During winter, this would likely skew monthly averages to be milder than actual. *
