This post is an overview of the March weather in Chicago, including snow and precipitation forecasts, as well as tips on how to dress and things to do.
March begins cold in Chicago when early morning low temperatures will likely be in the mid-20s F (-4C to -3C) with a few of the colder mornings dropping down to near 15 F (-9C) or less.
Daytime highs early in the month will tend to be chilly, mostly near 40 F (4-5C).
As the month progresses, however, the days quickly warm up and by the end of the month the morning lows are more likely to be in the mid-30s F (1-2C) with afternoon highs in the low to mid-50s F (11-12C).
A few of the warming afternoons can occasionally reach into the upper 60s F (20C) or more.
Over the years Chicago has seen March temperatures as low as -8 F (-22.2C) to as high as 88 F (31.1C)!
Skies tend to be sunny or at least partly sunny on about 13 days this month so there are ample days to explore this city.
Some precipitation is likely on about 11 days, however, only 1 or 2 days will see significant precipitation of 1/2 inch (13mm) or more.
Of the 11 days with precipitation, about 4 will likely have some snow.
Winter ware is still a must here early this month so dress in layers with a medium or heavy jacket and also a warm hat and gloves.
As the month progress, the weather eases a bit so you may only need a light to medium weight jacket or even just a sweater for those warmer days.
