Dear Bob,
On average, Chicago’s temperatures rise faster in April than in any other month in the year. That is based on average temperatures in the 30-year period 1981-2010, and it is true for temperature statistics at both Midway Airport and O’Hare International Airport.
At Midway Airport the average April temperature is 50.4 degrees and for March it is 38.8, giving a temperature increase of 11.6 degrees; at O’Hare, the comparable numbers are 48.9 degrees and 37.9, for an increase of 11.0 degrees. The city’s average temperatures begin rising by the last week in January and continue upward until the middle of July, then turn downward again until the end of January.
