ASK TOM WHY: How many temperature records did we break during the summer heat of 1988?

Dear Tom,

 
How many temperature records did we break during the summer heat of 1988?

 

Ann Risum, Homer Glen, Ill.

 

Dear Ann,

 

Chicago established 16 heat records during the drought summer of 1988, more than in any other summer in official temperature records dating from 1871. We define summer as the 92-day period from June 1 through August 31.

 

Afternoon temperatures sizzled at 100 degrees or higher on seven sweltering days, the most ever in a summer, and rose to 90 degrees or higher on 44 days, also the most ever. The average high temperature that summer was 87.3 degrees, highest ever, and slightly ahead of the runner-up summer, 2012, with 87.0 degrees.

 

In addition, the city set or tied 13 daily heat records in that 1988 summer: nine daily high temperature records and four daily highest minimum records.
