Which month in Chicago hosts the most triple-digit record highs?
Thanks, Robert J. Lifka Brookfield
July is the city’s “poster-child” month for hot weather with record highs in the 100s on 21 of the 31 days, including an impressive 10-day run during the city’s hottest time of the year from July 13-22. June and August claim runner-up honors with eight triple-digit record highs and September trails with just three. Chicago’s earliest- in- the-season 100-degree plus record high was 102-degrees on June 1,1934 and the latest was a high of 100 on September 7, 1960. The vast majority of the city’s triple-digit record highs occurred during the torrid summers in the 1930s and 1950s. The most recent were during the deadly July, 1995 heat wave with record highs of 104 on July 13 and 100 on July 14.
