July 1936 Heat Wave

A record heat wave baked the Midwest in early July 1936.  The temperature reached 100°F and above for a record eleven consecutive days from July 5 to July 11.  People had to cope with the extreme heat without the benefit of air-conditioning.  The all-time high and high minimum temperatures for the quad cities were recorded on July 14th when the mercury reached a sizzling 111°F and only dropped to a low of 84°F.  It was the warmest summer on record with an average temperature of 78.8 degrees.  July was also the warmest month with an average temperature of 85 degrees.
