During the summer of 1936, Seymour, Indiana had 49 days over 100 degrees and reached 113 F (45C)
Most of the 100 degree days came during two heatwaves. A 15 day stretch in July and a 20 day stretch in August.
Indiana very rarely has 100 degree days any more. Fraudsters like Katharine Hayhoe claim that summers are getting hotter, but they are lying.
