Ask any old guy who was around in 1936.
Some stations in the American Midwest reported minimum temperatures at or above 90 °F (32 °C) such as 91 °F (33 °C) at Lincoln, Nebraska on July 25, 1936; the next and most recent time this is known to have happened is a handful of 90 °F (32 °C) minimums during a similar heat wave in late June 1988 but far less intense than that of 1936. The highest nightly low temperature outside of the desert south-west was 94 °F (34 °C) at Atchison, Kansas during the heat wave of July 1934.
The LOW in Lincoln was 91! The same month there was a high in NORTH DAKOTA of 121!
2016 was the highest in history, BS!
