The city proper tied the old record of three consecutive 100-degree days which was set back in August 1947. Normally, the highest temperature recorded in a typical Chicago summer is around 95 °F (35 °C), a streak of 3 days above 90 °F (32 °C) constitutes a "heat wave", and the thermometer reaches or surpasses 100 °F (38 °C) only once every five to ten years.
