Why Your Body Is Built to Survive the Hottest Places on Earth

September doesn’t mean 90° heat disappears everywhere. On average, Minneapolis and Chicago record their final 90° day around late August, while cities across the South and West can remain that hot well into October. Phoenix typically holds on the longest of the cities shown, with an average final 90° day around October 30. These are long-term averages. Any year’s final 90° day can arrive weeks earlier or later. #WeatherTok #SummerHeat #Climate #Meteorology #FallWeather
