Labor Day is considered the unofficial end of summer, but does summer really end near Labor Day? If one considers the warmest 91 day stretch of the year to be summer, then this saying is a close approximation. The featured chart shows the end date of the warmest 91 day period for the areal averaged temperature for Iowa. The end date this year is shown as August 26, so we have been out of summer for a number of days now! The average end date is near 7 September. A simple linear fit is shown to this chart, the trend is the period to end sooner each yet.
