This morning’s low of 60 is our 9th low of 60+ this month, making this the 9th consecutive September with at least 9 lows of 60+. Prior to this stretch, we’d never done that more than 5 years in a row at the airport, and never at any observing site in the period of record outside of an extremely suspect stretch from 1889-1913 where every September had double digit days with lows of 60+.
