Saturday September 2 2017  showed Baltimore something special. The high temperature at BWI airport was only 63ºF. This set the record for the coolest afternoon high temperature for that date. Ironically it was in part to a former hurricane that helped do this and not the first time. This chill has given reason for many to complain that it feels as if summer ended too early, especially on this Labor Day holiday weekend. It has been quite a contrast to the record heat out west, flooding rains from Harvey, and anxiety of Hurricane Irma in the Atlantic.

Here are the stats for the day that you may be able to use at your Labor Day BBQ.

  • The high of 63ºF was at 5 AM and then dropped, only to recover at 10 PM. Most of the day was actually cooler than this.
  • This was 20 degrees cooler than normal.
  • September 2nd average High Temp = 83ºF
  • October 27 to 30 has an average High Temp = 63ºF
  • This broke the 82 year old record for the date of 64ºF set back in 1935
  • This was similar to the record cool summer day: High temperature of 60ºF on June 23 in 1972 following Hurricane Agnes.
