MONDAY, AUGUST 7 - HASN'T BEEN ANY HOTTER THAN THIS


I always keep a few books on the desk here in the weather center. One is this dusty old black-covered volume of daily weather observations from 1918. I always keep the book open to August 7. When I point out some of the numbers on that page, I usually get a few oohs and aahs from our visitors.

You see, August 7, 1918, was the hottest day ever officially recorded in this area, and these are the hourly observations from that day in Philadelphia. The temperature that morning bottomed out at only 84 degrees. And under blazing sunshine, the temperature reached 100 by 11am, and stayed above 100 until 6pm that evening. In between, at exactly 345 in the afternoon, the temperature peaked at 106, establishing a record for heat that still stands today.

Wilmington also set its all-time record high temperature that day, one-upping Philadelphia by reaching 107.
