From 1899 to 2023, the average date of the first 100° day in the DFW metroplex was July 1.
The earliest occurrence of triple digits was over a century ago, on March 9, 1911. Forty years after that, we had the latest occurrence, when the thermometer hit 100° on October 3, 1951.
While it can seem that everyone locally has a “_____ summer was the worst” story, empirically one year stood above the rest. 2011 saw 71 days at or over100°.
Last summer was a hot one. DFW saw 50+ days at or over 100°, including 21 consecutive days. We had a relatively late occurrence of our final 100° day in 2023: September 24.
The bad news: The National Oceanic and Atmospheric Administration says there is a one in three chance summer 2024 is hotter than summer 2023.
We hit 100° for the first time on June 25. If that holds, you have 49 days remaining in the double digits. Get out and enjoy them.
