DC weather history for October 8

Tropical air in 2017 sent the overnight low to a record 75 degrees, creating unusually hot and humid October conditions more typical of midsummer.

On this day in 2017, the low temperature was just 75 degrees, the warmest ever observed in October. “It was also abnormally humid,” I wrote at the time. “The thick, tropical air surged north Saturday as Hurricane Nate made landfall along the northern Gulf Coast. By Saturday night, humidity levels were high even by midsummer standards.”

Dew points, a measure of humidity, were in the mid-70s. The high that day was an uncomfortable 83 degrees, more than 10 degrees above the norm.
