While autumn officially doesn’t start until Sept. 23, the meteorological summer just ended on Aug. 31 and, as Luminant’s Chief Meteorologist explains, it was warmer than normal in North Texas.
From June through August, the average temperature at DFW Airport was 85.6 degrees, Michael Whitehead says. “This average temperature was 1.5F degrees above normal, which made summer 2015 the 18th warmest on record.”
Although the humidity made the heat index feel like 103 to 105 for much of July, DFW didn’t top 100 degrees until July 26.
“A bit of good news is that the record rains of May (16.96 inches at DFW) ended the state’s severe drought and contributed to a summer with fewer than normal 100-degree days,” Whitehead says. “DFW recorded 13 days with triple-digit highs vs. the normal 18 days.”
A streak of 41 consecutive days without rain, from July 9 to Aug. 18, ranks the third longest dry period on record and coincided with the hottest month-long period of the year and record-breaking electricity demand across the state.
