Was Monday really the hottest September day ever in Boulder?

September 6, 2019 / BoulderCAST Team

Labor Day 2019 was Denver’s first 100-degree day ever to occur in September. It was also the latest 100-degree day observed, remarkably by more than two full weeks. The previous record high for September 2nd was 95 degrees. On Monday, this temperature was eclipsed before the lunch hour, with the prior record eventually being obliterated by 5 degrees later in the afternoon. The city of Boulder officially hit the century mark on Monday, too. The extreme heat had impressive historical significance here as well, with one small asterisk. Unlike Denver, Boulder actually only tied all of the existing records, as 100 degrees had already been observed on the very same day back in 1983. We investigate the validity of the triple digit observation this week and the one more than three decades ago.
