Denver has not had a 100-degree day yet this year

Denver hasn’t had a 100-degree day this year yet, and odds are this might be the first time in eight years the city doesn’t have one.

With the unusually rainy start to summer this year, Denver’s temperatures stayed cool longer, so the city’s average temperatures in June and July, when the most 100-degree days happen, were only 75 degrees and 89 degrees, respectively.

So far in August, the average temperature has been 88 degrees. By this time last year, Denver already had five days of 100-degree temperatures.

“We’ve had at least a few 100-degree days over the last few years,” said Zach Hiris with the National Weather Service in Boulder. “2020 had quite a few, but we haven’t hit it yet this year, and to be quite honest, it’s difficult to say if we will.”

More hot weather is on the way in the coming few weeks, but how likely is it that Denver could see a 100-degree day now?

“(Monday) was probably our best chance of getting one,” Hiris said. “We’ve only had two 100-degree days occur after Aug. 21, so if we don’t see something in the next week or two I think we’re in the clear.”

That’s not to say it’s not been hot, Hiris acknowledged, saying that even though it hasn’t hit 100 degrees yet, temperatures have been right below 100 several times already. Monday hit a daily record with 99 degrees, and highs have been in the 90s for a week, with more on the way.

Denver was on a heat alert Monday and another one Tuesday for more temperatures over 95 degrees.
