Denver’s hit 90 degrees 12 of 17 days so far this month – The Denver Post

It’s not just you sweating through June along the Front Range. It’s been an exceptionally hot start to the month.

Denver hit 90 degrees again on Wednesday, marking the 12th time so far this month that Denver has hit that temperature.

The Mile High City averages only six 90-degree days each June, based on a long-term average of official data from the National Weather Service.

And last year, Denver didn’t officially hit 90 degrees for the first time until June 26.

Through Wednesday, Denver’s average month-to-date temperature so far this June is 71.4 degrees, tying it for the seventh-warmest start to the month of June on record.

While a pronounced respite from the heat moved in with a cold front on Wednesday, temperatures will likely rebound back into the 90-degree range by early next week. Next week also appears to lean on the warmer side of average. That could threaten Denver’s current record for 90 degree days in the month of June. The current record is 19 days, set back in 2006.

This month’s heat mostly owes to a persistent ridge of high pressure that’s been anchored over the upper Midwest, and it’s led to multiple waves of searing heat along the Front Range and throughout Colorado. It’s also kept Colorado on the drier side, with barely a half-inch of rain at Denver International Airport so far this month, as of Wednesday, which is less than half of the month-to-date average.

The drier and warmer pattern has sparked several wildfires in drought-stricken southwest Colorado, and if the pattern continues, it could lead to a summer filled with increased fire danger.
