A four-month summer in Minnesota?

By one metric, summery weather has lasted almost four months in the Twin Cities this year.

The daily high temperature in the Twin Cities has reached at least 70 degrees every day since May 26. With Tuesday’s highs expected in the 80s, that will make 118 straight days of temperatures of 70 degrees or warmer.

The previous record was 108 days, set in 2018. So it appears we’ll break that record by a full 10 days this year. Kudos to MPR News meteorologist Sven Sundgaard for mentioning this on Morning Edition Monday.

Long summer, but not the warmest on record

This summer was warm for Minnesota, and September temperatures are off and running. Temperatures so far this month are running 2 to 6 degrees warmer than average across most of Minnesota.

The Twin Cities is running 4.3 degrees warmer than average through Sept. 18.

Last year was the hottest summer on record for the Twin Cities and most of Minnesota. The average temperature in the Twin Cities last summer was a toasty 75.7 degrees. That beat out 1988, 1933, and 2012 for the top spot.

The summer of 2022 started warm with temperatures 3.3 degrees warmer than average in June in the Twin Cities. But temperatures came in 2.2 degrees warmer than average in July and just 0.7 degrees warmer than average in August. So this summer didn’t even crack the top 15 hottest summers in 149 years of records in the Twin Cities.

Overall temperatures in the Twin Cities are running about 3 degrees warmer than average since June 1 this year. That’s more typical for Des Moines, Iowa, than the Twin Cities.

So I hope you have enjoyed our Des Moines-like summer of 2022.
