Preliminary Climate Summary for July 2021: July of 2021 will be remembered by Minnesotans for worsening drought, Heat Advisories, and frequent poor air quality due to smoke from Canadian wildfires. Warm and dry are the two most appropriate climate words for July. Most climate stations reported a mean monthly temperature that was from 1°F to 4°F above normal. Combined with the near-record warm June, the June-July two month period in 2021 is the 3rd warmest in history on a statewide basis (only 1933 and 1988 were warmer). Extreme temperatures for July were 102°F at Granite Falls (Yellow Medicine County) on July 4th and just 32°F at Seagull Lake (Cook County) on July 8th. Many areas saw 10 to 12 days with afternoon high temperatures of 90°F or greater. MSP Airport reported 10 such days, adding to the 12 recorded during June. The 22 days with 90°F or above at MSP for the months of June and July in 2021 rank 3rd historically (tied with 1894 and 2012). There were 30 such days in 1988...
