I didn't include CLE because of apparent sensor issues over the past couple of years. CLE has been running about 1-1.5F cooler, relative to average, than the other first-order climate sites in CLE's forecast office. Based on climatological normals, CLE should be the second warmest site in the summer (TOL being first warmest) and the warmest in the winter. Yet, inexplicably, it's been reporting the second coldest temperatures in the WFO (only YNG cooler). So it would appear that the temperature sensor is currently reading too low.

A sensor error of a degree or so can make a huge difference in the summer rankings since there's not that much variance in the temperature records compared to other seasons. Another degree would have put it closer in line to surrounding sites (TOL, MFD, CAK and ERI), all of which recorded top three hottest summers. I would surmise that, if it didn't feel too hot, it was likely due to how many recent years are on this list (2016, 2010, 2005, 2018, 2012, 2017, 2021, 2011, 2002, 2019).

Spartman Special in Dayton this summer. Tied 2007 for 10th warmest August, plus 10 90+ days during the month. 14th warmest summer on record and, more importantly, the warmest since 1995 and third warmest on record at the airport (surpassed only by 1995 and 1988). Most of those early years should be tossed from the downtown rooftop station. August Summer

Similar story in Mansfield. Third warmest August, and the #1 warmest summer on record (edging out the scorching summer of 2020, and the Dust Bowl era summer of 1934). August Summer

Third warmest August, and third warmest summer on record at Akron/Canton. The all-time warmest summers occurred "way back" in 2016 and 2020, narrowly edging out this past summer. Also the top 4 warmest summers there have occurred in the past six years (2016, 2018, 2020, and 2021). August Summer

Yet another scorcher of a summer. Third warmest August, second warmest summer on record at Toledo (surpassing last year's mark): August 2021 Summer 2021
