The Perfect Weather Day: When Do They Occur Most?

My definition of a perfect weather day is a day with temperatures between 65 and 80 degrees with no rainfall. After analyzing ALL the days (more than 14,000) from 1980 to 2020 and plotting the instances for each day of the year, this is what I found:


Notice the typical increase in late spring, the drop in summer then the big increase in September and early October.  Once the pattern flips in mid October it rarely recovers (blue arrow).  Enjoy these days while you can :)
