The plots below are the average dew point for each day from June 1 to September 30 since 1972 for Cleveland. I color coded each dew point range for easy reference.
Dark Blue: 30-49°
Light Blue: 50-59°
Light Green: 60-69°
Dark Green: 70-80°
First image is the month of June. Reading left to right for day one through 30. Horizontal black line separates each decade. I notice more breaks from high humidity days in the 1970s and 1980s. More consistently high humidity in the mid/late 1990s into the early 2000s. Recently, lower humidity days seem more frequent in the first half of the month
Second image is July. Over the last 10-15 years the frequency of "lower humidity" days (light blue) seems less than previous decades.
Third image is August
Fourth image is September:
Let's only display the days with dewpoints UNDER 60. Basically more comfortable days. Now we can see the frequency of delightful days for each summer month/day. Some quick observations:
* Breaks in the humid days in June look to be more frequent in the 1970s/80s and early 2000s
* Breaks in humid days in July more frequent in the 1970s, early 80s and early 2000s.
* Breaks in humid days in August more frequent in the 1970s.
* Breaks in humid days in early September more frequent in 1970s and 1980s
