Just for fun, I decided to take the information about dew points given on Wikipedia and add my own "comfort index" lines, to show which combinations of temperature and dew point create different kinds of comfort or discomfort zones. Because... sometimes it's cool and clammy, and other times it's hot and steamy.
No one ever shows what I've shown below. So I invented my own chart!
It may not be as scientifically accurate as it should be,
but I use it to estimate or approximate the expected comfort level each day.

Let me know if you don't agree with the subjective language labels and where they are placed.
