The best year of the quintessential Cfa climate and my favorite Southeast US place to monitor, compared to the same year in its coastal and same latitude counterpart. I would have used the downtown waterfront station for Charleston but there is no Dallas station with 2017 data that is urbanized enough to be apples to apples with it, so I stuck to the airports.
Both are about equally poor weather wise to live in for me, so I'll compare them on the basis of their weather monitoring, and Dallas Love Field is the pick for me.
More wintertime heat and a much longer frost free season, unlike the dumb March 16-17 backload Charleston Airport got after a frostless February. Plus it has a fun 2017 rainfall pattern to watch that seesaws between Cwa, Csa, and the standard of dry winters and summers with wet springs and falls.
