Coastal/island climates vs. continental climates

I’ve split my January/July average high temperature data into two subsets: 1) Islands, West Coast states, and Florida; and, 2) Everything else (continental United States).

The subsets obviously constitute two completely different climate patterns:

(The outlier on the continental U.S. plot is the top of Mt. Washington in New Hampshire. There’s little reason to expect a 6,288-foot mountaintop to fit the continental pattern.)
