English: The red shading on this map denotes areas of the United States with a solidly humid subtropical climate; the pink shading denotes areas of the United States with a transitional/borderline humid subtropical climate.

I created this map based largely on the information contained in the Humid subtropical climate article, with supplemental information gleaned from articles about various US cities and states. Consider this to be a work in progress and feel free to suggest changes/corrections to me or make them yourself, if necessary.

Points of clarification:

• The Florida Keys are intentionally left uncolored because these areas exhibit a true tropical climate.

• Southern Florida (e.g. Miami area) is shaded pink to indicate transition to a true tropical climate.

Also, the transitional zone in the west may need to be extended north to cover all of eastern Oklahoma and terminate in extreme southern and eastern Kansas (per the Kansas article's description of the climate of Kansas).
