How to read these numbers
- Statewide averages blend mountains, coasts and deserts; local climate can differ a lot.
- D.C. is not part of NOAA's statewide series. Alaska and Hawaii are included but not in the contiguous-U.S. average.
- Annual averages hide seasonal extremes: a state with mild winters can also have very hot summers.
