This page's numbers, as JSON:

curl "https://api.climatedata.dev/v1/us-climate/tavg/usa.json"What this can't tell you
- The contiguous US average leaves out Alaska and Hawaii, as NOAA's national series does; both are on the map as states.
- No NOAA series for 7 of the registry's states here (American Samoa, District of Columbia, Guam, Northern Mariana Islands, Puerto Rico, U.S. Minor Outlying Islands…).
- The most recent months are preliminary and NOAA revises them in the next release.
How the answer is decided
Each month is ranked against the same month in every year on record (since 1895 for most places). The top tenth of the record is 'much warmer than normal', the top third 'warmer', the middle third 'near normal'. States are coloured by the same five words.
