How we got this. We add up NOAA's twelve monthly precipitation normals, 1991 to 2020, at each city's nearest airport station that reports them. A state is the population-weighted mean of its five largest cities, not NOAA's statewide figure, so it reads where most people live. Cities and states rank on their own lists. It refreshes when NOAA reissues its climate normals.
Rankings by The Honest Local from public data, one page per list, refreshed on each source’s own cycle. Places with no reading are left out rather than estimated. Every value on this page carries its source in the page’s structured data.
