Editorial policy
PlainClimate publishes figures NOAA has measured and the plain sentences those figures support; nothing else is presented as fact.

What gets published
A place gets a page when a NOAA station with 1991-2020 normals stands for it. A month gets its own page when the place is large enough, or searched for often enough, for the month to be asked about, and when the station has daily normals to describe it. A statement goes on a page only if a figure in the database supports it; when a figure is missing, the sentence is left out rather than estimated.
Pages and sections
Every page PlainClimate publishes is open to every search engine; none is hidden from one engine for being thin. A record that cannot answer its own question well is shown as a section of a fuller page instead: a second weather station in a town appears on the town's page with its own figures, and a town without a station is listed, with its population and distance, on the page of the nearest station with a full record. When new data lets such a record stand on its own, it gets its page in the next release.
Measurements, not verdicts
PlainClimate does not grade or score places. Lists such as "the cities with the most clear-sky hours" or the retirement guide's conditions state the measure they use, the NOAA field behind it and the population floor, so a reader can see why a place is on the list.
How AI is used
PlainClimate is built with AI tools, which write the code, the templates and the explanatory text of the guides and analyses. They do not decide the numbers: every figure is read from the database, and every analysis states its method and limits. Before publication the data editor role (AI agents running the checks listed on the methodology page) compares model-written text on guides and analyses with the database or the cited source; the last check ran on October 8, 2026.
Independence and advertising
The site is meant to be paid for by advertising: its pages carry Google AdSense's code, and ads appear once Google approves the site. No place, business or agency pays to appear, and no advertiser sees a page before it is published.
Corrections
Errors are corrected at their source in the pipeline, so the fix reaches every page that shows the figure, and listed on the corrections page with the date.
