- : Version 3: each place matched to the station that keeps its official record, and towns without a station listed on the nearest station's page; month pages for large places; state month, frost-date and station pages; frost probabilities, growing season, degree days, the plant hardiness zone, humidity, wind and sky; station records and recent years; six original analyses; a new design; every page open to every search engine. The same day, after review: NASA sunshine, NOAA's gridded normals for places of 50,000+ without a station, the USDA 2023 zone of every ZIP area, official state records, metric units and a true date of last change on every page.
- : Data correction: state and national precipitation averages use their own count (see the corrections page).
- : Daily normals and station warming trends added; place identity checked against the 2024 Census Gazetteer.
- : Data correction: rankings rank places, not weather stations (see the corrections page).
- : The climate location finder, downloadable climate cards and per-page data downloads added.
- : Data corrections: generated series and unsupported sunshine claims removed; the growing season computed for every place (see the corrections page).
