Disclaimer
This disclaimer explains what the numbers on AverageClimate.com are — and, just as importantly, what they are not. It was last updated in October 2026 and applies to every page on the site.
Averages are not weather
Every figure on this site is a climate normal: an average over the 30-year period 1991–2020, computed by NOAA's National Centers for Environmental Information from weather-station records. An average high of 84°F for July means that, across thirty Julys, that was the typical afternoon temperature at that station. It does not describe any particular July, week, or day — individual days in that month can be, and routinely are, far hotter, colder, wetter, or drier than the normal. If you are planning around a specific date, use the normals to set expectations and a National Weather Service forecast for the actual decision.
One station stands in for a city
Each city profile is built from a single representative station — usually the city's main airport or National Weather Service station — named, with its official NCEI identifier, on the page. Climate varies within cities: elevation, distance from water, and urban development can shift temperatures and precipitation by meaningful amounts across a few miles. Treat a city's profile as the climate of its station and a good approximation of the metro area, not a measurement of every neighborhood.
Rankings and "best month" picks are editorial tools
Our city rankings and best-month recommendations are computed transparently from the normals — the method is described on the About page — but any single-number ranking simplifies a climate that different people experience differently. A month we rank poorly for heat may be exactly what a heat-lover wants. Use the tables, not just the rankings, when the decision matters to you.
No professional advice
Nothing on this site is engineering, agricultural, medical, financial, or safety advice. Decisions with real consequences — building design, crop selection, flood risk, event safety — require current data, local expertise, and official sources. We accept no liability for losses arising from reliance on the averages published here.
Using normals responsibly
Normals reward being read as ranges rather than promises. When a city page says July averages a high of 91°F, the honest reading is that a typical July day reaches about that temperature — some years the same month averages several degrees hotter, and a single heat wave can push a week far above the normal while the month still finishes near it. Precipitation is even more variable: a city's "wettest month" can deliver twice its normal rain or almost none, and annual totals commonly land 20–30% above or below the normal in a given year. Snowfall varies most of all, especially in cities where one storm can supply a season's worth. Plan with the normals, but leave margin for the variance they conceal.
