TownRatings’ own comparison of NOAA 1991–2020 normals, not a NOAA product: places of 5,000+ at least 150 miles away, one per state, closest on January low, July high, precipitation and snow.
| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Frisco, TX | 35° | 94° | 41" | 2.6" |
| Clearlake, CA | 35° | 93° | 40" | 0.4" |
| Cayce, SC | 35° | 93° | 46" | 1.2" |
| Evans, GA | 35° | 92° | 45" | 0.8" |
| Laurinburg, NC | 33° | 91° | 45" | 1.1" |
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Frisco averaged 0.8° warmer than the 1900s. The biggest change is in March (+1.8°).
A smaller shift than in 89% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods. In a city of 237,000 people, part of the change is the city itself: pavement and buildings hold heat (the urban heat island).
