Climates most like Jamestown’s, farther away
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 |
|---|---|---|---|---|
| Jamestown, NC | 30° | 89° | 46" | 7.1" |
| Manchester, VA | 28° | 89° | 47" | 8.8" |
| Salisbury, MD | 27° | 89° | 46" | 8.0" |
| Fayetteville, AR | 26° | 89° | 47" | 6.5" |
| Washington, DC | 27° | 89° | 44" | 5.8" |
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 Jamestown averaged 1.3° warmer than the 1900s. The biggest change is in December (+2.5°).
A smaller shift than in 54% 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.
How Jamestown compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Jamestown’s place among North Carolina’s.
