Climates most like Hi-Nella’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 |
|---|---|---|---|---|
| Hi-Nella, NJ | 26° | 87° | 47" | 22" |
| Cave Spring, VA | 27° | 87° | 45" | 18" |
| Fort Thomas, KY | 24° | 87° | 45" | 23" |
| Charleston, WV | 25° | 87° | 46" | 32" |
| Forestville, OH | 23° | 86° | 45" | 23" |
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 Hi-Nella averaged 1.9° warmer than the 1900s. The biggest change is in December (+3.4°).
A bigger shift than in 87% 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 Hi-Nella compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Hi-Nella’s place among New Jersey’s.
