What a year in Langley feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 232 frost-free days a year

Heating and cooling a home in Langley
53% of the work is heating. Months averaging under 55° run from November through February.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Aiken 5se, SC.
Living with Langley’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
232 frost-free days in zone 8b. The last frost comes by Mar 21 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Nov 7.
Months with highs of 62–84° and lows of 40° or more: March, April, October and November.

Climates most like Langley’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 |
|---|---|---|---|---|
| Langley, SC | 35° | 93° | 47" | 0.7" |
| Lindale, TX | 36° | 93° | 46" | 0.7" |
| Cusseta, GA | 36° | 92° | 50" | 0.5" |
| Lumberton, NC | 34° | 91° | 48" | 1.2" |
| Texarkana, AR | 34° | 93° | 52" | 2.1" |
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 Langley averaged 0.9° warmer than the 1900s. The biggest change is in February (+1.6°).
A smaller shift than in 83% 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 Langley compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Langley’s place among South Carolina’s.
