66% of the work is heating. Months averaging under 55° run from November through March.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Bixby, OK.
Living with Coweta’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
212 frost-free days in zone 7b. The last frost comes by Apr 1 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 1.
Months with highs of 62–84° and lows of 40° or more: March, April, May and October. 4.5 miles of trails are waiting.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Coweta, OK | 28° | 93° | 44" | 2.7" |
| Lancaster, SC | 31° | 91° | 43" | 2.6" |
| Monroe, NC | 31° | 91° | 43" | 2.1" |
| Bonham, TX | 33° | 94° | 44" | 1.1" |
| Colonial Heights, VA | 29° | 90° | 47" | 3.5" |
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.
About as warm as it used to be
The last 30 years in Coweta averaged 0.3° warmer than the 1900s. The biggest change is in March (+1.6°).
A smaller shift than in all but 40 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 Coweta compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Coweta’s place among Oklahoma’s.
