Weather and electricity in Mabank
Typical weather near Mabank, from the nearest NOAA station with a complete 1991-2020 record: Athens, about 22 miles from the city center (station elevation 448 ft). These are normals for that station, not readings at your address. August is the warmest month on average, with a normal daily high of 95°F; January has the coolest average low, 35°F. Average daily highs reach 90°F or more in June to August. No month averages a daily low at or below freezing.
For electricity, the normals point to two seasons that can lift a household's usage: cooling-degree days (a measure of how far each day's mean temperature sits above 65°F) peak in August at 580 for the month, and heating-degree days (below 65°F) peak in January at 586. How much that matters to a bill depends on the home, its insulation, its heating fuel and the household, so use your own usage history, not a regional average, when you compare plans.
| Month | Avg high °F | Avg low °F | Precipitation (in) | Cooling degree-days | Heating degree-days |
|---|---|---|---|---|---|
| Jan | 58 | 35 | 3.5 | 4 | 586 |
