Weather and electricity in Richardson
Typical weather near Richardson, from the nearest NOAA station with a complete 1991-2020 record: Richardson, about 3 miles from the city center (station elevation 678 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, 36°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 July at 614 for the month, and heating-degree days (below 65°F) peak in January at 595. 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.

|---|---|---|---|---|---|
| Jan | 56 | 36 | 2.8 | 2 | 595 |
