Weather and electricity in Prosper
Typical weather near Prosper, from the nearest NOAA station with a complete 1991-2020 record: Mckinney Municipal Airport, about 14 miles from the city center (station elevation 580 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 96°F; January has the coolest average low, 34°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 601 for the month, and heating-degree days (below 65°F) peak in January at 631. 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 | 34 | 2.7 | 2 | 631 |
