Weather and electricity in Colorado City
Typical weather near Colorado City, from the nearest NOAA station with a complete 1991-2020 record: Colorado City, less than a mile from the city center (station elevation 2,110 ft). These are normals for that station, not readings at your address. July is the warmest month on average, with a normal daily high of 97°F; January has the coolest average low, 28°F. Average daily highs reach 90°F or more in June to August. Average lows are at or below freezing in January to February and December.
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 580 for the month, and heating-degree days (below 65°F) peak in January at 680. 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.
