Weather and electricity in El Campo
Typical weather near El Campo, from the nearest NOAA station with a complete 1991-2020 record: El Campo, less than a mile from the city center (station elevation 110 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, 42°F. Average daily highs reach 90°F or more in June to September. 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 623 for the month, and heating-degree days (below 65°F) peak in January at 367. 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.
