Weather and electricity in Sweeny
Typical weather near Sweeny, from the nearest NOAA station with a complete 1991-2020 record: Angleton Brazoria Airport, about 15 miles from the city center (station elevation 25 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 93°F; January has the coolest average low, 45°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 586 for the month, and heating-degree days (below 65°F) peak in January at 332. 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.

Historical weather records for Brazoria County
The Texas Railroad Commission's county table lists a record low of 5°F (1899) and a record high of 109°F (2000), and a regional estimate of 18 consecutive hours as a typical longest freezing or frozen-precipitation period for Brazoria County. These are historical county extremes, not Sweeny's monthly averages and not a forecast; the normals above describe ordinary months.
Reference only: the U.S. Energy Information Administration's 2020 Residential Energy Consumption Survey puts the average Texas household at about 13,440 kWh a year (about 1,120 kWh a month if spread evenly). That is a statewide average for 2020, not Sweeny, and not an estimate for your home. EIA source.
