Weather and electricity in Port Aransas
Typical weather near Port Aransas, from the nearest NOAA station with a complete 1991-2020 record: Port Aransas, about 2 miles from the city center (station elevation 12 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 89°F; January has the coolest average low, 50°F. No month averages a daily high of 90°F or more. 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 598 for the month, and heating-degree days (below 65°F) peak in January at 276. 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 Nueces County
The Texas Railroad Commission's county table lists a record low of 7°F (1899) and a record high of 113°F (1983), and a regional estimate of 18 consecutive hours as a typical longest freezing or frozen-precipitation period for Nueces County. These are historical county extremes, not Port Aransas'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 Port Aransas, and not an estimate for your home. EIA source.
