Weather and electricity in Highland Park
Typical weather near Highland Park, from the nearest NOAA station with a complete 1991-2020 record: Dallas Love Field, about 4 miles from the city center (station elevation 440 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 97°F; January has the coolest average low, 38°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 July at 691 for the month, and heating-degree days (below 65°F) peak in January at 537. 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 Dallas County
The Texas Railroad Commission's county table lists a record low of -10°F (1899) and a record high of 115°F (1909), and a regional estimate of 30 consecutive hours as a typical longest freezing or frozen-precipitation period for Dallas County. These are historical county extremes, not Highland Park'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 Highland Park, and not an estimate for your home. EIA source.

No Highland Park ZIP code carries a split flag, but only an address lookup is certain.

75205. It holds 2,710 Highland Park-addressed competitive homes; counting every address in the ZIP, ERCOT has 11,062 meters for roughly 9,655 households, a 1.15 ratio.
Are electric bills high in Highland Park?
Depends on the part of town. The ACS 2020-2024 found 39.0 percent of 75205 households paying over $250 a month for electricity and 11.1 percent in 75219. Home size, age and electric heating drive most of that gap, so compare plans at your own usage.

75205 covers part of Highland Park, but the Postal Service names most of it Dallas: that postal city is on 40 percent of the ZIP's 11,062 competitive home meters, Highland Park on 24 percent. Your mailing city is not your city limits; the service address decides the utility.
