Weather and electricity in Santa Fe
Typical weather near Santa Fe, from the nearest NOAA station with a complete 1991-2020 record: Houston Nwso, about 6 miles from the city center (station elevation 19 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 92°F; January has the coolest average low, 46°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 592 for the month, and heating-degree days (below 65°F) peak in January at 337. 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.
| Month | Avg high °F | Avg low °F | Precipitation (in) | Cooling degree-days | Heating degree-days |
|---|---|---|---|---|---|
| Jan | 64 | 46 | 4.8 | 20 | 337 |

Historical weather records for Galveston County
The Texas Railroad Commission's county table lists a record low of 7°F (1899) and a record high of 106°F (2000), and a regional estimate of 18 consecutive hours as a typical longest freezing or frozen-precipitation period for Galveston County. These are historical county extremes, not Santa Fe'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 Santa Fe, and not an estimate for your home. EIA source.

Common questions about electricity in Santa Fe
Can I choose my electricity provider in Santa Fe?
Yes, where CenterPoint's wires reach the house, which in Santa Fe is most of the city: 9,111 homes with a Santa Fe mailing address were on the competitive market on October 5, 2026, 1.94 for each Census household. Addresses in 77510, 77511 (all split) need an exact-address check before you shop.
Which Santa Fe ZIP code has the most homes on the competitive market?
That is 77510, home to 6,412 of the competitive meters with a Santa Fe address. ZIP-wide: 6,643 ERCOT meters, about 5,441 Census households, 1.22 per household.
How many Santa Fe households have a $250 electric bill?
Depends on the part of town. The ACS 2020-2024 found 52.9 percent of 77517 households paying over $250 a month for electricity and 52.4 percent in 77510. Home size, age and electric heating drive most of that gap, so compare plans at your own usage.
How do I start electric service at a new Santa Fe address?
Start with the address check: CenterPoint-delivered Santa Fe homes choose among the plans offered there and set a start date. Turnover is real in 77510, where 10.8% moved in the past year (ACS); ERCOT logged 7 vacant-to-active meters in 77510 Oct. 7-18, 2026.
Why are there more electric meters than households in Santa Fe?
9,111 Santa Fe-addressed meters against 4,693 city households is 1.94 per household: the Santa Fe postal area extends past city limits, and new homes get meters before the Census counts them. It doesn't mean every nearby address can choose.
Who do I call in Santa Fe when the power goes out?
Call CenterPoint (centerpointenergy.com/outage), the wires utility for Santa Fe's 9,111 competitive homes; a retail provider can't fix lines.
