How Weather Impacts Utilities in San Antonio

In San Antonio, scorching summer temperatures are the biggest driver of high utility bills. As the mercury rises, air conditioners kick into overdrive to keep homes cool. It’s not uncommon for electric bills to double or even triple during the hottest months of June through September.

While winters are relatively mild, a sudden cold snap can trigger a spike in heating costs. Natural gas bills tend to be highest in December and January, when overnight lows can dip into the 30s.

Spring and fall offer a bit of a reprieve, with more moderate temperatures reducing the need for heating and cooling. However, seasonal rainfall can still bump up water bills, especially if you have automatic sprinklers.
