What to Expect on Your July Bill
June 2026 was a tale of two seasons, it felt.
The first half included several significant rainfalls, including a 3.55-inch deluge on June 7. The rain kept temperatures milder than usual with temperatures in the low 70s and even a low of 69 recorded on June 3. In all, North Texas received 8 inches of rain, nearly twice the norm.
Then for the last half of the month, the rain subsided and full-blown summer was here with a high of 98 degrees recorded on June 29.
CoServ Members should expect electricity usage to be higher than May, based on the Cooling Degree Days. Looking back at June 2025, Members should also expect electricity usage to be more than last year.
| May | June | Difference | |
|---|---|---|---|
| Average temperature | 74.8 | 84 | 9.2 degrees warmer |
| Heating Degree Days | 12 | 0 | 12 less HDD |
| Cooling Degree Days | 324 | 578 | 254 more CDD |
| Utilities and the federal government measure the impact of weather on energy usage by calculating Cooling Degree Days (CDD) and Heating Degree Days (HDD). To calculate the CDD, take the average temperature for a day and subtract it from 65. The higher the number, the more air conditioning will be needed to keep your home comfortable. Click here for more information on calculating CDD. | |||
The average temperature for June 2026 was 84 degrees, 9.2 degrees warmer than May. Temperatures reached 90 degrees or higher on 24 days last month and there were seven nights where the low temperature stayed at 75 degrees or above.
While this June was hot, it wasn’t nearly as bad as 2022 when temperatures topped out at 103 degrees and the Cooling Degree days totaled 640. Members may remember having higher than usual electricity usage, not just that month but throughout the summer of 2022.
