We are coming off of a very hot summer. Following is some data that helps support that claim:
- 52 days at or above 100 degrees.
- We average 20 per year.
- In 2025, we only had 7.
- We hit a high of 109 degrees on August 24th.
- The high in 2025 was 104 and the high in 2024 was 107.
- We had very warm nights.
- We tied the record high minimum temperature of 86 degrees on August 24th.
- It was the hottest September on record.
- We had 15 days where it reached 100 degrees. The previous record was 8 days, and we only average 1 day.
- The average high temperature in September was 98 degrees, which is 2.5 degrees warmer than the previous record.
- It was the first September on record where the high every day was at least 90 degrees.
- The average temperature was 87.9 degrees, which is 9.4 degrees above normal.
With that being said, it has finally begun to cool down some. With these cooler temperatures, average pool water temperatures in the Denton area are definitely dropping—we are now seeing average water temperatures in the high 70’s to low 80’s.
According to the National Oceanographic Data Center, 70-78 degrees is where most people feel most comfortable swimming. I am not sure who “most people” are, but from what I have observed, 70-78 degrees is a bit cold for most of us north Texans. Most of us seem to prefer between 80-84 degrees, but it really depends on the individual and what type of swimming is being done.
For those who do not heat their pool, the swim season will be ending soon, if it hasn’t already. But for those who heat their pools this time of year, comfortable swimming will take place for a couple of more months. Pool heaters, in the north Texas area, can stretch the swim season from 5-6 months per year to 9-10 months per year. Due to this fact, now would be an excellent time to consider having a swimming pool heater installed. Having a heater on your pool can assure that you are able to swim from February/March thru November/December.
In the north Texas area, the predominant type of pool heaters use one of two fuels—natural gas or propane, depending on what is available at your residence. The basic principle of the pool heater is simple. A gas burner tray creates heat. The heat rises through the cabinet of the heater, raising the temperature of the water that is passing through the coils.
Vast improvements have been made to swimming pool heaters over the past several years, which allow them to be more efficient, cost-effective, and reliable. Another reason that contributes to an increase in pool heater sales is the fact that homeowners do not want to spend a significant amount of money on a swimming pool and only be able to use it for six months out of the year.
