It has been a milder summer than we are accustomed to. We average eighteen days of 100 degrees or more, and this year we have only had seven. The average date for our last 100 degree day is August 26th, although we did have a 100 degree day as late as October 3rd (1951). But, it appears that 100 degree days are over for this year.
Many who like spending time outdoors are aware that fall in the north Texas area is hard to beat for weather. The average temperatures for the next three months are as follows:
- September -78 degrees (average high=88 degrees; average low=67 degrees)
- October – 67 degrees (average high=78 degrees; average low=56 degrees)
- November – 55 degrees (average high=65 degrees; average low=45 degrees)
These temperatures are ideal for being outdoors, especially in and around a swimming pool. As the ambient temperatures begin to fall this time of year, pool water temperatures also decrease to a much more refreshing level than they were in the summertime, when pool water temperatures exceeded 90 degrees on many non-shaded pools (mid-August). This time of year, the pool water temperature in most pools is in the mid-to-high 80’s, but it will gradually decrease to a much more refreshing temperature. I have found that most people prefer somewhere between 80-84, but it really depends on what type of swimming is being done. Following are brief summaries of pool water temperatures:
Warm water swimming
There are some people that like the water to be in the low 90’s before they are real comfortable in the water. Many pools in the north Texas area, especially pools without shade, reach the low 90’s in July and August.
Most casual swimming pool users like the water in the 84-86 degree range. Many hotels and resorts typically try to maintain their pool water temperature in this range.
Denton area swimming
We seem to hear quite a few comments about 80-84 being just cool enough to be refreshing, but not too warm. It might seem cold when you first get in, but then it gets comfortable.
Lap swimming for exercise
Most lap swimmers like the water temperature to be somewhere between 75-80 degrees. Being active by swimming laps will cause the body to heat up fairly quickly.
Most competitive swimmers like the water to be fairly cold, somewhere in the low to mid 70’s, depending on the intensity of the training. At these temperatures, the water will feel cold initially but once training begins, the body will heat up.
With the first average freeze date for the DFW area still months away (November 22nd), it should remain optimal for outdoor activities for at least 1-2 more months.
