North Texas sees fewest 100-degree days in meteorological summer since 2007
North Texas just saw its lowest number of 100-degree days in meteorological summer in nearly two decades.
Meteorologists break the seasons into three-month groupings, with the summer season being from June 1 to Aug. 31, according to the National Weather Service. This method was made to mirror the actual calendar and stay consistent, as each season lasts around 90-92 days.
In total, the Metroplex saw six days over triple digits during this year’s meteorological summer.
This is the lowest number of 100-degree days in a meteorological summer since 2007, when North Texas recorded five days over triple digits, according to NWS climate data. Those five days were the total number of 100-degree days in the year.
2025’s meteorological summer
The average temperature for meteorological summer this year was 84.5 degrees, which ranks as the 39th warmest summer on record out of 127 summers, according to the NWS.
North Texas recorded its first 100-degree day on July 29, which was the latest first occurrence of triple digits since 2019, when the temperature was recorded on July 30.
Here’s a look at the other five days of triple digit heat this summer:
- July 30- 101 degrees
- July 31- 104 degrees
- Aug. 18- 101 degrees
- Aug. 19- 103 degrees
- Aug. 28- 100 degrees
There are a couple factors as for why the Metroplex had a cooler summer this year.
Having more rain in the spring and wetter soils going into the summer helped stave off 100 degrees, according to the NWS. North Texas recorded more than 9 inches of rain in April (5.22) and May (4.51) this year.
Another factor for keeping the heat at bay was the distance from where an upper-level ridge pattern sits up for the summer.
An upper-level ridge is like a dome of high pressure and warm air, also known as a “heat dome,” according to the NWS. Parts of the state have felt the effects from a “heat dome” this year, including areas in East and South Texas.
The Metroplex was on the edge of a “heat dome” in early June and felt temperatures in the low 90s.
What to expect in meteorological fall
Meteorological fall began on Sept. 1 and lasts until Nov. 30.
The NWS’ Climate Prediction Center’s three month outlook, issued on Aug. 21 and valid from September through November, predicts a 40-50% chance for above-normal temperatures.

The normal high for September is 88.6 degrees, followed by 78.4 degrees in October and 66.6 degrees in November, according to NWS data.
Above-normal temperatures doesn’t always equate to extreme heat, according to the NWS. Instead, above-normal could simply mean temperatures are a few degrees above the normal parameters.
For precipitation, the CPC’s outlook predicts a 33-40% chance of below normal precipitation over the fall months.
While this is a snapshot of how things are expected to look in the future, a one month outlook and subsequent weeks’ and days’ forecast will give a better look at what to expect as the date grows near.
