Why September Cold Fronts in Texas Tend to Be Weak
US · Published Sep 25, 2025
September cold fronts in Texas are usually weak, with only a slight drop in daytime highs.
The weak polar jet stream, positioned far north, is the main reason for the mild fronts.
Stronger cold fronts are expected later in the fall as the jet stream strengthens and moves south.
September's underwhelming cold fronts in Texas
September in Texas often brings the anticipation of cooler weather, but the cold fronts that arrive this month tend to be underwhelming. Unlike the strong, crisp fronts of late fall and winter, September cold fronts typically offer only a modest respite from the lingering summer heat. Daytime highs might dip by a mere 5–10°F, hardly enough to warrant breaking out the sweaters.
