September weather forecast
Texas, USA

September marks the gradual transition from the intense summer to the more temperate fall in Texas. In the northern areas, such as Seminole, the influence of the upcoming fall becomes gradually noticeable. Mornings commence with a cooler 65°F (18.3°C), and while afternoons can still be warm, temperatures usually peak around 90°F (32.2°C).

Central Texas, with its vast terrains, starts to witness a reprieve from the relentless heat of the preceding months. Dawn temperatures typically rest at about 75°F (23.9°C), and by midday, it's common for the mercury to reach the high 90s°F. The southeastern coastal stretch, influenced by the Gulf of Mexico, experiences a temperature spectrum from 78°F (25.6°C) in the mornings to highs of about 95°F (35°C). However, the drop in temperature also means a decrease in the oppressive humidity that characterizes the peak summer months.

September sees increased chances of rain, particularly in the eastern parts of the state. These showers, while more frequent than the summer months, tend to be moderate and are interspersed with clear days. Thunderstorms, while less intense than in the peak summer, can still be witnessed, providing brief respite from any lingering heat.

Moving from August to September, Texas begins to cool down, signaling the slow retreat of summer. While the start of September can still feel much like the tail end of summer, the month's progression brings with it the promise of cooler days. As September draws to a close and October emerges on the horizon, Texas readies itself for the more consistent cooler temperatures and the charm of the fall season.
