SAN ANTONIO, TX – Dawn breaks hazy and still across the Hill Country, with faint fog curling above low fields and quiet neighborhoods. The warmth that has lingered since the weekend won’t last much longer—change is coming fast.
According to the National Weather Service in New Braunfels, patchy fog may linger through 8 a.m. before skies clear under another round of upper-80s warmth Monday and Tuesday. However, a strong north wind Tuesday night will deliver a sharp drop in temperatures as a fall cold front moves through South-Central Texas. Gusts may reach 35 mph along I-35 and Highway 90, and light debris could scatter across open stretches before calmer, cooler air settles in Wednesday morning.
Wednesday’s highs will hold near 70°F, almost 20 degrees lower than Monday’s, with crystal-clear skies and brisk afternoon breezes. The crisp pattern continues through Friday, offering perfect conditions for outdoor work, early decorating, or high school football under clear autumn skies.
Thursday and Friday bring mild afternoons in the mid-70s and chilly dawn lows in the upper 40s to low 50s. That comfortable stretch leads directly into a near-perfect Halloween setup—cool, calm, and dry, with light evening winds and clear visibility for trick-or-treaters across Bexar County and beyond.
Looking further out, early November signals a more seasonal rhythm: sunny days, cooler nights, and hints of a chilly November ahead for Central Texas.
