SAN ANTONIO, Texas – Early fog blankets the Hill Country this Sunday morning, softening the skyline and leaving a fine dew on windshields and lawns. The haze will lift quickly, revealing another stretch of blue-sky warmth — a pattern that will dominate much of the upcoming week before a late-October cooldown finally moves in midweek.
According to the National Weather Service in Austin/San Antonio, patchy fog could reduce visibility along I-35 and U.S. 281 through midmorning. Once the mist clears, temperatures climb rapidly into the mid-80s under mostly sunny skies. Winds stay light and variable today, offering calm conditions for outdoor plans, markets, and travel.
By Monday and Tuesday, high pressure keeps the region dry and warm. Afternoon highs could reach 88°F, approaching record territory for late October. South winds return, nudging humidity levels higher, especially east of the city toward Seguin and Gonzales. Those driving or working outdoors should stay hydrated as heat builds across central Texas.
A noticeable shift arrives Wednesday as a cooler air mass slides south from the Plains. Gusty north winds up to 25 mph will usher in drier, more comfortable air with highs dropping into the low 70s. Nights will turn crisp, with lows in the 40s and 50s — a welcome change for fall enthusiasts and early Halloween decorators.
Trick-or-treat conditions Friday look nearly perfect: clear skies, light winds, and temperatures in the upper 60s by sunset.
After a warm finish to October, early signs suggest a chillier November ahead, with the first real taste of fall air deepening next weekend.
