Mostly sunny conditions today, with warm afternoon high temperatures in the upper 80s to mid 90s. There is a very low chance (10%) of isolated afternoon showers across the Coastal Plains, I-35 corridor, and Hill Country, however most locations will remain dry.
The remainder of the week and into the weekend will be unseasonably warm with high temperatures consistently in the 90s for most. There are very low chances (10-20%) of isolated afternoon showers through the weekend, however most locations will remain dry.
This upcoming October will likely be warmer than normal across South-Central Texas. Odds are also tilted towards less rainfall than normal for the month.
The combination of drier and warmer than normal conditions in October will likely lead to an expansion and worsening of the ongoing drought over our area. Severe to exceptional drought is already impacting most of much of South-Central Texas, especially the San Antonio area, areas along Highway 90, and adjoining portions of the I-35 corridor and Coastal Plains.
A typical October in South-Central Texas features temperatures cooling throughout the month as cold fronts begin pushing across the area, with moisture from Pacific storms occasionally adding rainfall. Average highs cool from the upper 80s to the lower 80s and upper 70s, but a few highs in the 90s are typical. Average lows cool from the 60s to the 50s. October freezes do happen every few years in the Hill Country but are much rarer elsewhere. However, the outlook for October 2025 indicates this month will likely feature warmer than normal temperatures with chances tilted towards drier than normal weather.
