CLIMATE CONTEXT
San Antonio has already seen a couple of “cold fronts” this fall, but they’ve mostly fizzled out before delivering real relief. Locals are still waiting for that first true cold front that sticks around for more than a day.
October 2025 is shaping up to be one for the record books. We’re on pace to challenge the all-time record for most 90° days in October (19 days set in 1947) and could end up with the warmest October on record.

LOOKING AHEAD
Medium-range models are still at odds over how the weekend trough evolves. Some suggest a more organized low could develop, but confidence remains low. Beyond Sunday, the pattern may finally shift as a series of troughs approach from the west coast. This could bring better rain chances and a more substantial cold front by late October.
