SAN ANTONIO – We’ll be feeling the effects of Wednesday’s cold front all the way through the upcoming weekend, which bodes well for any Halloween plans you might have! 🎃 Whether you have a costume party to attend or some serious trick-or-treating to do, here’s what you need to know:

  • SATURDAY: After a morning in the 40s, we’ll warm up to near 80° in the afternoon under sunny skies. Even as it gets a little warm, humidity will still be low. If you’ll be heading out for any festivities Saturday night, expect cool and crisp conditions with temperatures falling through the 60s.

  • SUNDAY: After another cool morning, our high temperatures will be in the low 80s to mid 80s on Sunday. A light wind out of the ESE will begin to bring some humidity back, but it’ll still feel really nice. Aside from a few clouds here and there, skies will remain clear. Look for temperatures to fall through the 70s and into the 60s during Trick-Or-Treating time. 🍬

Halloween Climatology

While we’re in for nice weather this year, Halloween has proven to be a bit of a weather wild card in the past! We’ve been as hot as the upper 80s and as cold as the upper 20s. There have also been plenty of years with rain in the forecast since this is the time of year when cold fronts start to move through with more consistency.
