Temps are running above average, but when can San Antonio expect to hit 100°?

FORECAST HIGHLIGHTS

  • STILL RAIN-FREE: Pattern stays quiet into next week
  • WHEN DO WE HIT 100°?: We average our first 100° day in June

FORECAST

I’ll keep this short and sweet, as we’ve hit yet another dry spell. The biggest takeaway for the next seven days will be the fact that despite some weak fronts moving through, we’ll running some 5-10° above average. Expect a breezy weekend, too.

AVERAGE FIRST 100° DAY IN SAN ANTONIO

If you look over the past 30 years, San Antonio’s average first triple digit day falls in late June. But, know that this is just an average. We’ve seen triple digits as early as February (1996) and in 2021, we didn’t see a 100° day until September. If I we’re a betting man, I’d expect it to happen sooner rather than later this year.
