Charleston Weather Discussion

The latest forecast and discussion for the Charleston, SC metro area

Thursday: Another unseasonably warm day; maybe an afternoon storm

Jared Smith / September 24, 2025 at 7:21 PM

After hitting 91° on Wednesday, we look to take another trip to the 90s on Thursday as ridging aloft combines with Atlantic high pressure to keep us well on the warm side of normal for another day. Temperatures start in the low to mid-70s, well above normal for this point in the year, warming to the 90s in the afternoon with heat indices making it feel more like the mid-90s. We could see a stray shower or thunderstorm in the afternoon and evening along and ahead of the seabreeze, but most of us should stay dry.
