CHARLESTON, S.C. – A perfect stretch of fall sunshine continues across coastal South Carolina, but a noticeable cool snap is on the way by Friday morning. Residents across Charleston and along the I-26 corridor will wake to crisp, dry air that ushers in one of the most comfortable weekends of October.
According to the National Weather Service in Charleston, highs will remain in the 70s through Thursday before dropping near 70 degrees Friday. A light north breeze will keep humidity low, ideal for fall outdoor plans — from pumpkin patch visits to beach walks. Skies will stay mostly clear, offering prime conditions for early leaf viewing across the Lowcountry and up toward Summerville and Moncks Corner.
Drivers along U.S. 17 and I-26 can expect bright, glare-prone conditions through the week, so sunglasses and extra caution during morning commutes are advised. With the weekend expected to remain dry, it’s a great window for home maintenance, decorating, or local harvest festivals before the next round of showers early next week.
Charleston County Emergency Management reminds residents to hydrate and protect pets from cooler nighttime lows dipping into the mid-50s by Friday night. The region’s mild stretch should last into early next week before slightly warmer temperatures return.
