High Humidity and Daily Afternoon Storms Forecast for Grand Strand Weekend
High humidity and daily afternoon thunderstorm chances are expected across the Grand Strand and Pee Dee regions through Sunday, September 13.
Why this matters locally
High humidity and afternoon downpours may affect beachgoers, outdoor workers, local traffic, and weekend crowds attending events like the Coastal Carolina home opener.
Residents and visitors across the Grand Strand and Pee Dee regions should prepare for elevated humidity and daily afternoon storm risks through Sunday, September 13, 2026.
On Friday afternoon, high temperatures are expected to reach the mid-80s along coastal beaches and the lower 90s inland. High humidity levels will make afternoon conditions feel like the mid-to-upper 90s before precipitation develops. Scattered showers and thunderstorms are expected to form first near coastal beaches shortly after lunchtime before moving inland through the early evening. Rain chances are set at 40%, with select storms capable of producing frequent lightning and locally heavy downpours.
Elevated humidity will remain across the region through the remainder of the weekend. Daytime high temperatures will hover in the mid-80s along the Grand Strand and in the upper 80s across the Pee Dee area. While clouds and afternoon storms will build each day, morning sunshine is expected before rain opportunities peak in the afternoon hours.
Local officials and forecasters advise that weekend outdoor plans do not need to be canceled, but attendees should remain alert and have quick access to indoor shelter. For fans attending the Coastal Carolina University football home opener on Saturday night, storm chances are expected to decrease by kickoff, though isolated rain remains possible early in the evening. Outdoor workers, weekend commuters, and beachgoers should monitor local conditions and stay prepared for localized heavy rain.
