Grand Strand Weather: Midweek Warmup to Precede Weekend Rain Chances

The Grand Strand will experience a gradual warmup and rising humidity this week, followed by rain chances moving into the weekend.

Why this matters locally

Rising temperatures and weekend rain chances will affect outdoor plans, local commerce, and coastal activities across the Grand Strand this week.

Grand Strand residents and coastal visitors will see a noticeable change in the weather this week as cooler morning conditions give way to rising temperatures, increasing humidity, and weekend rain chances. Following a stretch of lower humidity, mugginess will gradually build through the middle and end of the workweek across North Myrtle Beach and surrounding areas.

Clear skies and sunshine are expected to dominate through the end of the workweek, bringing a late-summer feel back to the region. Daytime temperatures will reach the lower to mid-80s along the Grand Strand beaches, while inland areas will climb into the upper 80s. Local meteorologists note that select inland locations could approach or touch 90 degrees by Thursday and Friday, with humidity reaching steamy levels by Friday.

A shifting weather pattern will arrive over the weekend as an approaching cold front moves into the Carolinas. Saturday will begin warm and humid with clouds increasing throughout the day, bringing an initial chance for scattered showers and thunder. Current forecast models indicate the cold front may slow its arrival, pushing the highest likelihood of rain into Sunday.

Sunday is expected to feature cooler temperatures, overcast skies, and periodic showers across the area. While a total weekend washout is not expected, lingering moisture behind the passing cold front will keep a chance of rain in the forecast through Sunday and into early Monday morning.

Residents, commuters, outdoor workers, and local businesses planning outdoor weekend events should monitor local updates and keep rain gear nearby for Sunday activities. Boatlers and beachgoers heading out during the late-week warmup should prepare for higher humidity levels and shifting coastal breezes as the front approaches.
