High Humidity and Thunderstorm Chances Return to the Grand Strand This Weekend

High humidity and warm conditions are returning to the Grand Strand area this weekend, bringing a renewed chance for summer thunderstorms across the coastal region. After a brief period of drier air, tropical moisture is shifting back north, setting up a classic August weather pattern for local communities.

Overnight conditions across North Myrtle Beach and surrounding areas are expected to stay mostly clear, warm, and muggy, with low temperatures holding in the mid-to-upper 70s. As moisture levels build throughout the weekend, humidity will rise noticeably during the day, making heat index values feel higher than the ambient temperature.

The return of atmospheric moisture will also bring scattered afternoon and evening thunderstorm chances back to the region. While rain is not expected to be continuous, pop-up storms can develop quickly during the warmest parts of the afternoon, potentially producing brief heavy downpours, lightning, and localized gusty winds.

Residents, weekend visitors, outdoor workers, and beachgoers should plan around the high heat and humidity. Those spending extended time outdoors are advised to stay hydrated, take frequent breaks in shaded or air-conditioned spaces, and keep an eye on changing sky conditions. Boaters and swimmers should monitor local weather updates and be prepared to seek shelter if lightning or dark clouds approach coastal waters.
