Grand Strand to see record warmth before sharp weekend cooldown

Grand Strand residents and visitors can expect a dramatic shift in weather over the coming days, transitioning from near-record heat and high humidity through Friday to crisp fall conditions over the weekend.

On Thursday, October 15, afternoon temperatures along coastal beaches are expected to reach the mid-80s, while inland areas could climb to the upper 80s or near 90 degrees. These unseasonably warm conditions put daily temperature records in jeopardy across Myrtle Beach, Florence, and Lumberton.

The unseasonable warmth will continue into Friday, October 16, with mid-80s expected along the Grand Strand and upper 80s inland. Mild and humid conditions will linger into the evening, providing pleasant weather for fans attending the Coastal Carolina University football game against Appalachian State at Brooks Stadium in Conway.

A cold front is scheduled to push through the region late Friday night, bringing a sharp temperature drop for the weekend. High temperatures on Saturday, October 17, and Sunday, October 18, will cap out in the mid-to-upper 60s.

A low-pressure system developing off the Atlantic coast will introduce extra cloud cover, brisk winds, and a chance of passing light showers on Saturday. While a washout is not expected, residents planning outdoor activities on Saturday should keep a light jacket handy and monitor local updates, as small shifts in the offshore system will dictate rain chances. Clearer skies will return by Sunday, bringing the coolest morning of the season with lows dipping into the 40s before reaching the mid-60s in the afternoon.
