Spring (March–May) is the peak demand period for billboard advertising in Charleston. The Cooper River Bridge Run, Charleston Wine + Food Festival, Spoleto Festival USA, and Historic Charleston Homes and Gardens tours draw the highest visitor volumes of the year. Summer (June–August) brings peak coastal traffic to Isle of Palms, Sullivan’s Island, and Folly Beach. Fall (September–November) is the primary window for real estate, corporate relocation, and financial services campaigns across the growing Summerville and Goose Creek corridors. The year-round port-logistics and manufacturing workforce anchored by Boeing, Bosch, Mercedes-Benz Vans, and Volvo Cars sustains consistent billboard demand along I-26 and Dorchester Road. The winter off-peak window (December–February) is the best time to negotiate rates and secure preferred positions. Book 4–6 weeks in advance for standard placements. Peak spring positions on I-26 and US-17 should be secured 8–10 weeks ahead.
