Hilton Head Island, located in South Carolina, has a subtropical climate which means it experiences mild, relatively warm winters and hot, humid summers. Here’s what you can expect:
Spring (March – May): Temperatures start to climb into the 70s°F (around 20s°C), making it an ideal time to enjoy outdoor activities without the intense summer heat. This season also witnesses the RBC Heritage golf tournament, a notable event on the island.
Summer (June – August): This is the hottest time of the year, with temperatures reaching the high 80s°F to low 90s°F (30s°C). This is also the busiest season as families visit during school vacations. It’s a great time for beach activities but do note it can be quite humid and there is a higher chance of rain.
Fall (September – November): Fall sees temperatures ranging from high 70s to low 80s°F (25-28°C) in September, cooling down in October and November. The humidity drops, making it an ideal time for outdoor activities. This is also the time for the annual Hilton Head Island Concours d’Elegance & Motoring Festival.
Winter (December – February): Winters are mild with temperatures in the 50s-60s°F (10s-20s°C). It’s the off-peak season, so it’s less crowded, but not all services and attractions might be open or they may have limited hours.
So, the best time to visit really depends on what you’re looking to do. For beach and water activities, summer is the best time, though it can be crowded. For golf, tennis, biking, and general outdoor activities without the extreme heat, spring and fall are ideal. If you prefer a quieter vacation and don’t mind cooler temperatures, winter could be the right choice.
