March Hilton Head Island Weather

Spring comes early along coastal South Carolina. Visitors to Hilton Head Island during March can expect mild and mostly dry temperatures as the seasons change.

Over the month of March, the temperature on the Island steadily increases from a minimum low of 48 degrees to highs of 68 degrees during the day.  Be treated to a few rare days of 80 plus degree weather, but be aware, nights are still on the chilly side.

Take advantage of the remaining days of Hilton Head’s offseason. Live like a local and hit the greens before the opening season rush. Raise a glass to the budding patio season. Treat yourself to luxury Lowcountry accommodations at low season prices. When it comes to Hilton Head in March, the early bird definitely gets the worm.

Like February, Hilton Head Island receives 8 to 9 days of rainfall during this month, so plan ahead. Be sure to include a day or two of drizzly weather activities in your travel itinerary.

Days are getting longer and sunnier on Hilton Head Island as we ease into the spring season. Over 11 hours of daylight and overcast to clear skies welcome outdoor explorations. Horseback riding, sea kayaking, and bird watching are all great activities for March’s mild to warm temperatures.

The sun is shining, the weather is warm, and South Carolina’s characteristic humidity takes a bit of a break during March. With peak humidity dropping from 85 to 83 percent in the morning and plummeting further to a comfortable 48 percent by late afternoon. Play a game of pickleball with friends, run along the sands, or hit the trails on a bike—it’s the perfect weather outdoor physical activity.
