January Hilton Head Island Weather

The first month of the year still brings bouts of blustery winter weather to Hilton Head Island. 

With Hilton Head Island’s subtropical climate, it’s still nice enough to get outside and explore the fantastic Lowcountry landscape. More temperate than most coastal destinations, expect a little more cloud cover than usual in January.

Crisp, bluey skies characterize South Carolina winters. Other than a day a few days of rain, you can expect mostly mild temperatures and dry weather. Pack for cool to mild temperatures, dress in layers, and prepare to get cozy by the fire. Layer up for star gazing on the beach.

Intermittent periods of rainfall are common during January at Hilton Head Island, with approximately 10 days of rain and three storms. Take a spa day, explore the Island’s many shops, take in local culture at a show or gallery, or simply watch the rainfall from the window of a cozy cafe.

Expect cloudy skies for most of January on the Island, with approximately 9 days of mainly clear skies and a little over 10 hours of light a day.With a little over 10 hours of light a day, the mostly dry and mild weather still allows for plenty of outdoor exploration. Bundle up and walk the beach, take a bike ride along 60 miles of multi-use trails, and experience Hilton Head’s past at its many historical sites.

With bouts of precipitation, the humidity on the Island remains relatively high at around 82 percent in the mornings, dropping to 52 percent by late afternoon. Prepare for January’s changing temperatures by dressing in layers to stay comfortable while you explore Hilton Head Island.
