Warmed year-round by the Gulf Stream...

Hilton Head Island's average daytime air temperature is 70, and the average annual ocean temperature is 69.

Monthly averages are summarized below.

As the largest of the sea islands...

 south of New York’s Long Island and north of the Florida Keys, Hilton Head is surrounded by South Carolina’s Low Country, the former home of rice and cotton plantations.


Considered a sub-tropical climate, the moderate year-round weather is ideal for Live Oaks draped with Spanish moss, flowering Dogwoods, towering Pines and the state’s emblematic Palmetto tree.


Sea Oats cap broad white sand beach dunes and help protect them from erosion. The ocean waters are warmed year round by the Gulf Stream, which is ideal deep-sea sport fishing -- and provides a pleasant environment for outdoors sports such as golf and tennis.


Rising northward from the Savannah River, Hilton Head Island is a mosaic of golf courses, tennis courts, luxury homes and “villas” -- all dotting along a 12-miles of Atlantic beach on the east and the Intra-coastal waterway of Calibogue Sound on the east.


While some have called Hilton Head a Disneyland for adults, there is nothing frivolous about this land of plenty. Cultivating and maintaining a recreational environment and maintaining the gentle southern style is serious business here.


HHI is the land where nearly every bush is manicured to look "natural, even commercial sign design and placement  is heavily regulated -- all to minimize dissonance with natural aesthetics. Indeed, the town requires merchants even to conceal parking areas with native plantings.







What-if Sea Levels Rise, and impact South Carolina?

Human-induced "climate change" and "global warming" are fighting words on both sides of the argument. Is a weather shift really happening and, if it is, is it merely natural evolution that's happened before-or is it a transition caused by modern humans


Regardless of which side of the debate you're on, the real question is, "If the seas rise above today's levels, what happens to Hilton Head?"



Below is what scientists at Climate Central in Princeton, NJ, suggest will happen, foot-by-foot as high tides become higher.


The following maps and commentary are derived from information published by Climate Central, of Princeton, NJ, and are available  at their Website. makes no claims or declarations as to the accuracy of the Climate Central Information or our conclusions that derived from it.

+1 Foot


The non-profit organization Climate Central estimates that coastal South Carolina will experience higher high tides of 1.2 feet above current high tides by the year 2050 -- 36 years from now.


The image of that change shown at the right copied with permission from the Climate Central Website), shows the impact of a one-foot increase in high tides.


We find it interesting to note that the saltwater invasion is not from a raging Atlantic Ocean, but from the relatively docile Calibogue Sound that feds Baynard Cove, Braddock Cover, Broad Creek and Skull Creek, among other areas.

+2 Feet


At first, the one-foot and two-foot level changes on the Climate Center maps are subtle. Nonetheless, in Sea Pines Plantation, areas northwest of Sea Pines Drive begin to experience some impact of the higher water levels, according to the CC maps.


This also appears to be the case, to some degree, among abutters of Broad Creek in Wexford, Long Cove, Yacht Cove, Shelter Cove, and along the connected waterways of Palmetto Dunes.


Hilton Head Plantation and Port Royal appear largely unaffected, except for some coastal areas and tidal basins.


Ironically, the iconic Hilton Head beaches along the Atlantic, especially those in Sea Pines, appear largely unaffected.

+3 Feet


While the two-foot level basically established the locations the Climate Center suggests will experience a tidal impact, the three-foot level continues "more of the same."

+4 Feet


According to the Climate Change "experts," few of us living today will have to worry about the four-foot level because that won't occur until the year 2100, or 86 years from now; if ever, we might add.


That said, however, if CC is correct, the south end of the island, Sea Pine in particular, will experience serious tidal impact, as will the south side of Broad Creek.


The areas around Skull Creek and Windmill Harbour will see some impact, based on the CC projections. Hilton Head Plantation and Port Royal continue to experience only minor impact, except in their immediate coastal areas and tidal basins.

+5 Feet


At five feet, much of the south and west portions of the island are inundated at high tide, according to the Climate Change report.


The remaining areas above water at high tide appear to be in the vicinity of Indigo Run extending west to Spanish Wells. Also spared are virtually all of the margins of William Hilton Parkway, the airport, Hilton Head Plantation and much of Port Royal.


The Climate Central projections take the high-tide level all the way to 10 feet not pictured, but on their Website), which must be 'way far' out in time, and by then only portions of Hilton Head Plantation, Indigo Run and Spanish Wells prevail.
