A single row can hide a real spread — open a month to see it region by region.
Charleston & the Lowcountry
- Charleston Charleston keeps a subtropical schedule: a spring that goes on for months, a summer that settles over the peninsula like a wet towel, and a winter that barely bothers showing up.
- Hilton Head Island Hilton Head keeps two speeds: a long soft shoulder season made for bikes and tee times, and a summer thick enough that you plan around the middle of the day.
The Grand Strand
- Myrtle Beach Myrtle Beach lives by the season — a long warm stretch when the whole Grand Strand is awake, and a cool, half-shuttered winter when most of it isn't.
