Traveller notes on Hilton Head Island in March
Other months in Hilton Head Island
Hilton Head's forum calls late May the sweet spot — warm enough for the beach and pool, genuinely rare to get as hot as July or August, roughly one day in four or five bringing rain, usually late afternoon or evening. Regulars note the ocean is swimmable but not warm, and that May stays noticeably quieter than the June-through-August rush since most schools are still in session.
