Hilton Head Weather in April
The shoulder-season sweet spot. Heritage week is the asterisk.
April is one of the best months on Hilton Head, with one large caveat: the second week. The <a href="/blog/rbc-heritage-2026-travel-guide">RBC Heritage tournament</a> April 13-19 doubles rates and packs the island. Outside that week, April delivers 74°F afternoons, blooming dogwoods, dry weather, and quiet beaches.

What April feels like on Hilton Head
By week 1, the island is genuinely warm. Sunscreen weather. Locals start eating dinner outside again. Late afternoons hit 75-78°F. By Heritage week, energy is at fever pitch — plaid jackets, corporate hospitality tents, scoreboard cheers from Harbour Town. The week after Heritage feels like the calm after a storm and is one of the best weeks to be on the island.
Yes for weeks 1, 3, and 4. Yes for Heritage week if you're attending the tournament; no otherwise (rates double, restaurants overwhelmed, traffic surges). For a golf trip, late April is course-conditioning peak. For Easter, book 4-5 months ahead.

- Should I visit during the RBC Heritage?
- Yes if you're attending the tournament — it's one of the best PGA Tour weeks of the year. No if you want a normal Hilton Head trip; rates double, restaurants overwhelmed, and Harbour Town is restricted. See the Heritage travel guide.

- Kids yes by mid-month, adults mostly no. Water averages 67°F in April, warming fast through the month. By late April early-season swimmers are in; by Mother’s Day weekend, it’s swimmable for nearly everyone.
