May weather in Myrtle Beach is often suitable for the beach, although many people visiting from other parts of the South find the water too cold for swimming on all but the hottest days (visitors from the North often find it very agreeable). Boat rentals, kayak tours and other watersports are becoming popular at this time of year.
In general, pack for hot weather, with shorts and short-sleeved shirts (and a bathing suit just in case), but also bring some light additional layers for cooler evenings. Bring sunscreen, a hat and an umbrella too. In May, it can still be possible to have runs of quite cool days, so check the forecast before your visit, and pack accordingly if so.
