By mid to late May, the gradual warming makes longer shoreline experiences more pleasant, especially on sunny days with light winds. Layering with a light rash guard or thin wetsuit can extend comfort for water sports enthusiasts.
Keep an eye on local forecasts, as onshore winds can sometimes cool surface waters temporarily while sunny stretches push temperatures toward the higher end of the monthly average.
What to Wear in May
For most visitors, Myrtle Beach water temp in May suggests light to medium coverage swimwear paired with a quick-dry towel or cover-up. Morning and evening breezes often make a light jacket or windbreaker necessary on the sand.
Water shoes are helpful on shell-filled walkways and rocky patches near certain access points, while sunscreen remains essential even when air temperatures feel moderate. Swimmers who are sensitive to cooler water might opt for a shorty wetsuit or thermal top during extended sessions.
Activities and Water Comfort
Gentler temperatures in late May align well with swimming, paddleboarding, and beginner-friendly surfing lessons. Anglers appreciate calmer conditions and improving water clarity as the month progresses, while wildlife watchers enjoy active shorebird flocks along the surf zone.
Families with children often target the third week of May and beyond, when warm air and steadily rising water create a forgiving environment for first ocean experiences. Plan indoor backups for cooler days, such as the boardwalk arcades, museums, and local dining options.
