Weather by month
Myrtle Beach
South Carolina
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.
The best time to come
May and October are the ones to circle: warm enough for the water, quiet enough to park. September splits the difference — the ocean is still summer-warm and the crowds are gone, but it is also the month the tropics are most likely to interrupt.
