We have a time share on Hilton Head Island (down the coast a little ways from Myrtle Beach) for week 51.. Usually the week between Christmas and New Year's. Taking a walk on the beach at night time requires a jacket. Most days you'll be fine wearing a sweatshirt out and about, sometimes short sleeves, but definitely not shorts weather.
We have some years where we don't get any rain all week long, some where it'll rain 4 or 5 days during the week. Kinda hit or miss.
