Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Average Rainfall in August

August is one of the wettest months of the year in Myrtle Beach, with an average of 5.58” of rain and an average of 13 days of rain.

Sure, you may sweat a little in August, but who doesn’t expect that during summertime? The hottest day on record in Myrtle Beach was on August 22, 1983, with a record high of 105°F. That was quite a while ago, though, so you shouldn’t have to worry about scorchers like that while you’re in town.
