I get out MI for the last 2 weeks of the year. Myrtle Beach has ben the destination for about 15 years. Had snow on Christmas a few years back which was really weird looking. Had Ice storm about 10 years back. Most of the time I would guess the average daytime high is low to mid 60's. Down to low to mid 40's at night. Never know the prevailing weather pattern but last year was great with only 1 rain day and most days sunny and upper 60's - low 70's. Check some of the weather site for more information. Nice enough to walk the beach most days and go shopping or to a show if weather isn't great. Indoor pool at Ocean Lakes so another thing to do. Randu
