Are lifeguards on duty on 30A after October?
No. South Walton Fire District staffs 19 towers from March 1 through October 31, 10 a.m. to 6 p.m. daily. After that, coverage is limited roving patrols. Text SAFETY to 31279 for current flags. Double red means the Gulf is closed, and entering can bring a $500 fine. On west 30A, the Dune Allen and Ed Walline regional accesses have seasonal towers.
Where do you warm up after a November swim?
Inkwell Manor is a standalone two-bedroom house in Santa Rosa Beach, from $250 a night. The full kitchen means a hot lunch without driving anywhere in a wet swimsuit.
A private hot tub and fire pit handle November evenings, which average 53°F. See the house or book on Airbnb.
