It's hot in Myrtle Beach, so a lot of people are cooling down in the 82-degree big blue! 🌊☀️ Residents and visitors were treated to this Carribean-like blue color earlier this week! It comes around a few times a year. With heat indexes expected to be up to 109 in the Myrtle Beach area this weekend, here are some things to keep in mind: - Always swim near a lifeguard. - Drink plenty of water. - Limit time in the heat. Take frequent breaks in air conditioning. - Wear loose clothing if outside. -
