First responders were called to the beach just before 12:40 p.m. on reports of possible drownings. Bystanders had pulled two people from the water before police and EMS workers arrived.
Both victims, a 22-year-old man and a 21-year-old woman, died at a hospital.
Much of the Lake Michigan shoreline, including South Haven, was under a swimming alert Monday. The National Weather Service advised people not to swim in the water from St. Joseph to Ludington because of the potential for waves that could reach 7 feet, and heavy currents.
There have been numerous drownings and near drownings in Lake Michigan this summer.
