Please see the below message from Delaware Department of Health and Social Services (DHSS):
If you're headed to the beach for the day or the week, remember to stay at least 6 feet apart from people not in your immediate family, pack your hand sanitizer, face mask and sunscreen, and enjoy the high temperatures in the mid-80s today.
