A beach advisory leaves it up to users as to whether they wish to risk going into the water. In the case of a beach closure, the state and/or local government decides that water conditions are unsafe for swimmers and other users.
How can beach-goers avoid the disappointment of arriving at their summer vacation destination only to find that authorities advise them not to swim there or that the beaches are closed altogether?
Unfortunately, there is no central database that provides information on beach closures and advisories in real time. The best way to find information on the current water quality of a particular beach is to plan ahead.
