Tides & Flags

What is the water temperature?  (Temperatures taken at 9:00 am and 1:00pm)

When is high and low tide? 

FLAG SYSTEM for identifying swimming conditions:  The Ocean Rescue Department uses a colored flag system from the Department of Environmental Protection’s Management Program to identify the various levels of threat to swimmers.

What do the flags mean?

  • YELLOW – Medium hazard.  The public is encouraged to swim only in front of posted lifeguard towers/chairs.  The lifeguards can spot most dangerous rip currents and inform patrons accordingly.

  • RED – High Hazard/Restricted Swimming.  The public is encouraged to stay out of the ocean.  Even the strongest swimmers can easily find themselves in dangerous currents.  Rip currents are difficult to locate and form without typical warning signs.
