Suffolk County Health Services monitors bathing beaches and issues advisories when water quality may be unsafe. Beaches near streams, creeks or stormwater outfalls, and those on poorly flushed bays, ponds or lakes, are sampled once or twice a week. Lower-risk beaches such as those on the Atlantic are sampled less often.
That is why the bay beaches matter most here. A beach like Havens Beach in Sag Harbor, where a local group is working on stormwater runoff, deserves a result check before wading. Meschutt is a monitored county bathing beach.
When advisories are issued
After unusually heavy rainfall, or when other events pose a public-health risk, the county issues advisories recommending against bathing and other water contact, then samples the affected beaches to decide whether the advisory can be lifted or the beach closed. The indicators are Enterococci and E. coli, which are mostly harmless themselves but signal possible fecal contamination.
How to check
- The county updates an interactive Beach Closure and Advisory Map.
- A Beach Hotline, 631-852-5822, is routinely updated.
- At Sag Harbor, the Village posts results from the Surfrider Foundation’s Blue Water Task Force for Havens Beach, Windmill Beach and Little Northwest Creek.
What a closure means
Closures and advisories affect activities that involve water contact only. You may still walk the beach unless the local operator decides otherwise.
Practical rules
Skip swimming for a day or two after a heavy storm, keep children and pets out of standing water near outfalls, and rinse off afterward. See jellyfish and sea lice for the other water-related irritants.
