There was a swimming advisory in effect for 11 Jersey Shore beaches in New Jersey this week due to a bacteria found in the water. No beaches are closed and swimming remains permitted, but caution is advised, especially for children, seniors, or those with weakened immune systems. Read on for what to know about the swimming advisories that were just lifted at the Jersey Shore due to bacteria in the water.
What to Know
The bacteria, known Enterococcus bacteria, which is an indicator of fecal contamination, was alerted by NJDEP’s website, NJBeaches.org, as containing elevated levels this week.

The beaches and bay areas that were under swimming advisories as of July 22nd-23rd, 2025:
Monmouth County
- Raritan Bay Beach at the Highlands Rec Center in Atlantic Highlands
- L Street Beach on the Shark River in Belmar
Ocean County

By Thursday, July 24th, the New Jersey DEP had lifted advisories for most beaches, confirming that water quality has improved based on recent testing. However, ongoing monitoring continues at a few spots, including New Jersey Avenue Beach in Somers Point, to ensure conditions stay safe.
Enterococcus levels above the state threshold (104 colonies/100 mL) prompted advisories, which means that swimming in contaminated water can lead to symptoms like nausea, diarrhea, ear/eye irritation, and skin rashes.
Advisory, not closure, means beach access is open, but those at higher risk such as children, as well as the elderly and/or immunocompromised, should avoid swimming until tests are back within safe levels.
A few quick tips to keep in mind if swimming, as the beaches are not closed:
- Check before visiting — NJDEP updates daily at NJBeaches.org.
- Avoid swimming if you’re at higher risk until an advisory is fully lifted.
- Look for lifeguard notices and signage — they often post real-time alerts, though some visitors noted communication gaps.
- Wash off after swimming and avoid ingesting beach water.
