Nearly 30 Massachusetts beaches are closed to swimming on Wednesday, July 22, 2026, after water tests showed high bacteria at coastal and inland sites across the state. The Massachusetts Department of Public Health posts those results on its interactive beach water quality dashboard, and MassLive compiled the day list for travelers who need a fast check before they leave for the shore.
A posted beach is not automatically empty of people, and sand sports or shoreline walks can still be allowed. The traveler decision is simpler and more urgent: stay out of the water where the dashboard shows a swimming closure, then recheck before the next beach day because the list can change as new samples clear or fail.
- Advisory day: Wednesday, July 22, 2026, with a state list of nearly 30 closed beaches.
- Primary cause: Bacterial exceedance at most posted sites, not a statewide storm shutdown.
- Traveler action: Do not swim at posted beaches; onshore recreation may still be allowed.
- Official tool: Massachusetts DPH interactive beach water quality dashboard.
- Who should care: Day trippers, hotel guests, and families planning Cape Cod, North Shore, and inland lake stops.
What the July 22 list actually means
MassLive reported that nearly 30 beaches are closed across Massachusetts on Wednesday, July 22, including coastal and inland locations. High bacteria levels forced most of those postings, according to the state dashboard that local health agencies feed with sample results.
That distinction matters for planning because this is not a single park gate that flipped closed. It is a set of water quality postings that can leave neighboring beaches open while one cove, pond, or town beach stays off limits for swimming until retesting clears it.
MassLive named towns that include Amherst, Ashby, Ashland, Barnstable, Beverly, Dartmouth, Duxbury, Holden, Lanesborough, Middleborough, North Andover, Quincy, Salem, Springfield, Swampscott, Swansea, Templeton, Tisbury, Wareham, and Winthrop. Travelers should treat that published list as the day snapshot, then confirm their exact beach name on the dashboard before packing float toys or planning a swim break.
Several Salem sites appear on the same day list, which is a useful reminder for North Shore visitors who may bounce between town beaches and heritage stops. If swimming is the goal, choose a confirmed open beach instead of assuming a famous town name equals open water.
How Massachusetts beach postings work
The state interactive beach water quality dashboard is the primary traveler tool. It shows whether a beach is open or posted with a no swimming advisory, along with location and water type details that help you match the name on the sign to the name on the map.
Sample based postings are not always instant because local programs collect water and laboratories process the results. Postings remain until analysis shows bacteria levels are back within limits, so a beach can stay closed for a day or more after the weather that drove the spike has already improved.
Massachusetts recreational water guidance explains why the risk is real even when the water looks inviting. Swimming in water with elevated bacteria can lead to nausea, vomiting, diarrhea, abdominal pain, sore throat, cough, or skin rashes, according to the state Department of Public Health recreational water materials.
Posted beaches can still support dry land plans. The department notes that visitors may still use a posted shoreline for non contact activities such as walking, sunbathing, or sports that keep people out of the water.
Where the July 22 closures cluster for travelers
The day list spans more than one tourist corridor. North Shore travelers will notice multiple Salem entries, plus Beverly, Swampscott, and Winthrop, while South Shore and South Coast visitors should check Duxbury, Quincy, Dartmouth, Swansea, and Wareham before committing a whole afternoon to one named beach.
Cape and Islands travelers are not outside the risk. Barnstable Keyes Beach and three Tisbury locations appear on the MassLive Wednesday list, which is a direct planning flag for Vineyard day trips and mid Cape lodging stays that treat swimming as the default afternoon plan.
Inland travelers face the same rule because pond and reservoir postings in Amherst, Ashby, Ashland, Holden, Lanesborough, Middleborough, North Andover, Springfield, and Templeton show that freshwater destinations can close for bacteria just as ocean beaches do. A quiet Berkshires or central Massachusetts lake stop still needs the dashboard check.
If your Massachusetts itinerary already includes coastal heritage stops, you can keep the day useful even when swimming is off. Deep Arrival’s Salem Maritime National Historical Park guide is a practical alternative for visitors already on the North Shore, and the Cape Cod National Seashore guide helps reframe a Cape day around open trails, visitor centers, and shoreline walks when a specific town beach is posted.
How to plan the next 24 hours
Start with the exact beach name, not the town name alone. Several towns have more than one monitoring site, and a closed cove does not automatically close every nearby stretch of sand.
Next, decide whether the trip still works without swimming. Families who need water contact should move to a dashboard confirmed open beach or switch to a pool, while walkers and photography travelers can often stay put on dry sand under the posted rules.
After heavy rain, raise your skepticism even before a formal posting appears. Runoff can push bacteria into ponds, rivers, and near shore ocean water, and the lab cycle can lag the weather by a day.
Avoid swimming near trash, discolored water, strong odors, or storm drains, and do not swallow beach water. Those practical rules matter even when a neighboring site is still listed as open.
If you are lodging near a posted beach for multiple nights, build a morning dashboard habit. Closures can clear after retesting, and a beach that was closed Wednesday may reopen once bacteria falls below the standard.
Parents and group leaders should treat the posted list as a hard no for water entry, including wading. That includes diapered children and anyone who is already ill, both of which increase contamination risk if people enter the water anyway.
| If you… | What to do |
|---|---|
| Planned a swim at a named town beach on July 22 | Match the exact site on the DPH dashboard and skip the water if it is posted closed. |
| Need water play for kids today | Choose a confirmed open beach or a pool instead of hoping a posted shoreline is fine for wading. |
| Want a North Shore or Cape day without swimming | Keep the trip, stay on sand or heritage routes, and use dry land stops around the same towns. |
| See rain in the forecast tonight | Recheck the dashboard tomorrow morning before returning to the same beach. |
| Find your beach open but water looks off | Skip swimming near trash, strong odors, or storm outflows even without a formal posting. |
- Before you leave: Search the exact beach name on the state dashboard, not only the town.
- At a posted site: Stay out of the water, including wading and splash play.
- Backup plan: Keep onshore walks, parks, or nearby open beaches ready if swimming was the main stop.
- Multi day stays: Recheck each morning because sample based postings can clear after retesting.
- After rain: Expect lag between storms and updated lab results before assuming conditions improved.
Wednesday’s list is a live operational warning for summer travelers, not a permanent judgment on Massachusetts beaches. Use the dashboard as the authority for the next decision, treat posted water as off limits, and keep the rest of the coastal itinerary flexible enough to move to open sand, inland parks, or heritage stops without losing the day.
How many Massachusetts beaches are closed on July 22, 2026?

Where do I check current Massachusetts beach closures?
Use the Massachusetts DPH interactive beach water quality dashboard for the latest open or closed status by beach name.
