Before you get in
A red flag means do not go in, whatever this page says.
If you get into trouble, float on your back until the cold shock passes. Full advice below.
In an emergency call 999 and ask for the Coastguard, or 112 in the Republic of Ireland.
Water quality today
The last fortnight
What this verdict covers
Independent site, not an official one. This verdict is about water quality. It does not tell you whether the water is safe to get into today.
How it has been rated
The annual classification for 2021 to 2025. Each one is calculated from samples taken over up to four bathing seasons, so these overlap and none of them describes today.
Every sample, 2024 to 2026
45 samples, 2024 to 2026. The highest E. coli count in them was 530 per 100ml, on 10 June 2026; the standard for Excellent is 250 or below and for Good 500 or below.
One bar for each sample, oldest on the left. The taller the bar, the more E. coli that bottle held.
The scale is the same on every beach on this site, which is why a clean beach looks flat — the bars are measured against the standard rather than against that beach’s own worst day. Hover or tap a bar for that day’s figures. A single count over a line is not a failed beach. The classification is worked out as the 90th and 95th percentile of four years of samples, so one bad morning does not decide it — and one good morning does not either. 1 of these is above the Good standard, so it is pinned to the top with a notch rather than the chart stretching to fit it.
What these bacteria mean for you
Neither one is what makes people ill by itself. They are markers: they live in the gut, so finding them means sewage or animal waste has reached the water, and whatever else came with it is likely there too.
The usual way to catch something is swallowing the water, and the usual result is a stomach upset. Ear, eye, chest and skin infections are the other common ones. Putting your head under and swimming with an open cut both raise the odds.
The riskiest time is the day or two after heavy rain, when storm overflows discharge and rain washes off farmland — including at beaches rated Excellent for the rest of the season. That is the whole reason this page shows you rainfall and discharges alongside the grade.
Heacham was rated Sufficient for 2025, the minimum passing grade in the Bathing Water Regulations. That grade comes from bacterial samples taken over several seasons, so it describes the beach's record rather than the water on any given day.
The Environment Agency issues a pollution risk forecast each morning during the bathing season for nearly every bathing water in England, and the water company publishes the status of its storm overflows every few minutes.
The regulator records this as a bathing water whose quality can be affected by heavy rain, which is why rainfall in the last 24 hours is shown above.

Directions to this bathing water
That is the Environment Agency’s sampling point, which is at the water rather than at a car park. Your maps app will take you to the nearest road it can reach.
The nearest mapped car park is about 90m away in a straight line (Heacham North Beach Long Term Car Park). That is not a walking distance: OpenStreetMap knows where the car park is and nothing about the path, which may be longer, steeper or not there at all.
What is mapped at this beach
- Toilets about 100m away — free
- Drinking water about 90m away
- Silver Sands about 140m away
Straight-line distances from OpenStreetMap, not walking distances, and only what volunteers have mapped — something missing here may still be there.
What the regulator says about this beach
From the Environment Agency’s published bathing water profile for 2026. It describes the place and its catchment, not today’s water.
The beach itself
Heacham North Beach is part of an extensive beach line which stretches north from the mudflats at Snettisham, up the eastern side of the Wash and along the Norfolk coast. Heacham is a popular Norfolk coastal holiday resort, with a largely sandy beach. It is one of the few beaches in Norfolk to face west. The majority of beach exposed at low tide is very gently shelving. Tidal movement stirs up sand and sediment in the sea and makes it look cloudy.
What drains into it
The Heacham river and its tributaries flow through a largely rural catchment before passing through the urban area of Heacham. Here there are several holiday homes and caravan parks. Within the urban area there are a number of surface water drainage systems that enter the Heacham river. The river outflows to the sea 0.5km from the North beach. The Wash is the largest estuarine system in the UK. It is recognised as an internationally important site for waders and wildfowl under the Ramsar Convention, particularly in winter as well as during the spring and autumn migration, where it hosts hundreds of thousands of shorebirds. There is also a large population of gulls in the area, present all year round. The area is also a Site of Special Scientific Interest (SSSI), Special Area of Conservation (SAC) and a Special Protection Area (SPA).
More from the profile
Where the sewage works discharges
Heacham Sewage Treatment Works is located just south of Heacham (on Fenway) and discharges to a tributary of the Heacham river. Kings Lynn Sewage Treatment Works discharges to the Great Ouse estuary, approximately 14km southwest of Heacham. Improvements including UV disinfection were put in place at Heacham Sewage Treatment Works by Anglian Water in 1998. This has been effective in reducing bacteria numbers from the sewage works into the Heacham river system. Current data indicates that the UV treated effluent is present in some bathing water samples but is not contributing viable bacteria.
What has been done about it
Anglian Water have worked with the Environment Agency over a long period to help make improvements to their sewerage infrastructure in and around Heacham. Improvements have been carried out to local pumping stations, surface water outfalls and leaking sewers. This is intended to reduce water company impacts upon the Heacham River and Heacham bathing water. The Environment Agency will continue to work with Anglian Water to identify further areas for improvement to minimise the impacts of the sewerage infrastructure. Further investigations were undertaken by Anglian Water in 2021/2022 and the results showed the largest input of bacteria is from birds and secondly from the Heacham river.
What the samplers see on the sand
Environment Agency samplers make observations of litter present on the beach at every visit, this includes assessments of sewage debris, litter and tar. At Heacham for the four year (2022-2025) assessment period where data is available, sewage debris was not noted at this site. Litter was not assessed as being sufficient to be objectionable, but was observed as being present on 27% of visits. Tarry residue was not noted at this site.
The council's part
The Environment Agency continue to investigate surface water quality and identify any sources of reduced quality water which may affect the bathing water. Regular liaison meetings are held throughout the bathing water season between the Environment Agency, Local Authority, Anglian Water and other stakeholders to discuss ongoing work and actions.

If you get into trouble
This is the RNLI’s advice, not ours.
Float. Tilt your head back with your ears in the water. Relax and let your breathing settle. Move your hands and legs gently to stay level. Your legs may sink, and that is fine, everyone floats differently. The first shock of cold water passes in less than a minute, so do not try to swim straight away. Once it has passed, call for help or swim to safety.
Caught in a rip current? Do not swim against it, you will only tire yourself out. If you can stand, wade out of it. If the water is too deep to stand, swim parallel to the beach until you are clear of it, then head for shore. Raise your hand and shout for help.
Nobody publishes a rip current forecast for beaches in Britain or Ireland, so this site cannot show you one. The RNLI has one for its own lifeguards. The public does not. Look at the water before you get in, and look for a channel where the waves are not breaking.
In an emergency call 999 and ask for the Coastguard. In the Republic of Ireland call 112 or 999 and ask for the Coast Guard.
Where there are lifeguards, swim between the red and yellow flags. They put those flags where it is safest that day and move them as the sea changes. A red flag means do not go in, whatever this page says. An orange windsock means the wind is blowing offshore and inflatables should stay out of the water. Most places on this site have no lifeguard at all.
This advice is the RNLI’s. Their Float to Live pages are worth two minutes of anyone’s time.
