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, 2023 to 2026
45 samples, 2023 to 2026. The highest E. coli count in them was 280 per 100ml, on 26 August 2025; 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.
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.
Christchurch Mudeford Sandbank East was rated Excellent for 2025, the highest of the four grades 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.

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.
No car park is mapped within 800m of here in OpenStreetMap. That is a gap in the map as much as it is a fact about the place.
What is mapped at this beach
- Toilets about 50m away — free, step-free, baby change
- Drinking water about 400m away
- Beach House Café Restaurant about 110m away
Straight-line distances from OpenStreetMap, not walking distances, and only what volunteers have mapped — something missing here may still be there.
Getting here without a car
- Nearest bus stop Hengistbury Head Beach (S-bound), about 210m away
- Nearest railway station Christchurch Rail Station, 3.6 km away
Straight-line distances to where the stop or station is, from the national registers of them. That a stop exists is not a promise that a bus calls at it — timetables are somebody else’s data and this page does not read them, so check the operator before you rely on it.
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
Christchurch Mudeford Sandbank is in Christchurch Bay on the Dorset coast. The bay is approximately 13 kilometres wide from Hengitsbury Head to Hurst Castle. Mudeford Sandbank is a sandbank beach resort, approximately one and a half kilometres wide, with views across the harbour.
What drains into it
The catchment surrounding Christchurch Mudeford Sandbank East is approximately 300,000 hectares and includes the Hampshire Avon and the River Stour. The Avon is approximately 95km long and rises in Wiltshire in the Vale of Pewsey. It then flows south across Salisbury Plain through Durrington, Amesbury and Salisbury where all the significant tributaries of the Avon come together, including the Nadder, Wylye, Bourne and Ebble. The upper Avon catchment includes the undulating, chalk downlands of Salisbury Plain, which are cut by steep combes and river valleys. The steep catchment means rain runs off rapidly into the river. To the south of Salisbury the Avon enters the rolling farmland of the Hampshire Basin, flowing along the western edge of the New Forest through Fordingbridge and Ringwood. The Avon meets the River Stour at Christchurch and flows into Christchurch Harbour and the English Channel at Mudeford. The River Stour is approximately 96km long and flows east from Stourhead in Wiltshire through the Blackmore Vale and the towns of Gillingham and Sturminster Newton, where it is joined by the River Lydden. The river breaks through the chalk ridge of the Dorset Downs at Blandford Forum, and flows southeast into the heathlands of south east Dorset. At Wimborne Minster it is joined by the River Allen, and meets the River Avon at Christchurch. Outside the urban areas of Bournemouth, Poole and Christchurch, the catchment is mainly agricultural with more than 50 farms.
More from the profile
Where the sewage works discharges
All the significant sewage treatment works in the lower catchment receive UV disinfection, and further up the catchment there are smaller, treated, continuous discharges. These discharges are designed to protect bathing water quality.
What has been done about it
Wessex Water made improvements in 1994 to reduce the frequency of emergency overflows from two combined sewer overflows (CSO) which discharge to the River Stour. Improvements to the treatment capacity and storm storage at Holdenhurst Sewage Treatment Works (STW) were also completed at that time. Ultraviolet (UV) disinfection was provided at Christchurch STW by May1998 and by April 2001, UV treatment and additional storm storage was installed at Holdenhurst STW. Improvements to an emergency overflow from a pumping stations at Iford were completed in 2002. The storm discharge from Christchurch STW was improved by April 2003, and the STWs at Wimborne, Kinson, and Palmersford received UV disinfection by the end of 2003. The CSO at Tuckton High Street was rebuilt and made larger by April 2004 and the storm discharge from Kinson STW was improved by April 2005.
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 Christchurch Mudeford Sandbank East 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 60% of visits. Tarry residue was not noted at this site.

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.
