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 82 per 100ml, on 18 September 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.
Every one of these counts is far below the standard for Excellent, which is why the bars sit low in the box: the gap above them is how far this water is from the line, and a flat row here is the good outcome. 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.
Sandymouth 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.

Lifeguards
The RNLI has a lifeguard unit at this beach.
They do not patrol all year, and this page cannot tell you whether anyone is on duty today. RNLI page for this beach.
Where it is, and what discharges near it
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 290m away in a straight line (Sandy Mouth Carpark). 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. It is tagged as charging a fee, as the mappers wrote it.
What is mapped at this beach

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
Sandymouth is on the north coast of Cornwall. It is a sandy beach, approximately one kilometre wide, backed by pebbles and cliffs. There are also rock pools and waterfalls from small streams that flow to the beach.
What drains into it
The catchment surrounding Sandymouth is approximately 120 hectares. The Sandy Mouth Stream is 1.25km long and enters the sea at the bathing water. There is also a smaller stream approximately 0.75km long that enters the sea at Sandymouth beach. The steep catchment means rain runs off rapidly into the stream. Land use is rural with just one or two farms.
More from the profile
Where the sewage works discharges
The outfall from Bude STW discharges into the sea off Compass Point approximately 3.8km south of Sandymouth bathing water. This discharge is designed to protect bathing water quality.
What has been done about it
In the past sewage at Bude was discharged without treatment through a short outfall off Compass Point. The South West Water sewage treatment scheme for Bude, which provides primary treatment and a one kilometre long sea outfall, was completed in 1993. The Bude sewage treatment works (STW) was upgraded with secondary treatment by the end of 2000. Improvements to the combined storm overflow (CSO) at Stratton pumping station were also completed at that time. In recent years the Environment Agency has worked extensively with South West Water to identify and rectify issues with bacterial contamination of the River Strat from degraded sewers in Bude. Storm overflow event duration monitoring (EDM) was installed at Crooklets Car Park by December 2011 and a sewage leak to Flex Brook was fixed. Storm overflow event duration monitoring (EDM) was installed at The Strand, Nanny Moores, Summerleaze Car Park, and at the Stratton and Castle pumping stations by April 2011. EDM was installed at the Barn Orchard Cottages pumping station in March 2016. EDM is to be installed at Broadclose Farm CSO by September 2021. Improvements to 7 emergency/storm overflows within the nearby Crooklets and Summerleaze bathing water catchments are due for completion by September 2022.
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 Sandymouth for the four year (2022-2025) assessment period where data is available, sewage debris was not noted at this site. Litter was assessed as being sufficient to be objectionable for 1% of visits, with 34% of visits noting the presence of litter. Tarry residue was not noted at this site.
The council's part
The Environment Agency have regularly inspected and sampled surface water outfalls.

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.
