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 45 per 100ml, on 21 September 2023; 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.
Selsey 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.
The nearest mapped car park is about 390m away in a straight line (East Beach). 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
- Toilets about 480m away
- East Beach Kiosk about 470m 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 Drift Road (adj), East Beach Road, about 30m 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.
The record since 2021
In 2025, the 3 monitored overflows the Environment Agency lists against this bathing water spilled 9 times, for about 62 hours in total. Over the 2025 bathing season alone, 1 May to 30 September, 2 of those spills happened — 22% of the year. One of the monitors behind that figure was working for 68% of the season, so the real count may be higher.
- 20211 spill · 1 hours
- 20221 spill · 4 hours
- 20231 spill · 0 hours
- 202427 spills · 174 hours
- 20259 spills · 62 hours
These are annual totals for the whole year, not readings from today — today’s answer is the verdict at the top of the page. Figures come from the Environment Agency’s Event Duration Monitoring annual returns, which the water companies submit and the EA publishes, and the EA decides which overflows count as belonging to this bathing water.
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
The bathing water is situated on the south coast between Pagham Harbour and Selsey Bill in West Sussex. The bathing water faces southeast and is primarily a groyned, shingle beach but with some sand exposed at low water. To the north of the bathing water there are underwater rock formations which are exposed at low water. A promenade sits above much of the beach with the town of Selsey immediately to the south.
What drains into it
The bathing water is situated in the south of a low lying area known as the Manhood Peninsula. The natural drainage (hydrological) catchment surrounding the bathing water is approximately 170 hectares. Two km to the north is Pagham Harbour and most drainage in the surrounding area enters the harbour via Broad Rife. The adjacent town of Selsey is immediately to the south and the surrounding area is predominantly arable or managed grassland.
More from the profile
Where the sewage works discharges
Pagham sewage treatment works and Sidlesham sewage treatment works discharge treated effluent into Pagham Harbour via Pagham Rife and Broad Rife respectively. Both are 5 km from the bathing water and these discharges are designed to present minimal risk to water quality.
What has been done about it
Prior to 2001, treated sewage was discharged from Bognor long sea outfall (6 km from the bathing water). In 2001, flows from Bognor Long Sea Outfall were diverted to a new sewage treatment works at Ford for further treatment and then discharged out of Littlehampton Long Sea Outfall (18km from the bathing water). The Bognor outfall was retained solely for storm discharges. As part of Southern Water’s Bathing Water Enhancement Programme (from 2016 to 2019), Southern Water have worked with partners and delivered solutions to improve bathing water quality.
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 Selsey 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 22% 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.
