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.

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.

2021Excellent
2022Excellent
2023Excellent
2024Excellent
2025Excellent

Every sample, 2022 to 2026

45 samples, 2022 to 2026. The highest E. coli count in them was 520 per 100ml, on 26 August 2022; 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.

Good standard, 500
Excellent, 250

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.

Southwick 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

Map loads as you scroll here

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 110m away in a straight line. 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 40m away — free
  • Carats Cafe Bar about 30m 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 Shoreham Port (adj), Albion Street A259, about 300m away
  • Nearest railway station Southwick Rail Station, about 420m 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 5 monitored overflows the Environment Agency lists against this bathing water spilled 47 times, for about 112 hours in total. Over the 2025 bathing season alone, 1 May to 30 September, 19 of those spills happened — 40% of the year. One of the monitors behind that figure was working for 77% of the season, so the real count may be higher.

  • 20218 spills · 8 hours
  • 202252 spills · 111 hours
  • 202357 spills · 216 hours
  • 2024147 spills · 1,600 hours
  • 202547 spills · 112 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 in West Sussex, adjacent to Shoreham Harbour. The beach is on a thin peninsula of land with the harbour behind. The bathing water is predominantly a groyned, shingle beach but with some sand exposed at low water. The River Adur exits the harbour at the western end of the bathing water separated by a concrete breakwater.

What drains into it

The bathing water is situated at a low lying peninsula of land at the entrance to Shoreham Harbour. The natural drainage (hydrological) catchment surrounding the bathing water is approximately 45,000 hectares. This includes the catchment of the River Adur which enters the sea at the western end of the bathing water. The local area behind the bathing water is urban but most of the wider surrounding area is predominantly rural (arable and managed grassland).

More from the profile

Where the sewage works discharges

There is a high standard of treatment at the two sewage treatment works discharges 3.2 km and 9 km from the shore of this bathing water which are designed to protect bathing water quality.

What has been done about it

Prior to 2002, treated sewage was discharged from Shoreham and Worthing Long Sea Outfalls (3.2 km and 9 km from the bathing water respectively). In 2002, Shoreham and East Worthing sewage works were upgraded and the effluent is treated before being discharged through the long sea outfalls.

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 Southwick for the four year (2022-2025) assessment period where data is available, sewage debris was not assessed as being sufficient to be objectionable, but was observed as being present on 3% of visits. Litter was assessed as being sufficient to be objectionable for 5% of visits, with 53% of visits noting the presence of litter. 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.
