The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Europe/London local. Folk tradition, not a scientific forecast.

Last spring tide on Sat 02 May (range 1.9m / 6.1ft). Next neap on Fri 08 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Great Yarmouth sits on a thin strip of sand between the North Sea to the east and the River Yare and Breydon Water to the west — a geography that has defined the town since its medieval herring-fishing peak. The North Sea here is mesotidal: mean spring range at Yarmouth runs around 1.8 to 2.0 metres, with neaps reducing to approximately 0.8 to 1.0 metres. Two tides a day, reliably semidiurnal, nothing dramatic in range — but on a low-lying coast where even a modest surge can push water onto the roads, that 2 metres matters more than it would on a cliffy coast with a similar range. The Yare mouth — Haven Bridge area — is where the tidal river meets the sea, and the interaction creates a daily pulse through Breydon Water, the broad tidal estuary that backs the town to the west. Breydon Water is a nationally designated SSSI: around 500 hectares of intertidal mudflat, saltmarsh fringe, and shallow open water that provides internationally important wintering habitat for white-fronted geese, pink-footed geese, golden plover, lapwing, and large numbers of ducks. The RSPB's Breydon Water reserve is accessed from the south bank. The best birding is on the falling tide when the mudflats begin to expose, pushing feeding waders and wildfowl into concentrated areas visible from the walkways. Tidal bores occasionally form in the River Yare on large spring tides when the flood pushes upstream with enough force to create a perceptible wave front. The bore is modest by global standards — nothing like the Severn or the Qiantang — but it is real, and anglers who fish the river upstream from the town are aware of it as a timing signal for the flood push. The salinity gradient in the river shifts with each tide: at high water springs the salt penetrates several kilometres upstream, pushing the freshwater fish species back and bringing in estuarine species that follow the salt front. Anglers fishing Breydon Water and the lower Yare target flounder, dace, roach, and occasional sea bass, with the tidal state governing where each species is likely to be feeding. The incoming flood two hours before high water is the consistent producer — fish moving onto the exposed edges as the water rises, actively feeding in the disturbance zone where fresh and salt water mix. On the sea beach, Great Yarmouth's wide North Sea strand runs several kilometres north from the harbour mouth. The beach widens at low tide as the sand exposed between the low and high water marks is considerable — with a 2 metre range on a gently shelving beach, the intertidal width can be 50 to 100 metres of firm sand above the low-water line. Families with children can plan for maximum sand exposure at low tide, while the beach at high water on a rough day is a narrower, more energetic place. The North Sea fetch from the northeast is long — the nearest coast in that direction is Denmark — and groundswells from North Sea storms can build to 3 to 4 metres offshore. The sandbanks off Yarmouth — the Nicholas, the Scroby, the Holm — absorb some of that energy, but the beach sees genuine surf on northeast winds. Scroby Sands Wind Farm sits on the offshore sandbank of that name, visible from the beach, and the commercial shipping lane through the channels between the banks makes the approaches to Yarmouth Harbour one of the more traffic-dense sections of the Norfolk coast. Navigation through the cross-channel approaches uses the tidal window in the harbour entrance channel, which can silt and shift. The coast immediately north of Yarmouth — Caister-on-Sea, California, Scratby — is a low-lying dune and clay cliff coast under active erosion. The combination of North Sea storm surge (the 1953 surge killed 307 people in East Anglia, still the UK's worst peacetime flooding disaster) and sea-level rise makes the coastal flood risk here genuinely serious. Spring high tides combined with northerly gale surge have inundated the roads behind Yarmouth in recent years; the Environment Agency's flood warning service monitors both tidal and surge conditions and issues advance warnings for the area. Any serious planning around this coast should check the EA flood alert system alongside the tide table. Predictions on this page come from Open-Meteo Marine, typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not a local gauge. On a 2 metre spring range, that height uncertainty of 0.2 to 0.3 metres is proportionally significant, so treat the times as planning guidance and use the authoritative Environment Agency gauge data for decisions where precision matters.
