5.8 · Beach · Vale of Glamorgan
Cwm Colhuw Bay is a small, sheltered Vale of Glamorgan beach with mixed sand and scattered rock/weed patches, fished mainly by light surf tactics on the flooding tide. Access is on foot via paths and steps down to the bay, with fishing from the sand at low water and closer-in work around the rougher edges as the tide pushes in. Expect a relatively snag-light sandy bay for flatfish and school species, with occasional ray/dogfish and summer bass when there’s colour in the water.
Today · Best available
Best available: 18:00-21:00 around the rising tide
Most likely species: Plaice and Flounder
Poor conditions. Best available around 18:00-21:00 around the rising tide, but no window reaches the strong threshold today. Good chance of Plaice and Flounder.
Consider a backup mark if conditions do not improve.

Met Office · Open-Meteo
Where the data comes from. Weather and sea-state readings come from the Met Office and Open-Meteo forecast models, refreshed several times a day. High and low water are taken from tide-station predictions for this stretch of coast.
How the score works. Each window is scored 0–100 from the signals that most reliably move fish inshore: tide movement (a running tide carries food, so the last of the flood and first of the ebb are usually the prime spells), wind speed and direction (onshore wind stirs food into the surf — up to the point it makes fishing hard), sea state (a little wave and swell movement helps, heavy swell hurts), and weather — rain, temperature and light. Behind the headline number we score bite opportunity and comfort separately, and run a separate safety check on wind and swell. The size of the tide counts too: spring tides move more water than neaps, so the tidal range for this stretch of coast is weighed alongside the tide's direction, your target species and this mark — and unusually big springs strengthen the safety check, because the water rises faster and covers more ground.
Your target species counts. Pick a species below and the score also weights what we know about it — its season, preferred sea temperature, tide stage and sea state, and whether it feeds by day or night.
The rating is guidance, not a guarantee — conditions change fast on the coast, so always judge the sea in front of you before you fish.

Strong spring tides — the sea rises faster and reaches further up the shore than usual, so allow extra margin on access routes and cut-off points.
The fishing rating combines opportunity and comfort. Always check local sea conditions; the safety check is guidance, not a guarantee.
Spring vs neap tides. Spring tides have a larger difference between high and low water, so more water moves on each tide — usually stronger flow that stirs up food and gets fish feeding. Neap tides have a smaller range and generally gentler movement. The range here is compared with what is normal for this stretch of coast, and the cycle swings between springs and neaps roughly every week, following the moon.
Big spring tides: the water rises faster and covers more ground than usual — double-check access routes and cut-off points before you fish.

Cwm Colhuw Bay (often referred to locally as Cwm Col-Huw) is a small, scenic Vale of Glamorgan cove with mixed ground and classic south Wales surf/rock potential. It’s a handy “scratch” mark where you can pick up a variety of species if you fish it with the conditions rather than against them.
Cwm Colhuw Bay sits on the Vale of Glamorgan coast between the better-known bays and headlands, with access typically via local lanes and footpaths down into the cwm (valley) to the shore. The last part is usually on foot, and you should plan for a walk back up with kit.
This is a typical Vale mixed mark where you target seasonally, matching tactics to water clarity, surf, and tide. You’re most likely to encounter common inshore species, with occasional better fish when the sea has a bit of colour.
Cwm Colhuw suits straightforward surf tactics on the sand with a second option of light rock/kelp approaches if conditions allow. Keep rigs simple and robust, and let the sea state dictate whether you fish for bites (smaller hooks) or specimens (bigger baits).
This bay is at its best when there’s movement and a bit of “life” in the water—light surf, a touch of colour, and a steady tide. Very clear, flat conditions can make it hard work, particularly in daylight.
Cwm Colhuw is a beautiful but potentially serious venue—steep paths, slippery rock, and fast-changing conditions mean you should fish it with care. If you’re unsure, fish from the beach rather than exposed ledges.
Facilities are limited in and around small Vale coves, so arrive self-sufficient. Plan food, water, and tackle spares in advance.
This is a mark where small adjustments—where you stand, what you cast into, and how you present bait—make a big difference. Fish the features, not just the distance.
There’s no widely publicised, single blanket “no fishing” rule specific to Cwm Colhuw Bay that can be relied on without checking locally, but coastal access can be affected by private land, seasonal notices, or conservation measures. Always verify the current situation before fishing.
