Cemaes Bay

Cemaes Bay is a friendly, easily accessed north-coast Anglesey mark that can fish well for classic mixed-bag species, especially when there’s a bit of colour in the water and some tide movement. It’s not a single “spot” so much as a collection of options—harbour walls, sandy bay, and nearby rocky ground—so you can tailor tactics to conditions.

• A versatile venue: float fishing, light ledgering, and lure fishing can all be productive here
• Best regarded as a “species and sport” mark rather than a guaranteed big-fish venue (though good fish do turn up)
• Sheltered compared with fully open-coast marks, but still very tidal and exposed in certain winds
• Excellent for beginners/intermediates because you can find fishable water in many conditions

Cemaes Bay sits on the north coast of Anglesey with access from the village down to the harbour and beach. You can generally reach the main fishing areas on foot via paved paths and slipways, but conditions and harbour activity dictate where it’s sensible to fish.

• Access is typically from the harbour area, promenade/paths, and the beach itself depending on the state of the tide
• Harbour walls and nearby rocks offer deeper water than the open sand, especially on bigger tides
• After storms, the bay can hold coloured water that brings fish close, but some routes may be slippery or wave-washed
• Be considerate around boat movements, moorings, and working areas—choose positions that don’t obstruct harbour users

Cemaes Bay can produce a useful range of north Wales staples, with a mix of sand, weed, and rock influencing what turns up. Expect the “regulars” to dominate, with seasonal visitors appearing when water temperatures rise.

• Bass: possible around rougher water and harbour/rock edges, especially on dawn/dusk tides and after a bit of swell
• Mackerel: summer runs can be good from harbour walls/rocky points when fish are close
• Pollack & wrasse: more likely where there’s kelp-covered rock and depth; often better on float tactics
• Flounder & dabs: common over sand, especially with worm baits and smaller hooks
• Dogfish, whiting, and coalfish: may show depending on season and water clarity
• Crab and occasional lobster presence indicates good rough ground nearby—use it as a clue for wrasse/pollack territory

You can fish Cemaes Bay effectively with fairly light gear if you adapt to tide strength and snags. The key is matching your approach to the ground: clean sand allows simple rigs, while rough/weed calls for stronger traces and snag-aware tactics.

• Beach/sand ledgering: simple running ledger or 2-hook flapper with worm baits for flatfish and general species
• Rough-ground ledgering: short snoods, abrasion-resistant leader, and a slightly heavier lead to hold bottom near rocks
• Float fishing: a very effective way to pick up pollack/wrasse along kelp edges—fish close in and keep moving until you find feeding fish
• Lure fishing: small soft plastics, metals, or plugs for bass/mackerel/coalfish—work edges of current and any surface activity
• Common baits: lug/ragworm for general fish and flatfish; mackerel strip/sandeel-style baits for predators; peeler/crab can be excellent where wrasse and bass are present
• Practical tip: carry a range of lead sizes—tide and swell can vary quickly even within the bay

Cemaes is strongly influenced by Anglesey’s tidal streams; even in a bay, current can push hard around harbour mouths and points. It often fishes best when there’s movement without excessive weed, and when wind/swell create a little colour.

• Best tide stages: typically the middle hours of the flood and ebb when fish feed confidently and you can hold bottom (varies by exact position)
• Water clarity: slight colour after a blow can improve bass and general fishing; very clear, calm conditions can make fish cautious in daylight
• Swell/weed: kelp and loose weed can be a nuisance after rough weather—adjust by shortening snoods and checking baits frequently
• Wind direction matters: onshore winds can stir the bay (sometimes good for bass) but can also make harbour walls and rocks unsafe
• Night vs day: dusk and darkness can bring bass and better-quality fish closer; daylight is often good for mackerel and float species

This is a generally accessible venue, but it still demands proper sea-angling caution—slippery rock, sudden waves, and strong current can turn a comfortable session into a risky one. Choose stable platforms, keep an escape route, and don’t fish the rougher edges in heavy swell.

• Slips and algae: harbour walls, steps, and rock ledges can be extremely slippery—wear proper footwear and move slowly
• Wave action: avoid low ledges and the seaward faces in swell; rogue waves can wash platforms without warning
• Tidal cut-off: some rocky areas can cut you off on a rising tide—plan your route and watch the waterline
• Lines and moorings: be careful casting near boats, ropes, and harbour infrastructure
• Family-friendly areas: the beach and more sheltered harbour-side spots can be suitable with supervision, but keep children well back from edges
• Weather check: north-coast winds can strengthen quickly—if in doubt, fish more sheltered water or pick another mark

Cemaes is convenient by Anglesey standards with village amenities close to the water. That makes it a comfortable choice for short sessions, evening trips, and anglers who want easy access to supplies.

• Nearby village services (shops/food) are typically within easy reach from the harbour area
• Parking is generally available in the village/near the waterfront, but availability can vary at busy times
• Shelter: you can often find some cover depending on wind direction by choosing positions around the bay/harbour
• Tackle/bait: availability can be variable locally—bring key baits/tackle if you’re travelling, or check nearby suppliers in advance

Think of Cemaes as a “move-and-search” mark: try a method for 20–30 minutes, then adjust distance, depth, and position until you contact fish. Small changes—like fishing closer to structure or stepping into slightly deeper water—often make the difference here.

• For mackerel: look for birds, surface flashes, or baitfish; a short-range feathering session can outfish long casts when shoals are tight in
• For bass: fish the edges of tide flow and any rougher, coloured water; dawn/dusk and after a bit of swell are prime windows
• For wrasse/pollack: float a bait tight to kelp edges and be ready to steer fish clear of snags immediately
• On sand: scale hooks and baits to what’s present—smaller, well-presented worm baits often beat big cocktails in calm conditions
• Keep gear flexible: a light lure rod plus a small ledger setup covers most opportunities without overcomplicating the session

There may be local rules affecting where and how you can fish around the harbour, including safety exclusions, working areas, and temporary restrictions. I’m not aware of a clear blanket ban that applies to all of Cemaes Bay, but you should treat harbour signage and local instructions as definitive.

• Check on-site harbour notices/signs for any “no fishing” sections, access limitations, or rules around pontoons, moorings, and slipways
• Be mindful of other restrictions that can apply in Welsh coastal waters (e.g., bylaws, conservation measures, and bass-related rules) and confirm current requirements via official sources
• If collecting bait (worms, shellfish, crabs), check local rules and landowner/foreshore permissions—don’t assume it’s automatically allowed
• Respect other water users and avoid obstructing navigation; if challenged by harbour staff, comply and relocate
