6.6 · Harbour · Isle of Anglesey
Bull Bay (Porth Llechog) is a small, open cove on Anglesey’s north coast where most shore fishing is from the harbour walls and rough rocky ground either side. Access is straightforward via the village/harbour with short walks to marks, and fishing is typically mixed—float/spin for wrasse and pollack in daylight, with bait fishing into deeper water for dogfish, conger and the occasional ray, especially on bigger tides.
Today · Best available
Best available: 18:00-21:00 around the falling tide
Most likely species: Ballan Wrasse and Pollack
Fair conditions. Best available around 18:00-21:00 around the falling tide, but no window reaches the strong threshold today. Good chance of Ballan Wrasse and Pollack.
Fishable, but pick your timing carefully.

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.

Bull Bay (Porth Llechog) on Anglesey’s north coast is a sheltered, deep-water bay with rocky headlands that can fish well in a wide range of conditions. It’s a popular spot for both bait and lure anglers, with the best sport usually coming from the rougher ground on the edges rather than the sandy middle.
Bull Bay sits at the northern end of Anglesey, with access via the village and harbour area at Porth Llechog. Most anglers fish either from the harbour/sea wall area or by walking onto rock ledges around the bay when the sea state allows.
Bull Bay offers a classic north-Anglesey mix, with the bay and harbour producing smaller species and the rougher edges holding better predators. Species can vary a lot with season, water clarity and surf conditions.
This is a versatile mark where you can match the method to conditions—cleaner water suits lures and floats, while a bit of colour favours bait on the deck. The key is to fish the transitions: sand-to-rock, kelp edges, and any gullies.
Bull Bay can fish across most states of tide, but the most productive periods usually revolve around movement and a bit of natural disturbance. Water clarity can change quickly, and that often dictates whether bait or lures will dominate.
The harbour and promenade-style areas are comparatively straightforward, but the surrounding rock marks demand proper judgement. Anglesey rock can be extremely slippery, and Bull Bay’s exposure to swell means conditions can change fast.
As a village bay and small harbour, Bull Bay is more comfortable than many remote Anglesey marks. You can usually find basic amenities nearby, especially in peak season.
Bull Bay rewards anglers who keep moving and fish the features rather than blindly casting into the middle. If you treat it as a set of small marks—harbour, bay, and rocky edges—you’ll quickly work out where the fish are holding.
Sea angling is generally permitted around much of Anglesey, but local restrictions can apply around harbours, slipways, and specific safety zones. I’m not aware of a blanket ban at Bull Bay itself, but you should treat signage and harbour byelaws as the final word.
