The best season on the Wicklow coast
Updated for the 2026 season. Late May opens the main summer window on the Wicklow coast, with mackerel, wrasse and pollack already fishing well and bass and smoothhound stepping up through June. From late May to August this is the most productive stretch of the year: water temperatures climb, migratory species push inshore, and long evenings let you fish the full tidal cycle. This guide covers species, marks and tactics for June, July and August.
The Irish Sea warms slowly, you rarely see the full summer arrivals before late May, but once sea temperatures stabilise above 13°C the fishing transforms. Bass move into beaches and estuaries to feed on sandeel, crab and small flatfish. Smoothhound arrive in numbers from June. Mackerel flood into every harbour and headland. Wrasse and pollack are at peak weight from rock marks. And the long daylight hours mean you can fish the magical last hour of light without staying up until midnight.
Species and when to target them
Bass
May to SeptemberThe summer target. Bass are established on beaches from June when water hits 14°C. Brittas Bay, Greystones South Beach, Jack's Hole and Kilcoole are the best marks. Surface lures at dawn in flat-calm conditions, soft plastics through the day, peeler crab on a running ledger at dusk for the bigger fish that move close in low light.
Smoothhound
June to AugustThe most reliable summer species from Wicklow beaches. Arrive in earnest from early June, peak in July. Brittas Bay, Kilcoole and beaches south of Wicklow Town all produce fish. Fresh peeler crab on a running ledger at 50 to 80m: on open sand at Brittas Bay a flooding spring tide is the classic; on the Greystones to Wicklow shingle belt (Kilcoole, Greystones South, Murrough, Silver Strand) many sessions fish better on the ebb after an easterly colours the water, check the spot guide for the mark you are on. Fish of 5 to 10kg are possible, they fight hard and run fast.
Mackerel
May to SeptemberThe most abundant summer species, every pier and headland holds mackerel through the summer months. Greystones Harbour and Wicklow Town Pier are most consistent. Feathers and small metal lures cast and retrieved at any depth. Outstanding eating fresh on the day.
Wrasse and pollack
April to October, peak summerBoth peak through summer. Ballan wrasse reach best weights in June and July when water is warm and they feed aggressively in the kelp beds. Wicklow Head is the standout venue, rough ground below the lighthouse holds good wrasse and pollack to 3kg. Float-fished ragworm for wrasse, white rubber eels for pollack in the evening.
Dogfish
Year round, active summer nightsPresent on most beaches from spring through autumn. On summer nights they provide near-guaranteed action when waiting for bass or smoothhound. Mackerel strip on a simple running ledger works well.
Month by month
June
ExcellentThe season properly opens. Smoothhound and mackerel arrive, bass are established on beaches, wrasse are at their best. Long days mean you can fish the evening tide (ebb-weighted on north Wicklow shingle; flood-to-high still strong on open sand like Brittas) and walk back in daylight. Peeler crab comes into its own, shore crabs are moulting through June and self-collected peeler is lethal bait.
July
OutstandingPeak summer. Water temperatures at their highest. Mackerel in every harbour. Bass active through the day on lures and into the night on bait. Surface lure fishing is at its best in July, flat-calm dawns and evening sessions when the sea lies off produce the visual takes that define summer shore fishing. Garfish appear at harbour walls on light tackle.
August
GoodAugust is the last month of reliable summer conditions. Smoothhound start to thin out by late August as water cools. Bass remain present and actually improve as the season turns towards autumn, bigger fish push into marks in September. First flounder of autumn appear in the second half of August. Take August seriously, it is the last reliable warm-water window before the autumn species take over.
Tides and timing
Tide choice in summer follows the ground. On open sand (Brittas Bay and similar), fish often move in with the flood, the last two hours of flood through the first hour of ebb is a reliable window. On the Greystones to Wicklow shingle belt, regional write-ups lean toward the falling tide for bass and flatfish after a blow. A practical rule: arrive in time for the stage of tide your spot guide recommends, fish through high water when it matters for that mark, and stay for the first hour of ebb where that still overlaps the bite. Fading light on a calm evening stacks the odds on any of these patterns.
Summer safety note
Swell warning
Calm summer days lull anglers into a false sense of security on rock marks. Ground swells from distant Atlantic storms can arrive on a flat-calm day and wash rock marks that look perfectly safe. Always check the swell forecast before fishing any elevated rock mark, not just the wind. Wicklow Head in particular can take a south-easterly swell that doesn't show in local wind conditions.
