Doughmore - surf spot statistics

Best Surf Season (October - March)

The North Atlantic roars to life as autumn deepens, and Doughmore transforms into a powerful, consistent surf destination. From October through March, the region is repeatedly hammered by deep extratropical cyclones tracking across the Atlantic, generating long-period, heavy swell that slams into this west-facing beach. The average wave heights hover between 1.8m and 2.5m, with periods routinely in the 11-13 second range, meaning the waves arrive with serious, groundswell energy. The dominant swell directions — W, WSW, and WNW — align perfectly with the beach's optimal swell window, while the wind regime offers a decent 22-26% chance of offshore easterly winds. When a strong high-pressure system settles over Scandinavia, it funnels cold, dry NE-ENE winds straight into the bay, creating clean, lined-up waves that are both powerful and rippable. This is the peak season for Doughmore, delivering the goods for intermediate to advanced surfers.

Fair Surf Season (April - June)

As the North Atlantic storm track begins to weaken and shift north, the months of April, May, and June bring more variable conditions. The average swell height drops to 1.1-1.4m, and wave periods settle into the 9-11 second range — solid, punchy, but less horsepower than winter. Offshore wind frequencies peak during this period, especially in April when ideal wind conditions occur 31% of the time, often associated with a building Azores high. The swell direction remains heavily weighted toward W, WSW, and WNW, so Doughmore still picks up plenty of energy, though the waves become smaller and more forgiving. This is a fantastic time for progressing surfers, with fun, rippable waves on the best days, but also a fair share of small, groveling conditions when the swell is under 1m.

Low Surf Season (July - September)

Summer months at Doughmore are the most challenging for quality surf. The North Atlantic high-pressure ridge dominates, squashing storm development and limiting swell generation to distant, weaker fronts. Average swell heights bottom out at 1.1m in July and August, with periods dipping to 8-9 seconds — making for short-period, wind-swell-driven waves that lack power and organisation. The wind statistics are particularly cruel: the ideal offshore wind frequency falls to just 18% in July and August, while prevailing southwesterly winds create choppy, onshore conditions more often than not. September shows a promising uptick again as the first autumn storms begin to form, with average heights climbing to 1.5m and periods to 10s, but it remains a transitional month. Surfers should not expect much here during the core summer, but the occasional late-summer Atlantic storm can still deliver a glassy, fun-sized day.

September: Autumn Ignition

September is the pivotal month when Doughmore wakes up from the summer doldrums. The average swell height climbs to 1.5m and the period increases to 10.2s, signalling the return of genuine groundswell energy. Swell direction is again dominated by W (37.0%), WNW (21.9%), and WSW (17.1%), with a notable increase in waves over 1.5m. The wind improves too, with ideal conditions 24% of the time, often from NE or E as early autumn highs form. This combination produces more frequent clean, round waves in the FUN to SOLID range. September is a transition month — not yet consistent, but the quality is markedly better than summer. For surfers, this is the time to start watching the Atlantic forecast closely, as the first major swell of the season often arrives in late September.
