Conditions at Dunmoran Strand in January
January: Deep-Winter Power
January is the statistical peak of the North Atlantic storm year at Dunmoran Strand. Average swell height comes in around 9ft (2.7m), and average wave period stretches to 12.5s, which puts the surf squarely in the powerful, long-period category. The swell rose is stacked with W (13.9%) and WNW (11.9%) energy, while NW and NNW together add another 13.6%; the NNW component is especially valuable because it lines up almost directly with the beach's north-northeast exposure. Westerly groundswell wraps in behind the headlands and still brings significant size. Only 25% of the time is the wind blowing from the offshore SSE/S/SSW/SW quadrant, however, and when lows fire the onshore N/NNE/NE/NNW flow turns the same energy into lumpy, closed-out surf. Water temperature is 9.2°C, air temps hover around 7°C, and rain is frequent. This is heavy, charging territory - pick the clean post-frontal days and you'll be rewarded with some of the biggest, most powerful waves of the year.
