Magheroarty - surf spot statistics

Magheroarty in Ireland is a swell-rich spot with consistent waves for much of the year, though the best conditions for surfers are typically found during the autumn, winter, and early spring months. The highest-quality waves occur from October through March, when ground swells dominate (59-88% frequency) and mean swell sizes range from 1.9m to 2.7m. These months offer powerful, clean waves, particularly in January and February when ground swells reach 88%, and swell heights average 2.6-2.7m. However, wind conditions are often challenging, with bad onshore winds occurring 86-90% of the time in these peak swell months, meaning surfers must time their sessions carefully around wind shifts. From April to September, the swell mix shifts toward wind swells (56-78% frequency), resulting in smaller, less consistent waves (1.2-1.6m). While summer months like June and July see poor ground swell contributions (15-27%), they do offer slightly better wind conditions (19-21% good winds) compared to winter. However, the waves are generally weaker and less ideal for advanced surfers. For the best balance of solid swell and manageable winds, late autumn (October-November) can be a strong choice, as ground swell remains dominant (59-73%) with slightly lower wind interference than mid-winter. Ultimately, committed surfers will prioritize winter months for larger, cleaner waves despite frequent onshore winds, while summer may appeal to beginners or those looking for more relaxed conditions.

December at Magheroarty offers solid surf conditions with a dominant NW swell direction, delivering consistent waves averaging 2.4m in height and a powerful 12.4s period. The majority of waves fall in the 1.5–2.5m range, with larger sets exceeding 2.5m occurring 16% of the time—ideal for experienced surfers. Swells from the NW and WNW contribute most frequently, providing well-organized, clean waves when paired with favorable winds. However, onshore winds are common, with only 11% of days offering ideal wind conditions (light offshore or cross-offshore). Strong SW to W winds (20–50+ kph) prevail, often creating choppy or blown-out surf, particularly during energetic low-pressure systems. Winter storms can bring powerful but messy conditions, while cleaner sessions are rarer and often coincide with high-pressure setups. Timing is key—watch for wind shifts and swell windows around NW angles for the best rides. Cold water and challenging weather demand proper preparation, but those willing to brave the elements will find rewarding, powerful waves.
