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.

March at Magheroarty delivers consistent but challenging surf conditions, with an average swell height of 2.2m and a solid 12.0s period, indicating powerful, well-spaced waves. The best swells arrive from the NW and WNW, making up the majority of rideable waves (6.55% and 6.13% respectively in the 1.5-2m range, scaling up to 7.32% for NW in 2-2.5m). These directions provide the cleanest and most sizable waves, though swells from the W and WSW also contribute, often with slightly choppier conditions. Wind is the limiting factor—only 14% of the time is it ideal (typically light offshore or cross-offshore from E/NE). However, prevailing winds are often from the SW to W (SSW-WSW directions account for the highest percentages in the 20-50kph range), which can create onshore chop, especially with stronger gusts. Larger swells (over 2.5m) are infrequent but possible (0.72-0.94% from NW/WNW), offering powerful surf for experienced riders. March requires patience for clean conditions, but when winds align, the spot handles the NW energy well, offering powerful, well-formed waves suited for advanced surfers who can navigate the occasional wind-affected peaks.
