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.

September at this surf spot offers moderately consistent conditions with an average swell height of 1.6m and a solid period of 10.4s, indicating well-formed, rideable waves. The primary swell directions are from the W, WNW, and NW, delivering the most frequent and sizable waves—particularly in the 1-2.5m range. WSW and NW swells also contribute, though with slightly less consistency. Wind conditions are favorable only 18% of the time, with the best chances likely occurring during lighter offshore or cross-shore winds from the E to NE. However, prevailing winds are often from the SW to W, which can create choppy or onshore conditions, especially at higher speeds (20-40kph). Expect a mix of smaller, clean days and larger, wind-affected sessions, with the occasional overhead+ swell (2.5m+) from the W or NW. Intermediate to advanced surfers will find the most opportunities, though patience may be required for ideal windows.
