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.

January at Magheroarty offers powerful winter surf conditions with an average swell height of 2.7m and a long 12.8s period, providing well-shaped, energy-packed waves. The dominant swell direction is from the NW-WNW sector (75% of waves over 1.5m), producing clean, organized lines when winds cooperate. However, onshore WSW-W winds occur frequently (30-40% of time), particularly at 20-50kph, which can deteriorate conditions despite the solid swell. Offshore or cross-offshore winds (ideal for surfing) occur only 10% of the time, mostly with NE-E winds. The largest waves (over 2.5m) come from NW-WNW directions but are relatively rare (2.5% of observations). Expect challenging paddle-outs due to the combination of powerful swells and strong winter winds, with the best windows occurring when NE winds align with NW swell directions. This is a spot for experienced surfers in January, requiring thick wetsuits and good wave selection skills due to the mixed wind/swell interplay.
