Magheroarty - surf spot statistics

Best Surf Season (October - March)

The North Atlantic fires on all cylinders from October through March, delivering consistent, powerful swell to Magheroarty's NW-facing beach. Average wave heights hover between 2.6m and 3.6m with long periods often exceeding 12 seconds, thanks to a parade of intense extratropical cyclones rolling off the Labrador Sea. The downside? Onshore winds from the NW quadrant accompany many of these storms, limiting the 'clean' window. Still, when a high-pressure system parks over the British Isles, a crisp SE to S offshore flow transforms the beach into a world-class left point or beachbreak. These are the days you live for.

Fair Surf Season (April & September)

The transition months of April and September offer a compromise: solid swell (2.0-2.2m average) with a higher chance of favorable offshore winds (14-15% ideal). April sees the waning of winter's fury, but the N Atlantic still delivers regular WNW-NW pulses in the 10-14s range. September marks the ramp-up after summer, with the first major lows reawakening. Both months see a more balanced mix of swell directions, often with cleaner conditions as autumn lows stall south of Iceland.

Low Surf Season (May - August)

Summer arrives and the swell machine downshifts. Average heights drop to 1.5-1.8m and periods dip to 8-9s, typical of weaker, more distant swell sources. The dominant W and NW swell still reaches the coast, but you'll be hunting for sandbars to make the most of fun-sized, rippable waves. The silver lining: offshore wind frequency increases to 15-16%, offering plenty of groomed, glassy mornings. It's a great time for longboarding and fine-tuning your rail game, but don't expect to get pitted.

January: The Deep Freeze of Power

The North Atlantic is in full winter mode, generating raw, long-period swell that pummels the coast. With average heights of 3.6m and periods around 12.5s, Magheroarty sees consistent XXL sized waves from the W and WNW – exactly the directions that wrap into its NW-facing sandbars. However, the same low-pressure systems that produce these swells often bring strong onshore winds from the NW-N quadrant (combined ~9.6%), making it a challenge to find clean conditions. Only about 8% of the time does the wind align from the S-SSW, creating glassy offshore corridors. When it does, expect heavy, grinding barrels with plenty of juice for charging. The NAO typically sits positive, keeping the storm track aimed at the UK, so patience is key.
