The Lowdown
Alright folks, Rusty here with the long-range look at what's coming our way. Let's be straight with you: the next week is a bit of a write-off for Tullaghan (Leitrim) if you're looking for anything clean. The wind is just not playing ball with the swell for most of it, but there are a couple of windows of proper potential, especially late in the run.
We start off Tuesday the 15th and right through the middle of next week, it's messy. We've got a fresh to strong cross-onshore wind hammering a decent-sized, short-period swell. The wave energy is moderate to strong (302 to 4776), but the quality is poor. Thursday the 17th actually sees some serious size pushing in with a 9.8 ft to 11.5 ft swell from the west-northwest. The period is a long 13 seconds on that afternoon pulse, but with a strong 25 mph cross-onshore wind, the surface will be a mess. That's one for the tow-in crew or kites, not your standard paddle session.
Friday the 18th is the first glimmer of hope. The wind swings cross-off, and the swell, dropping from 8.2 ft down to 6.6 ft, is still packing a solid punch. It’s a clean wave with moderate energy (2190), but the surf is only marginal, likely due to tide issues. Keep an eye on that morning window. Saturday the 19th is back to the chop.
Now, Sunday the 20th is where things start to look interesting. We've got a 6.9 ft groundswell from the west-northwest, with a 12-second period bringing in moderate wave energy (1293). The wind is a light cross-off from the SSE, keeping it clean. This is a solid, rideable wave for the intermediate crew. It’s going to be worth a look, but it won't be the ultimate standout.
The real standout window comes on Monday the 23rd of September. This is the one to circle on the calendar. The morning delivers an excellent 8.2 ft swell from the west, with a very long 13-second period. The wave energy is strong (2376). The wind is a perfect light offshore from the ESE, which will groom the face beautifully. This is a proper groundswell, and that kind of period on a point break like Tullaghan will set up some long, lined-up walls. It's going to be a paddle-out, but the clean, powerful conditions are perfect for experienced surfers. The afternoon backs off a touch to 6.9 ft, but remains excellent, with a gentle cross-off breeze.
After that, Tuesday and Wednesday are average, but Friday the 26th sees a drop-off. The 27th and 28th are small and clean but barely surfable. The run then ends with a return of some clean, waist-high waves on the 29th and 30th, with a 3.9 ft swell and a 12-second period, which will be fine for logs and longboards.
Overall, bite through the slop this week. Sunday the 20th is your weekend fun, but Monday the 23rd is the standout. Set the alarm for that morning. The wind and the swell are finally going to click.
