Rossbeigh Strand Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it for Rossbeigh Strand.

Right off the bat, I’ve got to be honest with you – this outlook is a bit of a story of waiting for the good stuff. The first week is pretty much a write-off. We’ve got sizeable swell hitting the coast, but it’s coming in with a nasty cross-onshore wind that’s just trashing the surface. The water is a touch warmer than normal for this time of year, sitting at 62°, but that’s about the only thing that’s friendly.

Monday the 7th and Tuesday the 8th are a mess. We’re looking at 10ft of swell from the WSW and WNW, but the wind is a fresh 16 mph cross-on. The wave energy is strong – in the 1400 to 2166 range – but it’s all just lumpy, choppy, and hopeless. Don’t bother paddling out. This is more of a kite-surfing setup if anything.

Wednesday the 9th sees the swell drop to 5ft, but it’s still a cross-on breeze and the period is a weak 8 to 9 seconds. The energy drops way down to 229-398, and the notes say it’s marginal at best. Thursday the 10th brings a pulse back up to 8ft from the WSW with a 10-second period, and the wind goes cross-shore, but the energy is moderate (1175) and the conditions are still just “slightly choppy.” It’s not garbage, but it’s not worth getting excited about.

Friday the 11th is the first real glimmer. We’ve got a morning session with 4ft from the WNW and a clean offshore wind from the WNW. That’s a major positive. The energy is weak (385), but with glassy conditions, these waves will be clean. It’s a beginner-friendly height, but it’s a beach break, so the short period (8 seconds) won’t be doing it any favors. Still, that’s your best bet for the whole first week. Saturday the 12th offers a bit more size, 7ft, and a long 13-second period, but the wind is questionable, and the energy is high (1925). It’s a gamble.

We then hit a dry patch from the 13th through the 17th. The swell is small, the wind is mostly onshore or cross-onshore, and the energy is pathetic. The 17th has practically nothing – 1ft swells. It’s a proper flat spell.

Now, here’s where it gets interesting. The real standout is Friday the 18th of September. The morning session is looking promising. We’re expecting 4ft of swell from the WNW with a clean 10-second period, but the wind is coming from the SSE at only 3 mph, which is a cross-offshore breeze. The forecast says “expect good surf conditions” and the energy is a moderate 356. The surface will be clean. For a beginner spot like Rossbeigh, that’s about as good as it gets. The crowds here are *sometimes* an issue, but on a Friday morning with that kind of forecast? You might actually have a few waves to yourself.

After that, the weekend of the 19th and 20th gets messy again. Saturday the 19th is a washout, but Sunday the 20th brings a massive 10ft groundswell from the W and WNW with a long 11-second period. The wind is offshore, and the energy is very strong (1840-1993). This is an expert-only day. The waves will be powerful and that long period means the beach break might be a bit of a closeout, but for the right crew, it’s game on. It’s a long-range call, so keep an eye on it.

The final few days of the 22nd are another big pulse of 10ft, but the wind is howling onshore again. It’s a no-go.

So, to wrap it up: the first week is a no. The 11th is your only chance for a clean, small wave. The real winner is the 18th of September – that’s the date to circle. The 20th is for the big-wave chargers only. Otherwise, keep your board in the car and wait for the change.

Rusty.
