The Lowdown
Alright, Rusty here with the rundown for Rossbeigh Strand.
We’ve got a quiet start, with the first couple of days offering nothing but tiny, weak energy and messy conditions. The first real window doesn’t open until Wednesday, August 12th. So, get the coffee ready, because we’re waiting.
Wednesday morning, August 12th, shows some promise. There’s a clean cross-off breeze from the SSE, making the surface look good. The swell is a modest 1.4m from the SW, but it’s only got a short 9-second period. The combined energy sits at 349, so it’s moderate. It’s not firing, but it’s clean, and for the beginners that this spot is made for, it’s a decent morning to splash around. The afternoon sees the wind shift, getting a bit choppier.
Thursday, August 13th, is much the same: 1.4m swell, but the wind is more side-shore. It’s okay, not special. Friday and Saturday look like they’ll be blown out with onshore breezes and chop.
Now, lock in for Thursday, August 20th. The morning is your standout session for this whole forecast. We’ve got a light, clean cross-off breeze from the NNE. The swell is a nice, manageable 1.0m from the west, with a 9-second period that’ll give you a bit of push. The energy is 321 (moderate). The water temp is about normal for this time of year. It’s clean, it’s small, and it’s perfect for a longboard or a funboard session at this break.
But then, Friday, August 21st, the ocean wakes up. The swell jumps to 3.5m from the WNW, with a 10-second period. The combined energy is a massive 2746 – that’s very strong. The wind is light and side-shore, but look, that’s just too much juice for Rossbeigh. The data confirms it: it’s too big for this break. That’s for experts only, and even then, it’s gonna be a heavy, powerful closeout in places.
After that, it’s a steep drop-off. Saturday, August 22nd, is a rainy, onshore mess. By Sunday, we’re back to tiny, weak swell that’s not worth your time.
So here’s the bottom line: your best bet is the morning of Thursday, August 20th. It’s the most user-friendly, clean session on the board. The Friday, August 21st swell is a spectacle, but it’s a big-wave day that’s not for the faint of heart. For the rest of the run, it’s pretty quiet.
Rusty.
