Onrus Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s coming up at Onrus.

First up, a heads-up: the water temperature is sitting at 15°, which is about average for this time of year, so nothing too wild on that front.

The forecast starts off a bit rough. Wednesday the 26th is a write-off with a strong cross-onshore wind making things lumpy and messy – definitely not one for the board. You’ll want to wait until Thursday the 27th. That morning, we’ve got glassy conditions with a 5ft swell from the S, period at 12 seconds, and the combined energy is strong at 1117. It’s excellent surf for experienced surfers – clean, with a bit of power. The afternoon stays clean too, with a cross-offshore breeze and a 5ft swell.

Friday the 28th is still decent, especially the morning with glassy conditions and a 4ft S swell (493 energy). It’s more mellow but clean. Saturday the 29th morning looks good again – clean, cross-off wind, 3ft swell from the WSW (635 energy). But Saturday afternoon gets messy with a rising wind and a 6ft swell, so that’s a pass.

Sunday the 30th has some size – 8ft in the morning, but it’s cross-shore and a bit lumpy, not the cleanest. By Monday the 31st, we’re back to clean conditions with a cross-off breeze and a 6ft swell from the SW (865 energy). That’s a solid session for intermediates.

Now, here’s the standout: Tuesday the 1st of September. The swell jumps to 10ft from the SW, with a period of 14 seconds, and the combined energy is a massive 3893. That’s a serious groundswell. The wind is fresh offshore from the NNW, so it’ll be clean. But fair warning – at 10ft, this is for experts only. The reef setup at Onrus should handle it, but it’s not a day for the faint-hearted. The afternoon is even bigger at 13ft, so if you’re skilled enough, that’s the pick of the whole forecast.

After that, the surf quality drops fast. From Wednesday the 2nd through to Saturday the 5th, it’s mostly onshore wind, choppy, and messy. There’s a lot of size (10ft to 12ft), but the wind kills it. Sunday the 6th stays poor. You’ll get a brief window on Monday the 7th – glassy and clean, with a small 3ft swell from the SW – but it’s tiny. The rest of the second week is mostly marginal, with a few cleaner moments but nothing that really stands out. By Thursday the 10th, we’re looking at another 12ft SW swell with clean wind, but again, that’s expert territory and the wind is onshore from the SE, so it’s not ideal.

Overall, the best bet is Thursday the 27th morning for a clean, fun session, and Tuesday the 1st of September for the big, expert-level groundswell. The first week has more to offer than the second, which fades into smaller, messier conditions.

Stay safe, and keep an eye on that Tuesday swell.

Rusty.
