Onrus Surf Forecast and Surf Report

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

We’re looking at the next couple of weeks for Onrus, and it’s a real mixed bag. The big stuff is on the way, but you’re going to have to wait through some pretty average days to get to it.

The first real chance to get wet comes early on Monday, 7 September. The swell is dropping from the weekend, but it’s still a solid 6 ft from the SW, with a period of 14 seconds. That’s a proper groundswell, and it’s got plenty of energy behind it. The real kicker is the wind – glassy, dead calm. That’s a rare treat and will make for some clean, lined-up waves. It’s a reef break, so it needs a bit of respect, and it’s inconsistent, so you’ll be sitting and waiting. But when they come, they’ll be worth it. Monday afternoon is a carbon copy, just a touch smaller at 6 ft. This is the standout session of the first week.

After that, things get messy. Tuesday, 8 September, through to Thursday, 11 September, sees the wind shifting onshore and the swell dropping off. We’re looking at lumpy, cross-onshore surf in the 3 ft to 3 ft range. Not worth paddling out for. The wind is just all wrong.

Friday, 12 September, and Saturday, 13 September, bring a bit more size, pushing 7 ft to 8 ft, but it’s onshore, rainy, and messy. The energy is there, but the quality isn’t. You’ll be fighting a chop. Then Sunday, 13 September, morning sees a solid 10 ft wave, but it’s onshore and messy – not a good combo.

We hit a dry spell until the 14th, where the swell is small and the wind is still a problem. On Monday, 14 September, the afternoon shows a cross-shore wind and an 8 ft wave from the WSW, but with a short period of 8 seconds. That’s a weak, blown-out windswell. Not for me.

Now, here’s the second real standout, and it’s a big one. Tuesday, 15 September, morning. The forecast is calling for a massive 13 ft SW groundswell, with a 15-second period. The energy is astronomical. The wind is offshore from the NW, making for clean conditions. This is a serious, heavy swell. For a reef break that’s already inconsistent, this size is for experts only. Beginners and intermediates, stay on the beach. The afternoon keeps the 13 ft, but the wind ramps up to a strong offshore, making it clean but hard to paddle into.

Wednesday, 16 September, stays huge at 12 ft, but the wind swings cross-offshore and then cross-shore, which will put a bit of a texture on the face. Still, that’s serious, powerful surf. The energy is still massive. This is all expert territory.

The end of the window (17th to 21st) sees the swell slowly drop back down, but the wind remains a big problem, mostly onshore and choppy. There’s a tiny window on Sunday, 20 September, with glassy conditions and a small 4 ft wave, but it’s a long way out.

So, to sum it up: your best bet is the glassy Monday, 7 September, for a manageable, clean swell. The real big guns come on Tuesday, 15 September, with a massive, clean, expert-only swell. Keep an eye on that one.

Rusty.
