Onrus Surf Forecast and Surf Report

Alright, the surf crew. Rusty here, and I’ve been staring at the charts for our local zone. Let’s get into it. We’re looking at a bit of a slow start here. The first recommendation worth paddling out for isn’t until Monday the 14th, so we’ve got a few days of waiting. After that, there are some real windows of opportunity, but we also have to wade through some messy conditions.

The standout session in the whole 16-day forecast looks like it’ll be Sunday morning the 20th. That’s almost a week and a half out, so keep an eye on it, but if it holds, it’s the one to circle on the calendar.

Let’s start with Onrus. This is a reef break, intermediate territory, and inconsistent. It likes a SW swell, which is what we’re getting. The water temp is sitting pretty average for this time of year, nothing wild for the first break we’re talking about.

For Monday the 14th, we finally get a window. The morning is a bit marginal with a 4ft WSW swell and a 12-second period. The wind is a fresh offshore from the NW at 19 mph, which will keep things clean, but it's a lot of wind. The real action picks up in the afternoon. The combined energy hits moderate at 588, with a 6ft swell from the WNW. The period is a short, choppy 7 seconds, so it won’t have much grunt, but a moderate offshore at 16 mph should clean it up. It’s a score of 3 out of 10, which is the best we’ve seen so far, but it’s not a classic.

Tuesday the 15th looks frustrating. Strong offshore winds up to 28 mph will have the surface clean, but the waves are going to be hard to paddle into. The morning has a tiny 2ft swell with a very long 19-second period, and the afternoon sees 5ft with a 16-second period. That long period groundswell is nice energy (moderate at 1903 combined energy in the afternoon), but with that much wind, it’s a battle. Just marginal.

We get a bit of a lull of poor conditions from Wednesday the 16th through to Saturday the 19th, with onshore winds and lumpy surf. The swell sticks around, but the quality is bad.

Now, the highlight: Sunday morning the 20th. This is the one. The combined swell energy is moderate at 1889, with a solid 7ft swell from the SW and a 13-second period. That’s a proper, punchy groundswell. The wind goes glassy – yes, glassy – with a slight air from the SSE at 3 mph. The report says “excellent surf conditions for experienced surfers” with a score of 4 out of 10. At 7ft, this is getting into expert territory, especially on a reef. It’s going to be clean, powerful, and for the crew that knows what they’re doing, it’s the best on offer. The weekend crowd could be a factor, so get in early.

Monday the 21st still has surf, with a 7ft SW swell, but the cross-onshore wind is going to rough it up a bit. Still, a 3 out of 10 for the morning makes it a salvageable fun session if you missed Sunday.

The last week of the forecast looks like a slow taper back to poor conditions and onshore winds, with nothing really shouting for a paddle. The 25th of September has a small chance on the Friday morning with a cross-off shore wind that could clean up a 6ft swell, but it’s a long way off and uncertain.

So, to sum it up: sit tight through the weekend, then keep an eye on Monday afternoon for a little something. But the real target, the one that could be magic, is that Sunday the 20th morning session. Get ready.

Rusty.
