Onrus Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s cooking for our local break, Onrus.

We’ve got a bit of a slow start, but the payoff is coming – a proper South-West groundswell is building. The first decent window is Monday morning, September 7th. The water is feeling way colder than normal for this time of year, so you’ll want a thick wetsuit.

Monday morning, September 7th, is our first real nod. Onrus is waking up with a solid 6ft SW groundswell, packing serious energy (1325). The wind is glassy, dead calm out of the WNW. It’s going to be clean, powerful, and lined up. This is an intermediate reef break, but at that size with a 14-second period, it’s going to be heavy. Not one for the beginners – leave it to the crew who know the reef. Crowds are sometimes around, so you might have a few mates out, but it’ll be worth it.

Swell drops back Tuesday, September 8th, through Wednesday, but the quality is shot with cross-shore winds. By Thursday morning, September 10th, a bigger pulse hits: 8ft SW at a long 15 seconds, with a huge energy jump (2590). But the catch is the onshore wind – it’s cloudy and messy, marginal at best.

The real standout, the session to circle on your calendar, is Wednesday afternoon, September 16th. Don’t let the morning rain fool you. By afternoon the wind goes glassy, and we’re looking at 8ft of SW swell with a very long 15-second period. The combined energy is massive (5546). This is exceptional, but it’s a big-wave day – expert territory only. That long period will focus perfectly on this reef. If you’ve got the skills, this is the session of the fortnight.

Before that, on Tuesday morning, September 15th, the offshore wind from the NW cleans up a 5ft SW swell. A solid, surfable morning. Then Tuesday afternoon the swell jumps to 10ft from the W with a short, fat 8-second period – too big and too short to hold shape here. That’s more of a kite session than a paddle one.

After the big Wednesday, it gets blown out with strong onshore winds through the end of the week. The following Sunday morning, September 20th, offers a last clean window with 7ft SW swell and glassy conditions – another good expert session, but the real magic is that Wednesday.

So to wrap it up: The best swell of the whole 16 days is Wednesday afternoon, September 16th. But jump on Monday morning, September 7th, for the first clean ride of the run. The second week is mostly a write-off with wind, so keep an eye on Tuesday 15th and Sunday 20th as backup clean-ups.

Rusty out.
