Onrus Surf Forecast and Surf Report

Right then, let’s have a look at what’s heading our way for Onrus.

We’ve got a bit of a classic setup here for the next couple of weeks. The first few days are going to be a write-off unless you’re a madman – a big, powerful SW groundswell is going to be way too chunky for the reef. That big energy (3257) on Tuesday the 1st is just too much, and the swell is 10ft, so that’s a hard pass for anyone but the most experienced. Even the glassy Wednesday morning (2nd of September) with that 10ft SW swell and 13-second period from the south-west is going to be a beast. The wind is perfect, absolutely glassy, but the swell is just too meaty for the break. The water temp is sitting at 59°, which is about average for the time of year.

After that, we get a messy run of onshore winds from Thursday through to the weekend. The energy drops (between 340 and 1636) but the wind is just rubbish, especially Friday and Saturday with strong cross-onshore winds up to 28 mph. Not worth paddling out for.

The good news starts to arrive from Monday the 7th. The morning session is the pick of the whole run. The wind is a clean, light offshore from the WNW, and the swell has dropped to a manageable 4ft from the SSW with a solid 14-second period. That’s proper groundswell, and with the reef at Onrus, those long-period lines will bend in nicely. The energy is still moderate (863), but it’s clean and the forecast is for very good surf. Get in the water early. The afternoon is a bit windier, but still okay.

The rest of the first week and into the second is a bit of a mixed bag. Tuesday the 8th has clean surf in the morning with a 3ft SSW swell, and Wednesday the 9th is similar but smaller. These are good, clean options for a quick session, but nothing to write home about.

Then the wind turns nasty again from the 10th, with a few days of onshore slop. The energy picks up a bit, but the wind is cross-on and messy. Not the time to be out.

The final window of interest comes on Saturday the 12th. The morning looks clean with a light offshore breeze and a 4ft SW swell. The afternoon has a bit more size (6ft) but the wind goes cross-shore, so it’s a bit of a gamble.

Looking further ahead, the 16th of September shows a big pulse of long-period SW swell (16 seconds, 2732 energy) arriving, but the wind is from the east and cross-on, so conditions are likely to be messy. This one is a distant promise, but it’s not looking like a classic.

So, the standout? Without a doubt, Monday morning, the 7th of September. The glassy conditions, the clean offshore wind, and that solid SSW groundswell will make it the best waves of the entire forecast. The crowds are listed as “sometimes” at Onrus, so on a good day like this, you might share it with a few others, but it’ll be worth it.
