Onrus Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s on the table for Onrus over the next couple of weeks. It’s a bit of a rollercoaster, so stick with me.

First up, the water temperature here is about average for this time of year, nothing out of the ordinary. The protected reef setup at Onrus is a classic, but it's an inconsistent wave that needs a good SW groundswell to light up.

We’re starting off with a pulse of solid energy this Thursday (10th). The combined swell energy is ripping at (2061). We’re looking at a 7ft SW groundswell with a very long 15-second period. The problem is that cross-onshore wind is going to mess with the surface. It’s a bit of a tease – the power is there, but the conditions are marginal. Friday and Saturday are a total write-off with strong onshore winds and choppy, lumpy junk. The swell gets even bigger Saturday afternoon, hitting 10ft from the SSW with a 16-second period and huge energy (4671), but the wind is just too strong and onshore. A no-go for paddling, and honestly, that setup looks more interesting for kite surfing than a proper paddle session.

We’ve got a dry spell for a few days here. The real turnaround comes late Monday (14th) and into Tuesday morning. The wind finally swings offshore – a clean, fresh NW breeze. Monday afternoon gives us a 5ft, clean wave with a shorter 8-second period, but the wind is offshore and it’s clean. Tuesday morning (15th) is the standout for the early part of the window. We’ve got a 2ft SW groundswell, but a very long 21-second period – that’s serious energy running deep. The wind is fresh offshore and clean. This is a true glassy, long-period groundswell that will wrap beautifully around the reef. The energy is moderate (656), but the quality will be high. It’s a smaller day, perfect for intermediates. Keep in mind that a long period like that can make the sets a bit shifty on the reef, but that’s where the magic lives.

The big boys show up again on Wednesday (16th). A 10ft SW swell with 14-second period is predicted, but the note says it’s simply too big for this break. Combined energy is monstrous (4226), but this is for experts only, and even then, it might be a washing machine. The wind is onshore too, so it’s a pass.

We get a few more days of choppy, cross-onshore wind again through the end of the week, with some moderate energy (1646 on Thursday). Friday (18th) afternoon flattens out a bit but the wind goes light.

Looking into the second week, the real promise is a long way off. On the 24th (Thursday) and 25th (Friday), we see another change. The wind goes offshore again – NW on Thursday and WNW on Friday. The swell is smaller, around 4ft to 4ft, with a solid 15-second period. The energy is moderate (700 range), but conditions are described as "very good." This is the best bet for the back half of the forecast. It’s a long way out, so don’t bank on it, but it’s a promising light at the end of the tunnel.

So, the true standout is the Tuesday morning (15th) session – that 21-second period groundswell with offshore wind is a rare treat. The second best, and more reliable for the less confident, is the Monday (14th) afternoon. For the second week, keep an eye on Thursday 24th and Friday 25th for a clean, smaller window.

Rusty out.
