The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Udo Shrine over the next couple of weeks.
Honestly, I’m looking at the charts and my heart sinks a little bit. We’ve got a long wait ahead. The first surfable day on the cards isn’t until the morning of Sunday the 6th of September. That’s a gap of nearly two weeks of nothing but onshore wind and messy conditions. We have to get through a period of big, unruly swell and stormy winds first.
The real story here is a big pulse of southern hemi swell that hits on Tuesday the 25th of August. We’re talking 13ft of swell from the SE, with a combined energy of 6835 – that’s strong, powerful stuff. But the wind is a cross-onshore 12 mph, making it choppy and poor. This is expert-only, big-wave territory at best, and honestly, it looks more interesting for a kite surfer than a paddle surfer. The energy stays strong through the 26th and 27th, but the wind stays onshore or cross-shore, and the wave periods start dropping below 8 seconds, which is just weak, short-period wind chop. It’s a write-off.
We finally get a chance on the morning of Sunday the 6th of September. The swell has dropped right back to 3ft from the S, but the wind is a clean offshore from the WSW at 9 mph. The water temp is sitting at a very pleasant 84°, which is about normal for the time of year. The combined energy is weak at 197, so it’s small, but it’s clean. The Sunday afternoon shows a 3ft swell from the E with a moderate offshore wind. It’s not going to be a classic, but it’s surfable.
Then, Monday the 7th of September is the real standout. For the morning, we’ve got glassy conditions with a 3ft, 10-second swell from the E. The wind is a flat calm, glassy 3 mph from the NW. The combined energy is just 171, so it’s tiny, but with glassy conditions, those little waves will be clean as a whistle. This is a long-period groundswell for the size, so it’ll have a bit of shape, but at a beach-and-reef setup like this, it might break a little straight. Still, for a small, clean session, that’s the pick of the entire forecast. The afternoon turns to a cross-onshore, so get in the water early.
The long-range stuff looks like a no-go. From the 8th of September onwards, the wind is back onshore and the swell is small and messy. The only other flicker is on the 6th, and that’s about it. It’s a tough call for the next two weeks, but if you can sneak out on Monday the 7th of September morning, you might get a few clean little ones.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Udo Shrine may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
