The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Udo Shrine over the next couple of weeks. I’ve gotta be straight with you – this is a grim run. There’s not a single day in the 16-day window that I’d call good for a proper surf. Nothing’s lining up for us.
The overall pattern is pretty poor. We’ve got a mix of stormy weather, heavy rain, and a lot of wind that’s either cross-onshore or blowing straight onshore. The swell’s there at times, but the conditions are just a mess. For the first week, Thursday the 3rd through to Wednesday the 9th, it’s a write-off. Strong breezes, near gale-force winds, and constant “poor surf conditions” labels. Even on the 3rd when the swell hits 8 ft from the SE, the wind is howling from the ENE at 12–16 mph, blowing right onshore. The water temp is 84°, which is about average for this time of year, but you won’t care about that when you’re getting blasted by wind and dodging thunderstorms.
There’s a bit of a lull in the middle. Thursday the 10th morning shows a slight air with light cross-onshore and a 4 ft ESE swell, but it’s only marginal and the afternoon gets ruined again. Then Friday the 11th and Saturday the 12th are a mix of risk t-storms and cross-on breezes. Nothing good. The whole period from the 3rd to the 17th is basically a 14-day gap with no proper recommendations. By Tuesday the 15th we get a fresh breeze and 6 ft from the E, but it’s cross-onshore and messy. The last few days – 17th and 18th September – show some improvement on the wind, with lighter breezes and onshore, but still only marginal at best.
Honestly, the best you’re going to get is Thursday the 17th morning. The wind’s just a slight air, almost glassy, with a 4 ft swell from the E at 9 seconds. It’s cross-onshore, but light enough that it’ll be clean. The combined energy is moderate (314), and the wave comment says questionable tide conditions, so you’d need to pick your moment. This is a reef break and it’s inconsistent by nature, so don’t get your hopes up too high.
Other than that, Thursday the 10th morning is another marginal window – 4 ft, light cross-onshore, but it’s still just a “light cross-onshore with small wind ripples,” so it’s not exactly pristine. Udo Shrine is an exposed reef, so it can handle swell, but it needs the right direction and the wind needs to cooperate, and neither is happening here.
If you’re a beginner, the swell never goes over 5 ft after the first couple of days, so it’s not too big for you, but the conditions are just not beginner-friendly with the rain and lumpy seas. For experts? There’s nothing worth the paddle.
We get a few long-period swells around the 12th and 13th with 14-second periods – that’s proper groundswell – but the wind spoils it. That kind of period, with a SE or NE swell, should offer good shape at a reef, but not when it’s cross-onshore and choppy.
This is one of those blank runs that’s pretty normal for the area when the winds are this persistent. It won’t stay poor forever, but for now, I’d save the wax.
Rusty.

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.
