The Lowdown

Alright, this is Rusty. Let’s talk about Udo Shrine. We’ve got a long outlook here, stretching 16 days, and honestly, it’s a bit of a slow burn. The first half of the period is pretty lackluster with mostly small, messy surf and onshore winds, so don’t get your hopes up too soon. There’s a real gap of about a week where conditions are just poor or marginal for paddling. Then things start to clean up nicely in the second week, especially around the 24th and 25th, which look like the real standouts.

For context, the water temp is sitting at a warm 83°F, which is pretty much normal for this time of year, so no need to worry about a wetsuit.

Right now, starting from Friday the 14th, it’s a bit of a dud. Udo Shrine has a tiny 2ft swell from the south, with a short 8-second period and weak energy (62). On top of that, we’ve got a cross-offshore wind that’s trying, but the waves just aren’t there. This pattern sticks around through the weekend and into the start of the following week. Saturday the 15th and Sunday the 16th offer a little knee-high south swell, but it’s cross-on and bumpy. The energy stays weak (under 100), and it’s all showing as poor surf conditions. Monday and Tuesday are more of the same – a bit of east swell showing up around 3ft, but it’s onshore and choppy, not worth paddling out for.

We hit a few days of better energy from Wednesday the 19th through Friday the 21st, with swell heights bumping up to 4ft to 4ft, but the wind is mostly cross-onshore and moderate, so the surface is messy. Still not the good stuff.

Things start to turn around by Sunday the 23rd. On Sunday morning we get a clean, cross-off wind with a 2ft east swell, and it’s described as surfable – not great, but a step in the right direction. The real turn comes on Monday the 24th of August. This is the first standout. We’ve got a 3ft east swell with a 9-second period, and the real winner is the wind: glassy, glassy, glassy with a northwest breeze at just 3 mph. That’s practically perfect conditions for a reef break like this. The energy is moderate (302), and it’s set to be good surf conditions.

Then, Tuesday the 25th of August is the absolute highlight. Early morning has a 4ft swell from the east-southeast, but the period jumps to a very long 14 seconds – that’s proper groundswell energy. The combined energy is strong at 591. And again, glassy conditions with a light NNE breeze. This is the session to aim for. The swell direction (ESE) is a good match for Udo Shrine’s optimum south, and that long period should wrap in nicely on this reef. Keep in mind, with that long period, it might break a little straight on a beach, but on a reef setup like this, it’s going to be clean and lined up. That afternoon gets a bit cross-shore and bumpier, so stick to the morning.

Wednesday the 26th brings the biggest swell of the period – 6ft from the east with a 14-second period. That’s strong energy (1172), but it’s coming with a cross-onshore wind, making conditions more marginal. This is expert territory at that size. For the rest of that week, Thursday the 27th morning is glassy with a solid 4ft east swell and good energy (400) – a solid consolation if you miss the Tuesday peak.

After that, from Friday the 28th onwards, we get heavy rain and onshore winds again, with the swell dropping back to under 3ft. That’s the end of the run.

So bottom line: the first week is a write-off. The second week has a couple of absolute gems. If you can get out on the 24th or the morning of the 25th, you’re in for some of the cleanest, most lined-up waves of the month. Just watch the crowds at Udo Shrine – it can get busy, so get in early.

Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
