The Lowdown

Alright, folks, Rusty here. Let’s have a look at what’s coming up for Udo Shrine. The next 16 days are a mixed bag, with a lot of flat, choppy, or just plain messy conditions to sit through before we get a shot at some real size.

Udo Shrine is an exposed reef break, and it’s inconsistent, so it doesn’t fire often. Right now, we’re in a long dry spell. From Thursday the 10th of September right through the entirety of the following week, the surf is a no-go. We’re looking at a solid 10-day stretch of poor conditions. The swell is small, mostly under 5ft, and it’s coming from the SE or E, but the wind is a relentless cross-onshore from the NE or NNE. The water temp is sitting at 83°, which is bang on average for this time of year. The combined energy stays weak to moderate, with the highest a few days around 377 (14 September), but it’s all ruined by the wind. There’s nothing to get excited about here.

We finally see a change on Saturday the 19th of September. A big ESE swell pushes in, starting at 10ft in the morning and building to 13ft by the afternoon. The period is a very long 18 to 19 seconds. This is proper groundswell energy, and the combined energy skyrockets from 6363 up to 9831. Now, the wind is still cross-onshore from the N and NE in the morning, but in the afternoon swings to a light onshore from the ENE. That’s still not perfect, but the sheer size and power make it a standout for experienced surfers. This is a big, powerful reef wave, and with a 13ft swell and that long period, it’s going to be heavy and only for experts. The break is inconsistent, so don’t expect a wave every set, but when they come, they’ll be big.

Sunday the 20th of September is the biggest day of the window, but it’s a warning, not a recommendation. The swell hits 16ft to 18ft from the ESE with a 17-second period. The combined energy is a massive 16177 to 16003. This is a monster swell, and even the forecast says it’s too big for this break. Wind is cross-onshore from the NE at 12 mph, so it’s going to be a dangerous, chaotic mess. Only the most experienced, heavy-water surfers would even consider it, and even then, it’s a high-risk call.

After that, the energy drops fast. Monday the 21st has an 11ft swell but strong onshore winds from the ENE at 15 to 18 mph, making it poor. The wind then goes wild, with a severe gale and even storm force winds from the SSE on the 23rd, completely destroying any hope of surf. There’s a brief window on the 24th with clean offshore winds from the WSW, but the swell is tiny at 1ft, so it’s flat and clean. Not worth a paddle.

So, the only real standout in this whole 16-day forecast is Saturday the 19th of September. If you’re an expert looking for a big, powerful reef wave, that’s your window. For everyone else, it’s a long wait.

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.
