The Lowdown
Alright, Rusty here. Let's have a look at what's on offer around Udo Shrine.
To be honest, my heart is a bit heavy looking at this run. The next couple of weeks are looking pretty grim for a proper paddle session at Udo Shrine. Don't get me wrong, the ocean is gonna be pumping with energy, but it's going to be all wrong for us. The set-up is a reef, exposed to the south swell, and this forecast is a long run of choppy, messy, and often downright dangerous conditions.
We start with a few days of small, weak swell. Saturday the 12th and Sunday the 13th have waves around 2 ft, but the wind is cross-onshore, making it bumpy and poor. The combined energy is weak to moderate. It's just not worth paddling out for.
That same theme continues through the early part of the following week. The swell bumps up a touch to 4 ft on Monday the 14th and Tuesday the 15th, but the swell period is a short, weak 9 seconds and the wind stays cross-onshore. The energy picks up to moderate, but the quality is still "poor" with "marginal" conditions at best. It's not going to be fun.
Then things get wild, but not in a good way. From Friday the 18th onwards, the swell really starts to crank up. We see a massive spike on the 19th and 20th, with 16 ft to 20 ft of south-east swell roaring in. The combined energy hits astronomical numbers, but it's a total loss for surfing. The wind is howling onshore at 25-30 mph, turning the lineup into a foamy washing machine. By Monday the 22nd, it gets proper scary with a 30 ft swell and gale-force cross-shore winds. That's not surf, that's survival. Even though the waves are huge, the wind and conditions are making it impossible.
There is one brief flicker of hope. On Wednesday morning, September 23rd, the wind drops to a dead calm, glassy. The swell is tiny, only 2 ft from the ESE with a very long 16-second period. That long period will make it a bit clean and lined up, but it's so small. The combined energy is weak. It's a rare, glassy moment, but you'll be struggling to get a ride. Given the overall run, this is the only time it might be worth a paddle for the sheer peace of it, but don't expect any waves of consequence.
Thursday the 24th and Friday the 25th see the swell jump back up to 8 ft to 10 ft, but with moderate onshore winds. At that size, it's already too big for beginners, but with the wind on it, it's a messy, choppy wall for experts only. The energy is strong. By the weekend of the 27th, we're back to huge, wind-affected junk.
Look, the bottom line is this: Udo Shrine is going to be blown out, too big, or both for nearly the entire 16-day window. There are no standout days for a quality surf. The one glassy morning is a fleeting moment of calm, but the swell is minimal. If the wind wasn't so relentless, the big swells on the 19th would be world-class, but the onshore gales just ruin everything. This set-up looks far more interesting for kite surfing than paddle surfing right now. We'll just have to wait for the wind gods to sort themselves out.
Rusty.

Information about the Udo Shrine Surf forecast
The above surf forecast table for Udo Shrine provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Udo Shrine can be found by selecting the local surf guide option on the grey menu. Our Udo Shrine surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Udo Shrine) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
