The Lowdown
G’day, I’m Rusty, and I’ve been staring at this stretch of coast for a long time. For the next 16 days, it’s a real mixed bag out at Udo Shrine. The water’s sitting at 84° with a positive anomaly of 0.8°, so it’s a touch warmer than usual for this time of year, but nothing wild.
The forecast kicks off this Friday afternoon, the 4th of September. There’s a risk of thunderstorms, and a 7ft south swell is rolling in with a 10-second period and a solid 1114 energy reading. The wind is light and cross-onshore, so it’s a bit lumpy. It’s not the cleanest start, but the size is there for more experienced surfers. This spot is a reef, and it’s inconsistent, so it doesn’t break often, but when it does, it can be worth the wait. Just be aware that crowds are often here.
Saturday the 5th sees a drop in quality. The wind becomes a fresh onshore breeze, and the swell fades to 5ft with a short 8-second period. By Sunday, the 6th, a strong breeze is making a mess of tiny 1.0ft waves. This stretch is a write-off for paddle surfing, honestly. The next few days, right through to the 10th of September, are all poor conditions with cross-onshore winds and lumpy, choppy surf. The swell is inconsistent and small, nothing to get excited about.
There’s a brief glimmer on Wednesday morning, the 9th of September. The wind drops to glassy, and the swell is 4ft from the southeast with an 8-second period. The energy is at 180, which is moderate. It’s surfable, but ordinary. It’s the only clean moment in a long run of bad days.
The second week of the forecast is a bit of a desert. From the 11th through to the 16th, it’s mostly poor surf with weak to moderate energy, small waves, and unfavourable winds. Lots of cross-onshore and onshore conditions. The 15th of September has a 5ft east swell with a 13-second period and 990 energy, but it’s onshore and rated poor. The 16th is similar with marginal conditions.
The true standout appears on Thursday the 17th of September. The morning is glassy calm, with a 3ft east swell at a 9-second period and 215 energy. It’s small, but the conditions are perfect. The wind is nil, the water is clean. For a spot that’s inconsistent, this is a promising window. The afternoon holds up with a 2ft, 12-second period swell and glassy conditions, though the energy drops to 184. For a break that rarely delivers, this Thursday morning is the best on offer, but it’s small and better suited to longboards or funboards.
The 18th and 19th of September see the window close. The 18th has glassy surf in the morning but the waves are tiny, and by the afternoon, the wind shifts to a light cross-off but the swell is too small to matter. The 19th is a poor end to the outlook.
Overall, the only real standout is the 17th of September. It’s a long-range call, so take it with a grain of salt, but if the forecast holds, it’ll be a clean, uncrowded morning for the crew that’s patient.

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.
