The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s happening at Udo Shrine over the next couple of weeks. Gotta be straight with you – it’s a rocky start and a long gap before things get even worth mentioning.

We’re looking at a solid run of poor conditions kicking off Tuesday the 1st of September with onshore winds and messy 4ft to 5ft SSE swell at a short 8 seconds; combined energy is weak to moderate (224-333). Not worth paddling out. Wednesday and Thursday get bigger but it’s all wind-affected with strong onshores, and by Thursday afternoon we’re looking at a messy 10ft SE swell (1745 combined energy) but under heavy rain and 25 mph onshore wind – that’s a hard pass for paddle surfing, more of a kiter setup if anything. Friday the 4th sees a brief marginal window with 6ft SE swell (754), cross-shore wind, but still riddled with storms. After that it drops right off into tiny 1ft-2ft lumps over the weekend with onshores – no hope there.

Then Monday the 7th afternoon we get a sudden spike to 10ft E swell (1863) and light onshore wind, but it’s only rated marginal. Not the cleanest. Tuesday and Wednesday the 8th and 9th stay marginal or poor with onshores and lumpy conditions. That big 10ft E groundswell on Wednesday the 9th (2586 energy, 13 second period) is totally blown out by cross-onshore winds. Same story Thursday with 8ft E swell at 14 seconds – big energy (2536) but messy. Friday the 11th is still rough.

Now here’s the standout, and it’s worth waiting for. Saturday the 12th of September – early morning we get a beautiful window: glassy conditions, 7ft E swell with an 11 second period (1225 combined energy). That’s clean, solid, and perfect for experienced surfers at this exposed reef break (Udo Shrine). Crowds are often here, so expect company in the lineup, but the quality will be worth it. The swell direction is SSE, with the optimum being S, so it’s a bit angled but still working.

After that, Sunday the 13th turns gnarly again with 13ft SE swell (8571 energy) but strong cross-onshore winds – that’s expert only if anyone’s dumb enough, and messy. Then Monday the 14th drops off, but then we get another promising moment: Tuesday the 15th of September morning – glassy again, 8ft SE swell at 9 seconds (1034 energy). That’s a bit shorter period, but glassy conditions make it clean and fun for the experienced crew.

For context, water temp is about average for this time of year, nothing unusual.

So in short: the first week is nearly a write-off. Best on offer is Saturday the 12th morning – that’s your call. Tuesday the 15th morning is also a good runner-up. Everything else is blown out, too small, or just messy.

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.
