The Lowdown
Howdy, Rusty here. Let’s break down what’s cookin’ at Udo Shrine over the next two weeks. It’s a bit of a slow burner, but there’s one day that’s gonna fire.
First up, the early days are pretty tame. Saturday morning (29 August) has a small easterly swell at 2ft with a 12-second period, and cross-off winds. Water temp is 84°, nothing unusual for the time of year. Energy is moderate (300). Afternoon swell picks up a bit but the period tanks to 7 seconds – not worth your time. Sunday is similar, small and flat-ish.
Monday (31 August) through Wednesday (3 September) is a total washout. Onshore winds, building swell, and choppy, messy conditions. Swell climbs from 6ft to a massive 13ft by Thursday morning (3 September). Energy is in the thousands (3735), but the wind is all wrong – heavy cross-onshore. This is a kite-surfing setup, not a paddle session. Thursday afternoon holds at 13ft, still rough.
Friday 4 September afternoon sees a change – the wind turns cross-off from the south, swell stays at 13ft with a 10-second period. Better, but still a big, powerful wave. Only for the experts.
The real gem – and I mean the one to wake up early for – is Sunday morning, 6 September. Swell hits 16ft from the east with an 11-second period, energy is absolutely cranking (5652). And here’s the kicker: glassy, dead-calm wind. That’s a rare combo for a reef break this size. Perfect, clean, hollow rights for the experienced crew only. This is a serious groundswell, and on a reef like Udo Shrine, it’s gonna produce world-class waves.
After that, Monday 7 September morning still has 12ft with glassy conditions – a solid follow-up for advanced surfers. The rest of the week fades in size and picks up onshore wind again, with thunderstorm risks through to Saturday 13 September. Not much to get stoked about.
Bottom line: the first few days are small and the middle of the week is blown out. The absolute best is Sunday 6 September morning – glassy, big, and clean. Monday morning is still good but smaller. The long-range stuff is less exciting and more uncertain.

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.
