The Lowdown
Alright, Rusty here again.
First off, it’s a quiet start. For a long stretch, through to the end of August, we’ve got small, wind-affected surf. Swell heights are mostly under 3ft, with weak energy readings mostly under 100. Winds are cross-onshore out of the east or north-east, keeping things choppy and poor. On the 16th (Sunday) there’s a bump to 3ft from the east, 10 second period, but onshore wind messes it up. On the 19th (Wednesday) the swell hits 5ft, but with a short 8 second period and choppy cross-on wind – not much to write home about. That setup looks more fun for a kite surfer.
The real payoff is at the very end. The standout is Udo Shrine on Monday the 24th of August. The morning is glass flat (WSW 3 mph), offering a clean 3ft south-east groundswell with a very long 18 second period. Energy is solid at 749, and the afternoon picks up to 4ft with a 16 second period and clean conditions (806 energy). Water temp is 83°F, pretty normal for the time of year. Just know, this spot is inconsistent and crowds are common, so don’t expect solitude.
Tuesday the 25th morning is glassy again with a 4ft east-southeast swell at 13 seconds, good energy (421). Wednesday the 26th morning sees another glassy start with a 4ft east-southeast swell at 13 seconds, solid energy (535). And Thursday the 27th morning is dead calm with a 5ft east swell at 12 seconds, glassy and clean, strong energy (637). Those mornings from the 24th through the 27th are your best bets.
That’s the run-down. Rusty, signing off.

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.
