The Lowdown
Alright, Rusty here again, this time in feet and miles per hour for the local crew.
Looking at Udo Shrine, we’re in a pretty flat stretch right now. The next several days are filled with small, onshore, weak surf. Nothing really worth getting wet for until we hit the end of the month. There’s a big lull in decent waves from now until the final days of August.
Monday the 31st of August is when things finally clean up. The wind goes glassy—dead calm—making for perfect surface conditions. Swell runs about 3ft from the southeast with a 10-second period, and the combined energy sits at a moderate 382. The forecast actually says “good surf conditions.” That’s a rare treat for Udo Shrine. Keep in mind crowds are often an issue here, so get out early.
The big standout is Thursday the 3rd of September. Swell pumps up to a solid 23ft to 24ft from the east-southeast, with a period of 12–13 seconds. That’s a major groundswell, with energy readings shooting up to 17,304 and 15,608—very strong. But at that size, only experts should even look at it. The wind stays cross-onshore to onshore, so it won’t be glassy, but the raw power will be incredible on this exposed reef. Water temp is about 84°F, which is average for this time of year.
For most surfers, that glassy day on the 31st is your best bet. For the heavy crew, the 3rd of September is a beast waiting to be unleashed.

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.
