The Lowdown
Alright, surf is a bit of a mixed bag here for the next couple of weeks. The real standouts are tucked away in the first week and again right at the end of the window, so you've gotta be patient. Let's walk through it.
The first real chance we get kicks off on Thursday the 27th of August. It starts a bit rough in the morning with a choppy cross-onshore breeze, but the Thursday afternoon session is where it's at. We've got a 6 ft swell out of the SSE with an 8-second period. The wind is a light offshore, cleaning the waves up nicely. It's not huge, but the conditions are looking very good for getting out there.
Then Friday the 28th of August is another good one, especially the morning. The swell has dropped to a cleaner 4 ft from the SSE, with a light offshore breeze. The water is warm at 84°, which is about normal for this time of year, so no surprises there.
Look, Udo Shrine is a reef setup that's inconsistent, so you've got to pick your moments. It's exposed to the south and works best with a southerly direction, which lines up nicely here. The combined swell energy is moderate (313), which tells you there's enough push without being too crazy.
From there, things go quiet. We get a few small, clean days over the weekend with tiny 2 ft to 2 ft E swells, and even a glassy morning on Sunday the 30th of August, but the energy is low—just 185 to 218. You could still get a longboard out, but it's not going to set the world on fire.
Then we hit a rough patch. From Monday the 31st of August through to Thursday the 3rd of September, it's mostly blown out. Strong onshore winds, messy conditions, and some building swell that's unrideable. A stormy mess.
Things start to look up again on Friday the 4th of September. That morning we get a 4 ft S swell with a 11-second period and a clean offshore WSW breeze. The sort of conditions that make you want to call in sick. It's not big, but it's clean and lined up. That afternoon looks similar.
Saturday the 5th and Sunday the 6th are a write-off again with cross-onshore winds, but then Monday the 7th of September offers up another decent morning. A 4 ft SSE swell, light offshore wind, and clean surf. The energy is moderate (316), and it's about as good as it gets in this stretch.
The last few days fade out into smaller, cross-onshore slop. If you want the best, your windows are Thursday the 27th afternoon, Friday the 28th morning, and Friday the 4th of September—those are the standouts. Just remember, the reef can be picky, so pick your tide right.

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.

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.
