The Lowdown
Alright, Rusty here. Let's break it down.
We're looking at Udo Shrine, a reef break that doesn't break often. The whole 16-day window is a tough one, to be honest. The surf is either non-existent or blown to pieces, with a few big swells that are just too much for this spot. There’s a short window on the first day, Tuesday the 15th of September, that’s the only real chance for a paddle, but after that, we’re looking at a long, frustrating stretch.
The best of what's on offer is Tuesday morning. We’ve got a 5ft swell coming from the ESE with a 10-second period, pushing moderate wave energy into the break (460). The wind is glassy from the north at 3 mph. That's a rare gift for a spot that's often crowded. The water temp is about average for this time of year. The waves will be clean and the sets will have a little push, but remember, this break is inconsistent, so you might have to wait your turn. It’s a gamble, but with conditions this clean, it’s worth the look.
Tuesday afternoon, the wind swings cross-shore and the quality drops. By Wednesday the 16th, it's a write-off with cross-onshore wind and choppy conditions. From Thursday the 17th all the way through to the end of the month, it’s a bleak picture. We see a massive swell pulse on the 20th with a 20ft+ swell and near gale-force winds—that’s a kite-surfing setup, not a paddle session. The energy readings are off the charts (29,300+), but the wind and size make it unsurfable on a reef. There’s a tiny bit of clean offshore wind on the 23rd, but with a 1ft swell, there’s just nothing to ride.
Honestly, if you don't get in the water on Tuesday morning, you might as well hang the board up for a while. The forecast can always change, but as it stands, this is a classic example of a blank run for this area. Udo Shrine is a fickle spot, and this outlook proves it.
Rusty.

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.
