The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for Udo Shrine.
Straight up, this is a tough outlook. The next week and a half is a write-off for anything decent. We’ve got a solid run of poor conditions right through to the 10th of September. The wind is howling from the NE onshore for days, with heavy rain and even a risk of thunderstorms. The swell is all over the shop, hitting 15 ft on the 5th, but it’s chopped up and messy. Don’t bother paddling out, that setup over the sand and rock looks more interesting for kite surfing than paddle surfing right now.
We finally see a chance of something glassy on the morning of Friday the 11th. Winds go glassy, but the swell has dropped right out to just 3 ft from the ESE. The water temp is around 84°, which is about average for the time of year, so at least a dip will be warm. It’s only scoring a 2 for surf quality, and it’s inconsistent here, so keep expectations on the floor.
The real standout, and the only one worth circling on your calendar, looks to be the afternoon of Tuesday the 15th of September. That’s a week and a half away. The swell is pumping up to 15 ft from the E, with a very long 14-second period. This is proper groundswell energy, with a combined energy reading of 9255. That’s strong to very strong. The wind is light and onshore, but for a spot this exposed, clean faces are going to be hard to come by. The score is high, and it’s the only one in the whole window. Just be warned, at this size it’s only going to be for experts, and a long period swell like this can break a bit straight at a beach setup. It’s a big gamble this far out, but it’s the best we’ve got.
After that, the 16th shows 13 ft E swell with clean, cross-off winds in the afternoon, and the 17th has 10 ft E swell, but the winds get a bit sketchy again. The real focus is that Tuesday afternoon.
Rusty.

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.
