The Lowdown

Alright folks, Rusty here. Let's cast an eye over what Udo Shrine has cookin' for us. I gotta be straight with you, it’s a bit of a mixed bag looking out over the next couple of weeks.

The early part is rough. We've got some swell on the way, but the wind is a real drag. For the first week and a half, from Sunday the 23rd right through to the start of September, the conditions are mostly poor. There’s a lot of onshore and cross-onshore wind messing things up. We see a building swell, hitting a massive 15 ft by Tuesday the 25th, but it's blowing 16 mph from the NE, making for choppy, blown-out surf. That kind of size is really only for experts anyway.

It stays windy and messy for days. We do see a couple of windows described as "marginal" on Monday the 24th with a 7 ft SE swell and Monday the 28th with a 10 ft SSE swell, but truth be told, the wind just isn't your friend.

Now, hold onto your board, because the real story starts on Friday the 4th of September. The swell absolutely detonates, hitting a massive 23 ft from the SE. The thing is, the data says the tides and wind are favorable, but that’s a biblical-sized wave for Udo Shrine. It's simply going to be too big to surf safely or enjoyably. Even the experts would be pushing their luck. That same day sees wind ramping up to a nasty 43 mph, so that’s a flat-out hard pass.

Then, finally, a light at the end of the tunnel. Saturday the 5th of September morning is your window. The swell drops back to 5 ft from the ESE, and crucially, we get a solid 16 mph offshore wind from the West. That’s clean wave faces, my friends. That’s the standout, make no mistake. It’s a proper window of quality.

Following that, Sunday the 6th of September morning looks pretty tempting too. It's just a small 3 ft S swell with glassy conditions, meaning flat, clean water. It won't have the punch of the day before, but for a quiet, tidy session, it’s hard to beat those conditions.

So, to wrap it up: the first week is a write-off thanks to wind. The huge swell on the 4th is a monster best left alone. Saturday the 5th is your best chance for a proper session with that offshore wind cleaning up a 5 ft ESE swell. Sunday the 6th is a smaller, glassy second option.

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.

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.
