The Lowdown

Alright, Rusty here, checkin' in from the shores. Let's get the full picture on what's comin' our way for the next couple of weeks.

We're lookin' at a real mixed bag, folks. The first week is a write-off, to be honest. A big storm system is gonna mess things up, with onshore winds, risk of thunderstorms, and lumpy, dangerous surf. We're talkin' a solid 12 ft swell on Saturday the 8th, but it's all onshore junk with a 25 mph wind shredding it. The combined energy is a massive 3510 for that morning, but with conditions like that, it's a hard pass. That poor quality sticks around, with onshore winds and messy seas through the 9th, 10th, and beyond. You're not gonna want to paddle out in this.

Look, we've got a loooong gap here. From Saturday until almost the following Tuesday, it's just no good. But then, things change.

Tuesday, August 11, is our standout. The morning is the real gem. We get a 4 ft easterly swell with a 12-second period. That's a solid groundswell, and the wind goes totally glassy – 3 mph from the NE. That's gonna mean absolute perfection. The combined energy is a solid 877, so there's some push. Udo Shrine will be cleaning up. The afternoon is just as good, with the same glassy conditions from the ESE. This is the window to get out there.

After that, the surf drops off again. Wednesday through to the following Monday, we're lookin' at small, weak swell, mostly under 4 ft, and a lot of onshore wind. It's pretty much a flat spell. The 12th has a clean 4 ft S swell, but the energy is weak at 249. Not enough to get excited about.

Then, on Wednesday, August 19, we get a late call. A new pulse of swell should arrive. Lookin' at 10 ft from the east on the 19th morning, with a 10-second period. The energy is a strong 1561. The wind is onshore, but it's a gentle breeze, which is a lot better than we've had. The optimum swell direction for Udo Shrine is from the south, so this east swell isn't perfect, but it's a big increase. This is one for the experienced crew only, as 10 ft is expert territory. It's a long-range call, so keep an eye on it.

The crowd factor at Udo Shrine is a problem, too. It's listed as "often", so you can expect company, especially on that Tuesday window.

So, to sum it up for you: the first week is a total dog. Surf the morning of Tuesday the 11th for the best clean conditions. Then, hold on for the 19th of August if you're after something bigger. That's the long-range potential.

Rusty, signing off.

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.
