The Lowdown

Right, folks, Rusty here. Let's have a look at what's cookin' at Udo Shrine.

We're starting off with a bit of a mixed bag. The water's sitting at a pretty warm 84°F, which is about what you'd expect for this time of year, so no need to dig out the steamer just yet.

The first few days are a bit of a write-off, to be honest. Thursday the 27th has some swell, around 7ft from the SSE, but the wind is a cross-off and there's a risk of thunderstorms. The energy's moderate (732), but the quality just isn't there for a good session. We see a similar story carry through Friday and into the weekend, with smaller swell and mostly onshore or cross-shore winds. Saturday morning the 29th has a moment of calm, glassy conditions with a 2ft easterly swell, but it's just too small to get excited about.

The middle of the week is a no-go zone. From Monday the 31st through to Thursday the 3rd of September, the swell builds, but it's all accompanied by strong, messy onshore winds blowing from the east and southeast. The energy gets up there – 1494 and 1513 – but it's just a lumpy, choppy mess. Not for paddling, that's for sure. The setup looks more interesting for kite surfing than paddle surfing during that stretch.

Now, we do have a couple of windows that look promising. Friday the 4th of September sees a 8ft easterly swell (1735 energy) with a light cross-shore wind, which cleans things up a bit. It's still a little raw, but it's a step in the right direction.

And then, hold onto your board, because the real standout is on Wednesday the 9th of September. The morning is showing a massive 13ft groundswell from the south, with a very long period of 13 seconds. The energy is off the charts at 10324, and the wind is glassy calm. This is exceptional surf, but let's be clear: at 13ft, this is for experts only. It's going to be a beast. The afternoon stays clean with a cross-off breeze, but it's still a 13ft wall of water. The swell direction is south, which is not the optimum direction for this spot (it prefers S), but with that kind of power and that long period, it's going to be a heavy, straight-breaking wave at this beach-reef setup. The long period means it'll be a bit more challenging to paddle out, but the sets will be well-spaced.

The following day, Thursday the 10th of September, is even bigger – a 30ft swell from the southeast with a 14-second period. The wind is clean, but the forecast is clear: the swell is predicted to be too big for this break. A 30ft wave is a monster, and even for the experts, it's likely a paddle-out only for the truly insane.

Things settle down after that. Friday the 11th of September has a much smaller, more manageable 5ft SSE swell with glassy conditions, offering a good chance for a clean, fun session. The energy is a modest 330.

So, the best on offer is without a doubt the morning of the 9th of September for the big-wave chargers, but it's a long way off and the forecast could change. For the rest of us, the 11th looks like the most realistic window for a clean, fun surf.

Rusty out.

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.
