The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s on offer at Udo Shrine over the next couple of weeks.
First up, the water temperature is running about average for this time of year, so nothing unusual there. The outlook kicks off on Saturday the 18th of July with some small, clean surf. We’re talking tiny 2ft easterly swells, but the wind is glassy in the morning, making it feel like a proper session for the longboard or a fun little foamie. The wave energy is weak (81), so don’t expect much push. It’s surfable, but very ordinary. This pattern of small, glassy mornings with a bit of cross-shore chop in the afternoon sticks around through Monday the 20th, when the swell nudges up to 2ft and the energy gets a little more moderate (106). Still, nothing to write home about. Tuesday the 21st is more of the same.
Then Wednesday the 22nd drops off a cliff – the swell plummets to 0.7ft with next to no energy (6). That’s a dead day. Thursday the 23rd shows a little pulse back to 2ft with moderate energy (117), but still just ordinary conditions.
Friday the 24th brings a real oddity – a 0.7ft swell from the ESE with a very long period of 18 seconds. That’s that long-period groundswell I mentioned, but it’s just too small to do anything with. The energy is low (45). The weekend of the 25th and 26th is a write-off with onshore winds and tiny, weak swell.
Now, the second week gets interesting. From Monday the 27th of July, the swell starts building. By Tuesday the 28th, we’re seeing 8ft to 10ft from the SE with strong wave energy (2077 to 3094), but the wind is howling onshore from the east at 15 mph. The conditions are poor – blown out and messy. This continues through the end of July and into the start of August, with the swell ramping up to a massive 23ft on the 31st, and the combined energy screaming into the tens of thousands. The wind is gale-force, so this is not for paddle surfing – it’s more of a kite situation if anything.
The one standout in the whole 16-day window is the very last session. On Sunday the 2nd of August, the morning brings a solid 16ft swell from the SSE, but here’s the kicker – the wind swings offshore from the west at 22 mph. That’s fresh offshore and clean. The wave energy is still strong (7084), but the swell is way too big, even for confident intermediates. It’s an expert-only window at Udo Shrine, and honestly, that size on a reef is heavy. Crowds are often a factor here, but with the size, you’ll only have the brave ones out. The tide and wind look favorable, but the swell is predicted to be too big for this break. It’s a proper, serious, big-wave day.
Overall, the first week is small, clean, and very ordinary. The second week has huge swell but terrible wind until that final Sunday morning. There’s a gap of no real recommendations from the 22nd through to the 27th, and then it’s a wild ride. The best of the lot? That Sunday the 2nd of August morning, if you’re an expert and you’ve got the nerve. Otherwise, it’s a lean run.
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.
