Table - best surf conditions forecast for Udo Shrine over the next 16 days.
The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Right now, things are pretty quiet. We’ve got a small window of surfable but very ordinary waves starting Monday morning, but honestly, nothing to get excited about. The first few days are tiny, with weak, short-period energy, and the wind is all over the place. The best of the early stuff is Wednesday morning at the Udo Shrine (reef). We’ve got glassy conditions, a 2.6ft swell from the east with a 11-second period, and the combined energy is moderate at 156. It’s surfable, but it’s not going to blow your mind. The water temp is about average for the time of year, so no surprises there.
There’s a real gap from Thursday until Sunday afternoon. Sunday afternoon sees a bit of a pulse – a 3.0ft south-east swell, 12-second period, and clean conditions with a cross-off breeze. The energy jumps to 238, which is a solid step up. Still, it’s not a stand-out.
Now, the real standout arrives on Monday 27 July. Monday morning at Udo Shrine is where it’s at. We’ve got a 6.6ft swell from the south-southeast, with a 12-second period, and the combined energy is a strong 1122. The wind is light and cross-off, so it’s clean. This is excellent surf, but at 6.6ft, it’s solid – for experienced surfers only. The break is inconsistent, so you’ll have to wait for sets, but when they come, they’ll be worth it. Crowds are often here, so expect company.
The second week gets wild, but it’s not for the faint-hearted. From Tuesday 28 July through to Sunday 3 August, the swell is massive – 11.5ft to 27.9ft – but the wind is howling onshore or cross-onshore, with gale-force gusts. The energy readings are huge (over 4000, and up to 24,000), but the conditions are blown out. This setup is more interesting for kite surfing than paddle surfing. The reef will be a washing machine. Only the most experienced and suicidal should even think about it.
Finally, on Tuesday 4 August, there’s a cleaner window. A 7.9ft east swell with a very long 18-second period, light cross-off wind, and a combined energy of 5630. The period is so long that at a beach break, it might break too straight, but here at the reef, it could be a gem. This is exceptional for experts, but it’s a long way off, so keep an eye on it.
Overall, the best bet is Monday 27 July morning for the clean, solid swell. The rest is either too small, too windy, or too big.

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.
