Alright folks, Rusty here. Let’s have a look at the coming days.

We’ve got a classic pulse of south swell heading for Udo Shrine, but it’s not a straight-forward call. That big spike of energy is coming Saturday and Sunday, with a huge long-period groundswell from the south. The combined energy is through the roof, a massive 10274 on Saturday morning. But the winds are a real pain in the neck – cross-on and choppy both days. There's a risk of thunderstorms around too. It’s going to be a handful, with 15 ft to 13 ft of swell. With the period hanging at 17 seconds, that’s a very long period groundswell, and for a reef break like Udo Shrine, that can mean some real shifty, powerful lines. Not for beginners at that size – that’s expert territory on Saturday.

The real standout for clean waves looks to be Monday afternoon (July 13th). By then the swell has dropped back to a much friendlier 5.2 ft from the south, still a solid 11-second period, and the winds turn cross-off and light at 9 mph. The combined energy is still a moderate 622, so there’s some push, but the surface is clean. It’s not as big, but it’ll be so much more user-friendly than the weekend chaos. The water temp is about average for the time of year, nothing unusual there.

The forecast is unreliable any further out, but the guide does mention Udo Shrine is a reef break here, often crowded, and it can be inconsistent with the right swell. We lose a lot of the energy after the weekend, dropping right off to tiny, glassy waist-high stuff by Tuesday and Wednesday (July 14-15). The energy falls to numbers like 225 and 94, which is weak. Still, you get some glassy mornings on the 14th and then again on the 17th, but the swell is just too small to get excited about.

For the rest of the outlook, there’s a big blank run. After the 21st, we see a massive spike of poor-quality onshore swell again on the 23rd, with 16 ft and onshore winds gusting 19 mph from the north-northeast. That’ll be a washing machine, not for surfing. The best bet for a decent, rideable wave after that looks to be the clear, glassy morning of Saturday July 25th, with a 3.3 ft south swell and 10-second period. The energy is a moderate 203, and with zero wind, it’ll be clean. It’s a long way off so don’t bank on it, but it’s a glimmer.

That’s the run. The early pulse is the big one, but you’ve got to work for it. The cleanest, most enjoyable session for a regular surfer is Monday afternoon (July 13th). See you out there.

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.
