The Lowdown
Alright, Rusty here. Let's get into it. We're looking at Udo Shrine, and honestly, it's a tough stretch ahead. There's a massive swell event hitting right out of the gate on Friday, the 7th of August, but it's way too much for this spot. We're talking a 23ft SE swell with a solid 14-second period, packing some serious energy (17299). That's expert-level stuff, and with a near gale-force easterly wind blowing 31 mph straight onshore, it's going to be a complete mess. The water is warm, sitting at 84°, which is pretty normal for this time of year.
The first real chance to even think about a paddle is Monday morning, the 10th of August. The swell drops to a still-chunky 6ft from the east, but that wind is still howling straight onshore at 12 mph. The combined energy is still moderate (1707), but the conditions are only marginal at best. It's not going to be pretty.
Things start to get a little more interesting around Tuesday, the 11th of August. The swell eases to 5ft, swinging around to the south with a nice 11-second period, and the wind drops to a light 6 mph from the NE, staying onshore. The wave energy (866) is still moderate. It's still a bit of a fight against the onshore breeze, but the smaller size makes it more manageable. Wednesday the 12th is similar, with a 4ft south swell, but the wind goes cross-onshore.
From the 13th of August onward, it's pretty flat for a long stretch. Swell sizes drop below 3ft and the energy readings are weak, staying under 200 for most of it. There's a few days there with no real surf to speak of.
Looking out to the second week, there's a glimmer on the 17th of August (Monday). A 5ft SE swell rolls in with moderate energy (687), but it's once again plagued by a moderate cross-onshore breeze at 12 mph, making for a choppy surface. It's a far cry from clean. The best bet in the whole run is probably the morning of Tuesday the 11th, with the 5ft south swell and lighter winds, but even that is an onshore wind and just a marginal call. There's no standout day here, just a few windows where you might find a rideable, if messy, wave.
It's going to be a long wait for clean conditions at Udo Shrine. Hang in 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. 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.
