The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid 16-day window ahead, but it’s a bit of a wild one. The first few days are a write-off with the wind, then we get a massive spike that’s way too big for this spot, before it finally settles into something a little more manageable. There’s a promising window right at the end, but it’s a long way off.

The only spot on the radar is Udo Shrine, a reef break that’s inconsistent and can get crowded. It’s exposed, and it likes the swell from the south. The water temp is sitting at 85°F, which is dead average for this time of year, so nothing to worry about there.

Monday the 3rd is a no-go. We’ve got a 5 ft swell from the ESE, period a solid 16 seconds, so there’s plenty of energy (1345), but the wind is cross-on from the NNE at 12 mph, making it choppy and messy. The afternoon is worse. Tuesday the 4th is still a write-off, with the swell jumping to 8 ft but the wind staying onshore and strong. Wednesday the 5th is a monster – 16 ft to 18 ft of east swell, with a massive 17-second period and energy readings off the charts (13439 to 19335). That’s expert-only territory, and even then, the wind is howling at 22 mph. It’s honestly more a kiteboarding setup than a paddle surf one.

Thursday the 6th and Friday the 7th are just silly. We’re talking 26 ft to 28 ft of swell, with near-gale force winds. The combined energy is hitting 43197, which is just insane. Unless you’ve got a tow-in crew and a death wish, stay away. The weekend of the 8th and 9th is still blown out with strong onshore winds and dropping swell, but still far too big for anything clean.

The whole first week is a total loss. The wind never lets up, and the swell is either too small with bad wind or dangerously oversized. From the 10th to the 16th, the swell drops, but the wind stays onshore and messy, keeping the quality low. The 12th and 13th offer a slight glimmer with smaller 5 ft to 6 ft swell and lighter winds, but it’s still cross-on and fairly choppy, so it’s only a marginal call.

Now, the standout. It’s all the way on Monday the 17th of August. The morning shows a 16 ft swell from the east, with a 13-second period and a massive 15701 energy reading. The wind is cross-on from the NNE at 12 mph, which isn’t perfect, but it’s manageable. The afternoon looks even better, with the wind shifting onshore but lighter at 9 mph from the ENE, and the swell holding at 16 ft. The system says it’s too big for the break, but for the right crew on a big-wave morning, that’s a serious session. Tuesday the 18th still has good size at 13 ft, with lighter cross-on winds, but it’s a step down in quality.

So, to sum it up: the first week is a complete right-off. The second week has a few marginal days, but the real target is Monday the 17th of August. That’s a big, powerful swell at Udo Shrine, and if the wind plays ball, it could be a cracker. It’s a long way off, so keep an eye on the charts, but that’s the one to circle.

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.
