The Lowdown

Alright folks, Rusty here. Let's take a look at what's on the menu for the Udo Shrine area. This is a reef setup that's a bit finicky – it's inconsistent, so it doesn't always fire, and when it's good, you can expect company 'cause it gets crowded. Still, when it lines up, it can be a gem.

Right now, the water temp is about average for the time of year, nothing unusual there.

The next couple of weeks are a mixed bag. We've got a long stretch of poor conditions ahead. From Thursday morning (August 13th) all the way through to the end of the following week, most sessions are a write-off. The swell is around 2 to 5 feet, mostly from the SE or E, with short periods around 8-10 seconds, but the wind is a constant problem. It's mostly cross-on or onshore, and often gusty, making the surface choppy. The combined swell energy is generally weak to moderate, sitting between 73 and 400 (moderate wave energy). There are a few windows with glassy or clean conditions, like Thursday morning (Aug 13th) with 2ft S swell at 9 seconds and 166 (weak wave energy), but the score is low. It stays poor for days.

We skip ahead to Friday, August 21st, and things start to shift. That morning, we get a clean, cross-off wind with a 4ft SSE swell at 8 seconds. The energy is moderate at 280. That afternoon, the swell pushes to 5ft from the SSE with a 10-second period, and the energy jumps to 561 (strong wave energy). It's still clean. This is a solid window.

Then, Saturday morning, August 22nd, is the real standout. The wind goes glassy, dead calm, with a 4ft S swell at 9 seconds, energy at 257 (moderate wave energy). That's clean, lined-up reef surf. It's the best of the entire forecast. The crowd factor will be there, but that's the price for a wave like this.

After that, it's back to onshore junk for a few days, with small swell and poor conditions. Then, looking way out to Tuesday, August 25th, we get a big pulse of swell – 8ft from the SE, with a long 14-second period, and energy is a massive 2590 (very strong wave energy). That's a lot of water, but the wind is cross-on at 12 mph, so it's lumpy. That size is expert-only territory, and with the wind, it could be a beast. It's more of a watch-and-see situation from a distance.

The rest of the month trends poor again, with small, messy surf.

So, if you're looking to paddle out, your best bet is the glassy Saturday morning, August 22nd, at Udo Shrine. The Friday before that is also a clean option. The big swell on the 25th is for experienced chargers only, and it's a long way off, so keep an eye on it.

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.
