The Lowdown

G’day, I’m Rusty. Let’s check out the surf for Udo Shrine over the next couple of weeks.

Right, it’s a slow builder here. The first couple of days look clean with glassy conditions, but the swell’s just okay, and then we hit a long run of poor waves. If you’ve got to pick one session, Tuesday morning the 11th is the clear standout.

Tuesday morning the 11th is your best bet. Udo Shrine is a reef break that likes a south swell, but we’ve got an east swell coming in at about 4ft with a 12-second period – proper groundswell that’ll wrap well for the reef. The wind is glassy from the north-northeast at just 3 mph, so it’ll be like butter. The combined wave energy is 739 (moderate), enough to get some decent rides. Water temp is 84°, about average for this time of year, so just a spring suit or even boardshorts. This is the best wave in the whole outlook. It’s inconsistent, so you’ll be waiting between sets, and crowds are a regular thing here, so paddle out early.

Tuesday afternoon the wind swings cross-shore and the swell backs off. Wednesday morning the 12th starts glassy again, but the swell has dropped to 3ft from the south with a 10-second period, and energy is down to 234 – surfable but nothing to get excited about. From Wednesday afternoon the 12th all the way through to early Friday morning the 21st, it’s a long dry spell. Most days have poor surf with small, weak swell and cross or cross-onshore winds. You won’t find a decent wave in that stretch.

Then, Friday the 21st of August brings a second chance. Friday morning has a south swell at 5ft with a 10-second period, and the wind is light cross-offshore from the south-southwest at about 6 mph – clean conditions. Combined energy is up at 542 (moderate), and the reef is open to that south direction. It’s further out in the forecast, so don’t book your flights yet, but it looks promising. The wind gets a bit stronger in the afternoon.

Saturday the 22nd has a glassy morning, but the swell is back down to 3ft, so just small and average. Then we’ve got another flat patch until the end of the window.

Looking at Monday the 25th and Tuesday the 26th, swell jumps big – up to 8ft from the south-southeast with a very long 14-second period, and combined energy hits over 2000 (very strong). But the wind is cross-shore or cross-onshore at 12 to 18 mph, with risk of thunderstorms and rain. That much long-period swell with messy wind will be lumpy and hard to handle – only for experts, and even then, it’s a battle. The long-period groundswell will break fast and straight at a beach, but on a reef like this, it might still have shape – but the wind ruins it. If you kite surf, that setup might be more your thing.

So, bottom line: Tuesday the 11th is the winner – glassy, chest-high groundswell with real quality. Friday the 21st is a good backup for some clean south swell. Otherwise, it’s mostly a waiting game.

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.
