The Lowdown
Alright, Rusty here. Let’s talk about the next couple of weeks at Udo Shrine. It’s a reef break that likes a south swell, but the wave window is going to be a real mixed bag for a while.
We’re staring down a long, flat spell to start things off. From now through the 26th July, the surf is pretty underwhelming. We’re looking at small waves, mostly in that 2 ft to 3 ft range, with short periods around 9 seconds. There’s not enough energy to get excited about. The combined energy on the 18th is only 85, which is weak energy. The water temp sits at 28°, which is just about average for this time of year. The real silver lining is the wind. Mornings in particular are glassy and clean. On the 20th, you’ve got a glassy dawn with a 2 ft east swell and a period of 10 seconds, giving it a combined energy of 103. That makes it the best of a bad bunch for a beginner session: small, clean, and easy. You’ll be sharing it with others though; crowds are likely here.
Things go totally flat during the 24th–26th, so just put the board away for a few days.
Then we hit the 27th. A new SSE groundswell arrives, with a very long period of 17 seconds pushing the swell to 3 ft by Monday morning, but the wind turns onshore from the NE at 9 mph. The combined energy jumps to 772 (moderate), but the conditions go marginal. By afternoon, the swell is 6 ft, combined energy shoots up to 1883 (strong), but it’s cross-onshore at 12 mph and choppy. This is not the setup to paddle out for a fun session. It could be more interesting for a kite surfer than a paddle surfer.
The 28th gets blown out entirely. We’re talking 10 ft to 13 ft of ESE swell with 18 mph+ onshore winds, thunderstorms, and a combined energy up to 9951. That’s very strong energy, and the sea state will be dangerous. The 29th is even bigger: 20 ft to 21 ft swell with 28-31 mph winds. The combined energy peaks at 22511. Way too big for this break. Leave it for the experts only, if anyone is crazy enough. The wind on the 29th is a near-gale cross-onshore; it’s going to be blown out. No good here.
The 30th and 31st drop off rapidly in size as the wind swings around. The 31st morning has a 2 ft S swell with a 40+ mph gale blowing cross-offshore, keeping it clean but the swell is tiny. By the afternoon, a strong offshore WSW wind kicks in at 28 mph making it clean but hard to paddle into. Combined energy is 132 (moderate).
Now, finally, a real standout arrives at long range. The 1st and 2nd of August. This is your window. On the 1st afternoon, expect a solid 4 ft south swell at 9 seconds with offshore winds from the WSW at 16 mph. That’s a moderate offshore and clean setup with a combined energy of 320. The 2nd is just as promising: 3 ft south swell, morning offshore breeze at 9 mph, glassy, with a combined energy of 256. This is the best we’re going to see. Clean, rideable, and it matches the optimum swell direction from the south. It’s two weeks out, so it’s promising but less certain.
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.
