Table - best surf conditions forecast for Udo Shrine over the next 16 days.
Alright, Rusty here again. Let’s break down Udo Shrine. This is a reef break that’s inconsistent and needs a good south pulse to wake up.
The action starts Sunday, July 12th. Water temp is 79°, a bit cooler than usual for this time of year. We’ve got a solid 8ft south swell with a 13-second period—that’s proper groundswell, with combined energy of 2570 (strong). This is expert-only, heavy and powerful. Wind is a light cross-off from the SSE, keeping the surface clean. It’s the standout session, but crowds are “often,” so expect a few out there.
Sunday afternoon drops to 8ft south, 12 seconds, and 1625 energy (still strong). The wind is a moderate cross-off, but conditions are marginal, so the morning is the real deal.
Monday the 13th morning is a beauty. Swell is 5ft from the south, 11 seconds (630 moderate energy), and the wind goes light offshore from the WSW. That’s clean, lined-up reef waves for the intermediate surfer. The afternoon is also clean with a 5ft south swell, but the morning is the winner.
Tuesday the 14th morning goes glassy with a 3ft south swell, 9 seconds, and 175 energy (weak). It’s small and ordinary, but glassy—perfect for a longboard.
From Wednesday the 15th, the swell drops under 3ft and the quality goes south. There’s a long dry spell from Wednesday morning all the way to Thursday the 23rd, with mostly onshore winds and poor surf. There’s a bump on the 18th and 19th with 8ft east swell, but it’s hammered by strong onshore winds—that’s kite-surfing weather, not paddle surfing.
A window opens Friday the 24th morning. The wind goes offshore from the WSW, with a 3ft east swell, 10 seconds, and 204 energy (weak). Conditions look good, but the waves are small. Saturday the 25th morning is glassy with a 2ft east swell. It’s a longboard or groveler game.
The big highlight is Sunday morning, July 12th. That’s the one to chase. The rest of the 16 days is mostly a lull, with a few tiny, clean windows in the second week for the dedicated surfer.
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.
