The Lowdown
Alright, Rusty here. Let’s break this down.
Look, you’re not gonna have much to get excited about for a while. First decent surf isn’t until the 11th, and it’s a short window. That Tuesday morning on the 11th is your one shot: a 4.3ft east swell with a 12-second period, and the wind is dead glassy, calm as can be. The combined energy is moderate (734). That’s the cleanest it’ll be. Water’s 84.2°, which is pretty average for the season. Just keep in mind this spot doesn’t fire often and tends to get crowded.
After that morning, it’s a rough slide. The swell shrinks and the wind goes onshore or cross-onshore, making for poor, choppy conditions all the way to the 24th. There’s a small bump on the 20th with a 5.6ft east swell, but the wind is on your face, and it’s only considered marginal. The energy is moderate (485), but the quality just isn’t there. After that, it’s more of the same – small, weak, and messy. Honestly, for the rest of the 16 days, it’s looking more like a kiteboarding wind-chopper scene than a surf spot.
So, here’s the deal: if you can, hit it Tuesday the 11th first light. Otherwise, you’re looking at a long, quiet wait.

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.
