The Lowdown
Alright, grab a coffee, because this 16-day window for Udo Shrine is a tough one to get excited about. This is a classic case of a reef that rarely fires, and when it does, conditions fight you. The whole period is a bit of a grind, with no real standouts. Let's break it down.
The first decent shot comes Sunday morning, July 19 – glassy, clean, with a tiny 2ft easterly swell. The combined energy is weak (70), and the period is a mediocre 9 seconds. It's surfable, but honestly, it's the kind of wave that gets you wet without much reward. The same goes for the glassy mornings on July 20 (2.3ft, 103 energy) and July 21 (2.3ft, 86 energy). The wind is dead calm or light offshores, but the swell is small, the direction is from the east, not the south that this reef really wants, and the break is inconsistent. Crowds are likely, so you'll be sharing those little bumps.
Wednesday morning, July 22, offers a slight bump – 2.6ft from the east, period 11 seconds, energy 156. Still glassy. That's probably the best of the first week, but it's still a very ordinary wave. Don't expect any hollow sections.
Then the forecast gets weird. Thursday and Friday, July 24-25, the swell drops to 0.7-1.3ft, but with a long 18-second period groundswell. That's a tease – long period and small size means barely any push. The wind is light cross-shore, so it's just messy.
The big change comes on Monday, July 27. The swell jumps to 6.2ft from the southeast, period 15 seconds, and the combined energy skyrockets to 1709. That's a serious groundswell. But the wind is cross-onshore, and the forecast says "marginal surf or questionable tide." This is a reef, so a long-period swell from the southeast could work, but the onshore wind will chop it up. It's

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.
