Alright, let’s talk about Udo Shrine. This is a reef setup that’s inconsistent and can get crowded. The best swell direction is from the south, but the early part of the week is all small and ordinary. There’s a gap of a few days with not much to get excited about, but things start looking up later.
Right now, on Sunday the 5th, we’ve got tiny 1ft waves from the ESE at 9 seconds. The water’s sitting at 79°, which is a bit colder than normal for this time of year—down about 2°. Wind is light offshore from the west, so it’s clean, but there’s just no energy. Combined swell energy is only 36, so it’s weak. Not worth paddling out yet.
Monday the 6th is more of the same—1ft, very ordinary, even with a bit more period. The combined energy climbs to 158 Monday morning, but conditions are still just marginal. You could surf, but it won’t be memorable.
Now, Tuesday the 7th is where it gets interesting. Morning brings a clean 5ft SE swell with a 14-second period—that’s a proper groundswell. The wind is dead calm, glassy as it gets. Combined energy jumps to 685, moderate. The swell direction is from the southeast, which isn’t the optimum south, but it’s close. The 5ft height is good for intermediates, not too big. Just know that longer-period swells like this can break a bit straight at beach breaks, but on a reef like Udo Shrine, it should set up nicely. Crowds are often here, so expect company.
Tuesday afternoon stays 5ft from SE at 16 seconds, but a light cross-onshore breeze kicks in, putting a few ripples on the surface. Still surfable.
Wednesday the 8th sees the swell building. Morning has 8ft SE at 18 seconds—that’s a solid groundswell, with combined energy of 3993, strong. Wind is onshore from the NE, so it’s going to be messy. By afternoon, it’s 10ft from SE at 17 seconds, energy 5428, but onshore wind kills quality. This is getting big—over 8ft, so really just for experts. Not ideal conditions.
Thursday the 9th peaks around 12ft SE at 16 seconds early, energy 6206, but onshore ENE wind at 12 mph keeps it rough. By afternoon, direction shifts to SSE with the same height, but wind picks up to 16 mph and it’s even worse. For paddle surfing, this is looking rough—maybe more of a kite day.
Friday the 10th brings the biggest swell of the run: 15ft SSE at 17-18 seconds, energy over 10,000. That’s very strong. But with onshore and cross-onshore winds, plus risk of thunderstorms, conditions are poor to marginal. Huge and messy—only for the hardcore, if anyone’s out.
The weekend of the 11th and 12th starts dropping: 12ft Saturday easing to 7ft Sunday, but wind stays onshore or cross-onshore, with heavy rain possible. Quality remains low.
From Monday the 13th onward, the swell fades fast—back to 5ft or less, short periods, onshore winds. Combined energy drops below 500. The rest of the forecast through to July 20th looks poor. A few small clean windows on the 19th with 1ft SSW swell and offshore wind, but it’s weak.
So, if you’re looking for the standout, Tuesday the 7th morning is your best bet—clean, glassy 5ft SE groundswell at Udo Shrine. That’s the one to aim for. The big stuff midweek is too messy and big for fun. After that, it’s a long stretch of flat or poor conditions.

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.
