The Lowdown
Right then, let’s have a look at what’s on the cards for Udo Shrine over the next couple of weeks.
First up, it’s a bit of a frustrating start. The reef here at Udo Shrine is exposed, but the conditions just aren’t playing ball for a proper paddle session. We’ve got a pulse of swell coming in, but the wind is all wrong, and the water’s getting chopped up. For the first few days, it’s looking pretty grim. Sunday the 23rd and Monday the 24th are a write-off with onshore winds and messy surf. The combined swell energy is moderate at 252 and building, but the quality is poor.
Things get a bit wild from Tuesday the 25th through to Thursday the 27th, with a big, strong swell arriving. We’re talking swell heights pushing 15 ft to 16 ft, with a very long period of 16 seconds from the SE. The combined energy is absolutely pumping, hitting 11204 and 13672, which is very strong. However, the wind is howling onshore at 16 to 19 mph, making it a dangerous, blown-out mess. This is strictly for the experts only, and even then, it’s going to be a battle. For most, it’s more of a kite-surfing show than a surf session.
We get a bit of a breather towards the end of the first week. Friday the 28th and Saturday the 29th see the swell drop back to a more manageable 6 ft to 10 ft, but the period drops to 8 or 9 seconds, so it’s a weaker, short-period windswell. The wind is still cross or cross-onshore, keeping the surface lumpy. The energy drops to moderate (691 to 1707).
Now, there is a tiny window that looks like the best bet of the whole forecast. Sunday the 30th of August morning is a standout. The wind goes completely glassy at 0 mph, and the swell is a clean 3 ft from the ESE. The energy is low at 232, but with perfect conditions, those little waves will be clean and fun for a longer board. It’s a small window, but for a surfer who knows the reef, it’ll be the pick.
Monday the 31st morning also has a chance with glassy conditions and a slightly better 4 ft swell from the SE, with a period of 10 seconds giving it a bit more push (energy 477). That could be a nice, clean session before the wind picks up.
After that, the forecast goes a bit sideways again. Tuesday the 1st of September sees the wind come back onshore, and by Wednesday the 2nd, we’re back into strong, messy onshores. Then, from Thursday the 3rd right through to Monday the 7th of September, it’s another big, windy period. We get another massive pulse of swell, with heights over 15 ft and strong energy values (5783 and 4587), but it’s accompanied by strong to near-gale force onshore winds. It’s just going to be a howling, blown-out mess for nearly a week. The only slight glimmer is Monday the 7th morning, where the wind drops to a light 6 mph cross-onshore with a 15 ft swell (energy 4587), which gets a score of 4, suggesting it might be the least worst of that period, but it’s still a long way from perfect.
So, overall, there’s a long gap of poor surf until that glassy Sunday the 30th. That’s your one true standout. After that, it’s a week of wild, windy swell that’s best left to the experts or the kite crew. Keep an eye on the forecast, as things can change, but for now, it’s a waiting game.

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.

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.
