The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Udo Shrine and, honestly, it’s a bit of a lean spell to start. We’re looking at a long stretch of nothing much worth paddling out for until we get deep into the second week, so don’t rush to wax up just yet.
The first real sign of life doesn’t show until Wednesday, September 9th. That morning, we get a clean 4ft SE swell rolling in with a light offshore breeze from the WSW. The water temp’s sitting around 84°, which is about average for this time of year, so no surprises there. The combined energy is a moderate 249, and while it’s not huge, that offshore wind will have it looking tidy. Just be aware, Udo Shrine is an inconsistent reef break and crowds are often a thing here, so you might have some company for the few waves that come through.
The real standout window, and the one to circle on the calendar, comes on Thursday, September 17th. Thursday afternoon sees a clean 5ft S swell, again with a light offshore from the WSW. The energy jumps up to a strong 747, and the conditions are dialled. It’s not huge, but it’s set up perfectly. The day after, Friday the 18th, is the absolute pick of the entire outlook. We’ve got a glassy 5ft E swell in the morning, with the combined energy sitting at a solid 553. Then, in the afternoon, it really fires up: glassy conditions again with an 8ft SE swell, pushing the energy to a very strong 1271. The forecast says excellent surf for experienced surfers, and I’d back that call. It’s a fair step up in size, so if you’re not feeling confident on a bigger board, maybe sit this one out. For the crew who can handle it, that afternoon session looks like the best wave of the whole run.
In between, there’s a lot of wind and rain to deal with, and a few marginal moments with questionable tides, but nothing worth chasing. Don’t bother with the first ten days; it’s mostly blown out, cross-onshore junk. Save your energy for that window around the 17th and 18th.

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.
