The Lowdown

Right then, let’s have a look at what’s on the table for Udo Shrine.

Honestly, the next couple of weeks are a bit of a mixed bag. We’ve got a long, frustrating wait for anything worthwhile. The first real surfable window doesn’t show up until the morning of Wednesday the 9th of September, and even then, it’s a struggle. You’ll be looking at small 3ft SE windswell, period a short 8 seconds, and the combined energy is weak (152). The conditions will be glassy, so it’s not a total loss, but it’s really just something to get wet on. For a break that’s inconsistent, you’re relying on a lot of things to line up, and they aren’t.

From there, it’s a long stretch of poor surf. The wind is mostly a cross-onshore breeze, and the swell direction is all over the shop. The energy picks up around the 13th and 14th of September with 3ft to 5ft swell, but the wind is onshore and lumpy, making it a messy, blown-out mess. The combined energy readings hit moderate to strong levels (524 to 621), but that energy is wasted with the wind ruining any shape. Honestly, for a beach setup like this, with that wind and those chop levels, it’d be more interesting for a kite surfer than a paddle surfer.

Now, there are two dates that look like the real standouts. The first is the morning of Wednesday the 16th of September. We get a 4ft E swell with a period of 9 seconds, and it’s glassy. The combined energy is strong (451), and the water is about average for the time of year. This is the pick of the bunch for the whole forecast. It’s clean, it’s got some push, and you’ll have the place to yourself because the crowds are often there, but the long run of poor conditions will have put most people off.

The other one is the morning of Thursday the 17th of September. It’s smaller, 2ft from the E, but with a 12-second period. The energy is moderate (242), but the wind is a light cross-offshore, so it’ll be clean. It’s not a day for big waves, but for a longboard or a funboard, it’ll be a lovely, cruisy session.

The following week, from the 18th, we see a drop-off in quality. The morning of Monday the 21st has glassy conditions with a 4ft E swell, but the period is a short 7 seconds, so it’s weak (160). The afternoon of the 21st looks better with a 5ft E swell and a light offshore wind, so that’s another one to pencil in as promising but less certain.

So, to sum it up: this is a long, slow start. Don’t hold your breath until that Wednesday the 16th of September morning. That’s your best bet. The Thursday the 17th morning is a close second for a clean, small-wave session. Otherwise, it’s a lot of waiting for the wind to play ball.

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.
