The Lowdown

Alright, let’s be straight with you. The next couple of days at Udo Shrine are pretty much a write-off. We’ve got some junk wind and tiny, weak swell, so don’t even think about paddling out yet. Wednesday morning has a bit of east swell at 4 feet, but that northeast cross-onshore breeze is chopping it all up. The energy is weak at 449, and it just doesn’t have any push.

That poor run carries right through Thursday and Friday. We’re talking ankle-biters, 2 feet or less, with onshore winds and a bit of rain around. It’s flat, it’s messy, and honestly, you’re better off doing anything else.

Now, here’s where it gets interesting. The weekend starts to show some signs of life but it’s still not clean. Saturday the 19th has a bump in size – 10 feet by the afternoon – but that northeast cross-onshore wind is still messing with it, and the energy jumps up to 3458, which is moderate to strong. It’s got some push, but the surface is going to be rough. Not the one.

Sunday the 20th is the first real standout. The wind drops right out – glassy conditions, both morning and afternoon. The swell holds at 10 feet from the east, with a 12-second period. The energy is strong at 2772. This is real, clean, powerful surf. For experienced surfers only – this is not a beginner wave. The water temp is 82°, which is right on average for this time of year, so nothing unusual there. This is the pick of the first week, no doubt.

Monday the 21st is still okay, especially the afternoon. The swell drops to 5 feet but it’s glassy with an 11-second period. It’s a bit weaker energy-wise at 568, but it’ll be clean and fun for the better surfers. The morning is a bit cross-on with 8 feet, so it’s a bit more challenging.

Then we hit another flat spell. Tuesday the 22nd through to Friday the 25th is basically nothing. We’re talking 1 to 3 feet of weak, short-period junk. The energy is in the low double digits, sometimes triple, but it’s all mush. Poor conditions, poor winds. This is a dead stretch, a good week to get other things sorted.

Now, hold on, because the end of the window is where the real magic is. Saturday the 26th sees the swell start to build again – 8 feet in the morning from the southeast, jumping to 10 feet by the afternoon. The morning is glassy and clean with strong energy at 2736. Excellent conditions for experienced surfers. The afternoon gets a light cross-shore wind, so it’s not as perfect, but it’s still pumping.

Sunday the 27th is big. The swell is pushing 11 to 13 feet from the SSE, with a 14 to 15-second period. The energy is massive – 5239 in the morning, jumping to 6949 in the afternoon. But the winds are onshore or cross-onshore, which is going to put some chop on it. It’s powerful, but it’s not clean. Only for the experienced, and even then, it might be a handful.

Monday the 28th is the absolute standout of the entire forecast. The morning is glassy, with a massive 20 feet of swell from the SSE with a 15-second period. The energy is enormous at 14965. This is a once-in-a-while type of day. It’s perfect, powerful, and clean. Expert only. The afternoon gets bigger – 23 feet – but the wind swings to a cross-off and there’s a risk of thunderstorms. The energy is 21507, which is just insane. It’s too big for most, but for the elite, this is the day.

Tuesday the 29th is still big – 16 feet in the morning with a light offshore wind. Clean, powerful, and the energy is still strong at 7186. Another expert-only day. The afternoon eases to 10 feet, but the wind picks up a bit, making it more marginal.

After that, the swell fades fast. Wednesday the 30th and Thursday the 1st of October are back to small, weak, and poor. It’s done.

So, in short: the first week is a washout until Sunday the 20th. Then there’s a long flat spell. The real gold is at the end – Sunday the 28th is the day to circle, with Monday the 29th as a solid backup. These are big, powerful, glassy swells, so you need to know what you’re doing. Don’t bring the beginners.

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.
