The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day window is a tough one for Udo Shrine. We’ve got a long, dry patch of nothing but poor surf conditions right through to the end of the first week and beyond. The water’s sitting at 82°, which is bang on average for this time of year, so at least a dip won’t shock you, but there’s barely a wave worth paddling for.
The first real glimpse of anything that might work shows up on Tuesday morning, the 15th of September. It’s still only marginal – a 5ft swell from the ESE with a 9-second period, and the combined energy is moderate at 429. Winds are light and cross-shore, so there’s a tiny window for a surf if you’re desperate and the tide plays nice. But honestly, it’s a 1 out of 10 scenario, and the break is inconsistent anyway, so don’t get your hopes up.
Then the real story comes around Saturday the 19th. A big pulse of swell hits – 10ft to 13ft from the ESE, with periods up to 18 seconds, so it’s proper groundswell. The combined energy jumps to 5242 on Saturday morning and 8792 by the afternoon – that’s strong, powerful energy. But here’s the kicker: the wind is onshore from the ENE at 19 to 22 mph, mushing everything up. The break is a reef, and with that long period, it’ll be breaking straight and fast – only for experts, and even then, it’ll be messy. Sunday the 20th is even bigger, with 16ft swell and 11758 energy, but 25 mph cross-onshore winds just blow it out completely. Too big, too windy, and a recipe for a beating if you’re not a pro.
After that, it drops off fast. Monday the 21st sees near-gale winds at 31 to 34 mph, and the swell plummets to 2ft – total washout. The rest of the forecast is more of the same: tiny, weak swell, cross-onshore breezes, and combined energy values barely cracking 100. The only slightly clean moment is Tuesday afternoon the 22nd, with a cross-offshore wind and 2ft, but it’s too small to ride.
So, what’s the best on offer? If you’re an expert and you don’t mind a battle, the Saturday morning the 19th has the biggest, most powerful swell of the whole period, but it’s for experts only and the wind is against you. Otherwise, there’s nothing to get excited about. This area is known for dry spells like this, so it’s not unusual – just pour a coffee, watch the charts, and wait for the next proper window.
Rusty.

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.
