The Lowdown
G’day, Rusty here. Look, I’ll level with you – the next two weeks at Udo Shrine are mostly a write-off. A whole heap of wind, cross-onshore slop, and poor conditions dominate the outlook. It’s not until the final two days we get a proper taste of something special. The water temp is sitting around 84° with a slight positive anomaly, so about average for this time of year.
The first week is grim. Tuesday the 1st kicks off with a small 4 ft SSE swell at 8 seconds with a gentle cross-onshore breeze – just choppy junk. Combined wave energy is weak (231). It stays poor right through to Monday the 7th, with the swell fluctuating between 1 ft and a messy 8 ft, but always battling strong to fresh cross-onshore winds. Even when an 8 ft pulse hits on Friday the 4th, it’s wind-ruined.
The second week starts no better. From Tuesday the 8th through to Monday the 14th, the swell picks up but so does the wind – cross-onshore and fresh to strong, with combined energy climbing into the 1000s, but the conditions are lumpy and messy. The 12th offers a marginal moment with 6 ft ESE swell and moderate cross-onshore chop, but it’s not worth paddling out for.
Then everything changes. Tuesday the 15th morning is the standout – glassy, dead calm, with a solid 12 ft swell from the east at a long 15 seconds. Combined energy is massive at 6114. This is groundswell with serious grunt, perfect for a reef like this, but at 12 ft, it’s strictly for experts. Big, long-period sets will groom nicely over the reef. The water is glassy. It’s the best on offer by a mile.
Tuesday afternoon stays clean with a light cross-offshore breeze and 12 ft swell (4389 energy). Still only for the experienced crew. Wednesday the 16th morning backs off to 5 ft but with a long 15-second period and glassy conditions – excellent for experienced surfers (2067 energy). Afternoon sees the period stretch to 17 seconds and 7 ft, but a light cross-onshore ripple creeps in, so it’s a bit touchy on the tide.
Summing it up: the only two days worth your time are Tuesday the 15th and Wednesday the 16th. That Tuesday morning is the absolute pick – big, clean, and pumping. Everything before that is a blown-out mess. Rusty out.

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.
