Table - best surf conditions forecast for Udo Shrine over the next 16 days.
Alright mate, let’s talk in feet and degrees now.
We’re looking at Udo Shrine. It’s a reef break that doesn’t pump all the time, so when it does, you gotta be on it. The water is sitting at 26°, which is a touch cooler than average for this time of year, so don’t forget the booties.
Starting Wednesday the 8th, we’ve got a solid groundswell – SE swell pushing 8ft to 8ft, with a long 16 to 17 second period. That’s serious energy (2957 to 3558 on the scale). But the wind is cross-on from the ESE/E, and it’s only “marginal.” It’ll be messy but powerful. Thursday the 9th and Friday the 10th get bigger, with Friday hitting 13ft to 15ft from the SSE, still with that long 17-second interval. Energy jumps to 9389 to 11831, but the wind is onshore from the ENE at 12 mph. At that size – over 8ft – it’s expert-only territory. For most of us, it’s a no-go.
Saturday the 11th drops to 12ft to 13ft from the S, but the wind stays cross-on from the E, keeping it choppy. The first week has no clean windows. The swell dies right off after Monday the 13th, leaving a few days of tiny, poor surf.
Now, the real highlight. Look to Friday the 17th. The morning is glassy – zero wind from the S. The swell is 10ft from the E, with a period of 9 seconds. Energy is at 2241, which is moderate. The call is “excellent surf conditions for experienced surfers.” That’s the one. It’ll be big and clean. Crowds are possible at this inconsistent spot. Monday the 20th brings another spike – 12ft from the ESE with a 16-second period – but the wind is cross-shore, so not as clean.
Tuesday the 21st is just mental – 30ft to 34ft from the E. That’s massive energy (39405 to 53312). The report says it’s too big for the break, so unless you’re on a jet ski, stay on the beach.
So, the best bet is Friday morning the 17th. Glassy, solid 10ft E swell. Everything else in the first week is blown out or too big.

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.

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.
