The Lowdown
Right, grab a coffee and I’ll talk you through it, because it’s a pretty frustrating run for the most part.
The only option we’ve got on the entire 16-day board is Udo Shrine, and I won’t lie to you – it’s a tough slog. The first week and a half is basically a write-off. From Sunday the 6th right through to Friday the 18th, it’s a relentless block of cross-onshore winds with messy, lumpy surf. The early part of the week has combined swell energy in the 200–340 range, which is weak to moderate, but it doesn’t matter because the wind just ruins it. You’ll be scratching your head at the car park.
The first whiff of something decent doesn't arrive until Wednesday the 9th. For the morning session, the wind goes glassy – absolutely dead calm – and the swell is a clean 4 ft from the ESE with a 10-second period. The combined energy is 249, so it's moderate but not thumping. The water temperature is sitting at 84°F with a normal anomaly for this time of year, so it’s your standard warm tropical dishwater. This is your one standout for the first week, but it’s only a morning window – by the afternoon, a cross-onshore breeze messes it up again.
The second week is a complete mixed bag. The swell actually builds significantly on Tuesday the 15th, with a 8 ft pulse from the east at 10 seconds (combined energy of 1142 – that’s a solid swell event). The wind clocks onshore though, and with that size, it’s only going to be for the experienced crew. The tide may also be a problem. Then on the 16th, conditions are marginal with a light cross-onshore. Nothing really locks in.
Your one real beacon is Saturday the 19th. The morning session sees a light cross-offshore wind, a small but clean 2 ft from the east with a long 13-second period, and combined energy of 201. The wind is glassy-clean. It’s a tiny little window of good surf conditions, but you’ll be on a mal or a longboard because it’s small. The period is long, so expect longer lulls between sets but better shape.
Sunday the 20th morning is also worth a mention – clean, gentle offshore wind from the WSW with 3 ft from the NE, but the period is down to 5 seconds, so it’s weak and crumbly. Just ordinary.
Overall, the best on offer is Wednesday morning the 9th for the glassy, clean conditions, and then Saturday morning the 19th for the clean cross-offshore vibe on a long period swell. Both are tiny in size, so keep expectations low. It’s a frustrating outlook. The reefs need clean wind, and it’s just not cooperating.

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.
