The Lowdown
Alright, Rusty here. Let's take a look at what we've got for Udo Shrine.
Right off the bat, the early part of the run looks pretty grim. We're looking at a long stretch of poor to marginal conditions. The first few days up to the 14th are a write-off with tiny, weak waves and cross-onshore winds. The water temp is sitting at 82°, which is about average for this time of year.
Monday the 15th of September is where it starts to get interesting. The morning is looking glassy, and the swell is picking up to a clean 5ft from the ESE with a moderate combined energy (460). This is the best on offer in the near term, but it's an inconsistent reef break, and crowds are likely. The period is 10 seconds, which is decent, but nothing too special.
From the 16th through the 18th, the wind swings onshore and the swell drops, so it's back to the poor stuff.
Now, here's a real standout, but you've got to wait for it. Saturday the 19th sees a big pulse of swell, but the wind is a mess. However, on Sunday the 21st of September, the swell is predicted to be huge, with 25ft to 28ft from the ESE. The combined energy is off the charts (20325 to 32055). The wind and tide are favorable for the break, but these waves are massive. This is strictly for experts only, and it's still a long way out, so treat it as promising but less certain. The long period (13 seconds) suggests some serious power, and at a reef break like Udo Shrine, that could mean some proper, heavy barrels. It's too big for anything else.
After that massive swell, it drops back to nothing for the rest of the period. The wind comes up from the SE and SSE, turning messy, and even hitting storm force on the 23rd.
So, to be honest, there's not much to get excited about. The clean glassy window on the 15th is your best bet for a decent paddle, but it's a short-lived window. The big stuff on the 21st is a monster waiting to happen, but only if you've got the skills and the nerve.
Rusty, signing off.

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.
