The Lowdown

Alright, paddlin' out with the Udo Shrine charts here, and I'm not gonna sugarcoat it – it's gonna be a long wait for anything decent. This reef break is known for being inconsistent, and this run is really testin' that.

The general pattern for the first week-plus is a whole lot of nothin'. We got a bunch of onshore and cross-onshore winds, mostly light breezes, but it's enough to keep the surface all chopped up and nasty. There's a bit of swell from the east-southeast, but the quality is just poor. The energy is weak to moderate most days.

There's a massive dry spell here. From the 11th all the way through the 17th of September, there ain't a single session worth considerin'. All poor surf. A full week of skunked.

Things get interesting around the 18th of September, but not in a good way. Friday afternoon the 18th, a 1.6m swell from the ESE shows up with a very long 17-second period. The combined energy jumps to 1521 (strong). That's a serious groundswell for a reef, but the wind is blowin' onshore. It's gonna be sloppy.

Then it gets proper heavy. Saturday the 19th of September is a 5.5m swell from the ESE, with a combined energy of 14213 (very strong). Sunday the 20th is similar size but from the SE, energy at 15126. Monday the 21st of September is just apocalyptic – an 11m to 12.5m swell from the SE and SSE, with energy readings over 50,000. That's a staggering amount of power. The charts say wind and tide are favorable, but for any normal surfer, that size is a straight-up danger zone at this break. This is only for the absolute bravest and most experienced. For everyone else, it's a hard pass.

After that big pulse, the swell fades but the wind stays a problem until the 24th of September, Thursday. That morning, we finally get a clean offshore wind from the WSW at 30 km/h, droppin' to 25 km/h in the afternoon. The swell is tiny, only 0.5m to 1m, from the NE with a weak, short period. The energy is a low 107. It'll be glassy and clean, but you'll be on a longboard just prayin' for a ripple.

The best shot comes Friday the 25th of September morning. A 2.1m swell from the ESE with a 16-second period – that's a beautiful, long groundswell perfect for a reef. The combined energy is 2142 (strong). The wind is a light cross-onshore from the NNE. It's not perfect, but it's the cleanest and most powerful wave in the whole window. The optimum swell direction for the spot is from the south, so this ESE swell is a little off-angle, which is why it's only a marginal call.

So, lookin' at the full 16 days, the one to maybe circle is Friday the 25th of September. That 2.1m groundswell from the ESE at Udo Shrine is the standout, but the light cross-onshore keeps it from being a true classic. The water temp was around 28° earlier on, which is right about where it should be for the time of year.

Other than that, it's a whole lot of waitin', a monster swell you'll probably want to watch from the cliffs, and then a fade-out. Not the most action-packed outlook.

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.

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.
