The Lowdown

Alright, surfers, Rusty here. Let’s talk about the waves at Udo Shrine.

To be straight with you, the next week and a half are looking pretty grim. We’ve got a lot of wind, mostly onshore or cross-onshore, and the swell is all over the place with short, weak periods. For the first stretch, through the 18th, there’s just nothing doing. It’s a real flat spell, with the odd pulse of energy that gets chopped up by the breeze. We’re talking poor conditions, messy surfaces, and next to no worthwhile surf. You’d be wasting your time. The water temp is about normal for this time of year, so at least you won’t freeze while you’re getting skunked.

Then we start to see a change. Around the 15th of September, we get a little glimpse of hope. The morning is still no good, but Tuesday afternoon looks like it might clean up. A light offshore drift from the south sets in and the swell is a modest 5ft from the ESE, with a period of 9 seconds. The combined energy is moderate (378), and it’s the first time we get a "clean" read on the conditions. This is the first real window, but it’s not a standout, just a breather.

Now, here’s the one you’ve been waiting for. The real talk is the Monday the 21st of September. We’ve got a serious pulse of long-period groundswell arriving from the ESE, with a period of 18 seconds. This is some proper energy, with the combined swell energy reading a huge 6623 for the morning. The swell is a solid 12ft. This is big, expert-level surf. It’s too big for beginners, and even for most intermediates, this is a beast. If you’re an experienced surfer, this is your window. The wind looks light and cross-shore, which should keep it from being a total washing machine, but at that size, it’s going to be heavy. This is the standout of the whole period.

The energy rolls over into Tuesday the 22nd, with still-strong 10ft surf and a 16-second period, but the wind starts to get a bit more on it. It’s still a solid option for experts, but Monday is the day.

For the rest of the second week, it fades pretty quickly. Wednesday the 23rd brings it down to a more manageable 5ft, but the conditions are just marginal. There’s energy around, but it’s not going to be the clean, firing day we all want.

So, bottom line: suffer through the flat spell, mark your calendar for the 21st, and if you’re not an expert, maybe find something else to do that day. This reef break is inconsistent, so when it does line up, it’s worth the wait.

Rusty, out.

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.
