The Lowdown

Alright, Rusty here again. Let’s break down the same forecast for Udo Shrine in feet and miles per hour.

Right off the bat, I gotta be straight with you – it’s a tough start. The first few days are looking pretty weak. We’re dealing with tiny, mostly east-southeast swells that are barely pushing 2ft to 3ft. The combined swell energy is low, mostly sitting in the double digits (84 to 156), which means there’s just no power in the water. The water’s at a warm 83°F, which is bang on average for this time of year, so at least you won’t need a thick suit.

Tuesday 21st is a write-off. Clear skies, but a 12 mph south wind is cross-off, and the waves are a sad 2ft from the east with a short 9-second period. If you’re paddling out, you’re doing it for the tan, not the surf.

Wednesday 22nd morning is the first real glimmer. A tiny 3ft east swell but with a 11-second period and glassy conditions – that’s a “Slight air” wind. It’s surfable, but it’s very ordinary. The swell energy is moderate (156), but the size is just too small to get excited about.

Thursday 23rd morning is similar: glassy, 2ft, period up to 10 seconds. It’s clean, but you’ll be scratching for anything with a face. By the afternoon, the south wind picks up to 9 mph cross-off, and it’s a no-go.

Friday 24th and Saturday 25th are tiny. We’re talking 0.7ft to 1ft swells. Forget it.

Sunday 26th morning gives us another tiny window: 2ft from the south, glassy. Again, it’s clean but insignificant.

Monday 27th morning and Tuesday 28th morning are the same story – glassy, 2ft to 2ft, but the swell is short and weak. The energy bumps up to 153 on Monday morning, but it’s just not enough to call it good.

Wednesday 29th and Thursday 30th mornings are the same pattern: small, glassy, but ultimately forgettable.

Now, here’s where it gets interesting. Friday 1st August is a storm warning. We’ve got a risk of thunderstorms and a 19 mph onshore wind. The swell jumps to 5ft from the southeast with a 13-second period, and the energy is 963 – that’s a serious ramp-up. But it’s a complete mess. The wind is lumpy, and it’s cross-onshore. This is more of a kite-surfing day than a paddle-surfing day.

Saturday 2nd August is the standout. The swell is 8ft to 10ft from the southeast with a 14-second period. The combined energy is massive (2689 to 3146). The wind is cross-off from the south, so the surface will be clean. However, this is big. Over 8ft, it’s for experts only. This is a groundswell, and with that long period, it’s going to be powerful and straight at a beach break. Udo Shrine is a reef, so it should handle it better than a sandbar, but the direction is southeast, and the optimum swell direction here is south. It’s not a perfect match, but the size and power will make for some serious, heavy waves. This is your best shot, but only if you’ve got the skills.

Sunday 3rd August is even bigger – 12ft to 16ft – but cross-onshore winds and fresh chop ruin it. The energy is off the charts (5719 to 11185), but you can’t surf it. It’s dangerous and messy.

Monday 4th and Tuesday 5th August are a washout. Strong onshore winds, 16ft+ swell, and total chaos. This is a big, stormy mess.

So, what’s the call? The first week is a dead loss. The only real hope is Saturday 2nd August morning and afternoon, when the big south groundswell meets clean cross-off wind. It’s a big, expert-only groundswell that will be heavy and powerful on the reef. It’s a promising window, but it’s a long way out, so keep an eye on it. The rest of the solid swell is just blown out.

Rusty.

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.
