The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Udo Shrine over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. We’ve got tiny waves and a lot of ordinary conditions through the first few days. The real story here is a monster swell that rolls in during the last week of July, but it’s just too big for this spot.
We kick off Friday, the 17th of July, with barely a bump. The morning is cross-off with a tiny 1.0ft SSW swell (18 km/h energy), and it’s just poor. The afternoon goes glassy with a 2ft easterly swell (95 energy), but it’s very ordinary. The weekend stays small, with 2ft easterly swell peaking at 9 seconds. Saturday morning is glassy and clean, and Sunday morning is glassy again, but the waves are just too weak to get excited about. It’s a real waiting game through the 20th, with the same story: small clean waves in the mornings, but nothing with any punch.
Then, on Sunday the 26th of July, we start to see the ocean wake up. The afternoon brings a 5ft SE swell at 13 seconds, but the wind goes cross-onshore with a moderate breeze, and it’s choppy – not for us. The swell energy jumps to 672 (moderate), but the quality is poor.
Monday the 27th of July is where it gets wild. The swell hits 16ft from the SE with a period of 15 seconds, and the energy is a massive 10200 (very strong). But the wind is onshore at 30-35 km/h, and it’s a mess. This is pure power, but it’s not for paddling. This setup looks more interesting for kite surfing than paddle surfing.
The peak of the swell hits Tuesday the 28th of July. We’re looking at a 25ft to 28ft SSE/SE swell with a 15-second period, and the energy is off the charts at 44261 (extremely strong). The wind is a fresh cross-shore, but the wave comment says it's too big for this break. It’s a no-go for anyone but the most experienced, and even then, it’s a pass.
Wednesday the 29th of July sees another 30ft swell from the south, with clean cross-off winds at 40 km/h. Still, the energy is 27882 (extremely strong), and it’s just too much for Udo Shrine. The wave comment confirms it’s too big.
Things finally settle down on Thursday the 30th of July. The morning brings a clean offshore wind from the WSW at 30 km/h, with a 8ft SSW swell at 8 seconds. The energy is 759 (moderate). It’s marginal, but the offshore wind makes it rideable for the experts. By Friday the 31st of July, the swell drops to 3ft from the S, with a moderate offshore wind, and the energy is 210 (moderate). It’s surfable, but very ordinary.
The best of the run comes on Saturday the 1st of August. The morning has a glassy offshore wind, with a 3ft SSW swell at 7 seconds and 212 energy (moderate). The comments say "expect good surf conditions." It’s not huge, but it’s clean and the best option in the whole 16-day window. The water temp is a warm 82°, which is about average for this time of year, so no need for a spring suit.
Overall, it’s a mixed bag. The first week is flat and ordinary, the middle of the window is dangerously big, and the very end offers a small, clean window. The standout is that Saturday morning, the 1st of August, at Udo Shrine. It’s a small, clean session with a light offshore breeze. The break is inconsistent, so don’t expect a packed lineup, but you might have it to yourself.
Rusty.

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.
