The Lowdown
Alright, this is Rusty talkin’. Let’s be straight with you—this isn’t exactly a week of straight-up pumping surf. The first ten days or so are pretty slim pickings. We’re looking at a long stretch of small, weak, and messy conditions before things finally get interesting around the second week of August.
For the first few days, from the 26th of July through the start of August, it’s mostly tiny waves and crummy wind. The swell is barely breathing, with combined energy sitting in the weak range (91 to 124). You’ll see a few mornings with glassy conditions, but the swell is just too small to get excited about—1 ft to 2 ft. The water temp is a warm 84°, which is about normal for this time of year, so you won’t need a thick suit, but you *will* need patience.
There’s a real gap of several days with no real recommendation. From the 26th through to the 2nd of August, it’s basically a write-off for decent surf. The wind is variable, mostly cross or cross-on, and the swell is anemic.
Now, things start to change around the 3rd of August. A long-period groundswell starts to build from the ESE, with periods climbing to 14-15 seconds. The energy jumps into the moderate range (633) and the wave height starts to get a little more interesting—4 ft to 5 ft. But the wind is still cross-on, so it’s not perfect. It’s a step up, but still not the standout.
The real standout window is the 6th and 7th of August. On the 6th, Thursday morning, we’ve got a solid 11 ft swell from the E with a period of 17 seconds, and combined energy is a strong 6149. By the afternoon, it pushes to 13 ft from the ESE with an 18-second period and energy up to 9055. That’s serious groundswell. The wind is light cross-on, so it’s not glassy, but it’s manageable. This is expert-level size—over 8 ft—so if you’re a beginner, stay out of the water. The 7th of August, Friday, is even bigger: 20 ft to 23 ft from the E with an 18-second period and energy in the very strong range (23903 to 33192). The wind is offshore in the morning, which is a huge plus, but the swell is way too big for most breaks. Only the best reef setups and experienced surfers should even think about it.
After that, the swell drops quickly. The 8th of August goes flat for the afternoon, but the 9th of August Sunday morning brings a nice cleanup: 4 ft from the E, 11-second period, glassy conditions. That’s a really nice, clean, smaller day for the intermediate crowd. Then the 10th of August Monday morning is the final highlight: 6 ft from the E, 15-second period, glassy wind, and excellent conditions for experienced surfers. The energy is a solid 1560.
So, to sum it up: the first week is a dud. The best surf is on the 6th and 7th of August, but it’s big and only for experts. The 9th and 10th of August are the best bets for clean, rideable waves for most of us.
Take it easy,
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.
