Table - best surf conditions forecast for Udo Shrine over the next 16 days.
Alright, let’s break it down. For the next couple of weeks, it’s a pretty quiet stretch, with only a couple of windows worth getting amped about.
The first real chance comes Monday morning, July 13, at Udo Shrine. It’s a reef break, so you need to be on your game. The water’s a bit colder than usual for this time of year, sitting at 80°, with a 3° anomaly—so it’s noticeably cooler.
That Monday morning, the swell is coming from the south at 5 ft, with a period of 11 seconds—that’s a proper groundswell with good energy and shape. The combined energy is 630 (moderate wave energy), and with a light offshore breeze from the southwest at 3 mph, it’s gonna be clean. This is easily the standout session of the outlook. Keep in mind, it’s an inconsistent break and crowds are often around, so you might have some company. The swell direction (S) matches the optimum direction for this spot, so it’s really lined up.
By Monday afternoon, the wind picks up a touch and goes cross-offshore, the swell drops to 4 ft, and the energy falls to 401. It’s still okay, but not as good as the morning.
Tuesday into Wednesday, things get smaller and more ordinary. On Tuesday morning, July 14, we’ve got 3 ft south swell with a 9-second period, light offshore wind, but it’s pretty weak—175 energy. It’s surfable, but nothing to write home about. Wednesday stays small, with a 3 ft swell and a 12–15 mph offshore wind, which is a bit strong for the wave size.
From Thursday, July 16, through to the weekend, it’s mostly flat or very small, with glassy conditions but barely any swell. On Saturday, July 18, there’s a 2 ft easterly pulse with glassy wind, and Sunday, July 19, shows a bit more life with a 3 ft easterly swell and 130 energy, but the wind turns cross onshore in the afternoon.
Then, on Wednesday, July 22, we get another decent morning. A 4 ft east swell with a 9-second period, glassy conditions, and 235 energy. It’s not the size of the Monday, but it’s clean and surfable. That’s the second highlight.
After that, things drop off hard. From Thursday, July 23, through the end of the month, it’s almost all flat—swells of 1 ft to 2 ft, with very low energy. The only exception is Sunday, July 26, where a 4 ft to 4 ft southeasterly swell shows up, but the wind is onshore and there’s a risk of thunderstorms, so it’s messy.
The run from July 23 to July 25 is a real dead zone—nothing worth paddling out for. Then on July 28, we get a small 2 ft south swell with glassy wind, but it’s weak.
So, bottom line: if you want the best wave, hit Monday morning, July 13, at Udo Shrine. That’s the standout. The Wednesday morning, July 22, is a decent backup if you missed it. Everything else is either small, weak, or blown 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. 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.
