Alright folks, Rusty here. Let's have a look at the coming weeks for Udo Shrine. We've got some real solid swell on the cards, but the wind is going to be the main character in this story for a while. This is a reef break that'll handle a bit of size, but it needs the right conditions to really shine.

The first opportunity kicks off this Friday, the 10th of July. The ocean is already rumbling with a solid 13 ft SSE swell, packing some serious grunt – we’re talking a combined energy of 9423 (moderate to strong). The water is sitting at 79°, which is a noticeable 3° colder than average for this time of year, so a bit of a nip in the air and the water. However, that Friday afternoon is blown out with a stiff 9 mph cross-onshore wind from the east, making it pretty choppy. It’s surfable, but it's not the cleanest. The size is legit, but it's a battle.

Saturday the 11th holds more size, with the swell staying around the 13 to 15 ft range from the SSE and S, and energy readings over 10,000 (strong). But again, we’ve got cross-onshore winds and the risk of thunderstorms messing with the surface. This is big, heavy, and messy – probably more of a challenge than a joy.

By Sunday morning the 12th, the swell drops to a still-chunky 8 ft from the south, and we finally see a shift in the wind. It goes cross-shore, and then in the afternoon we get a light 9 mph cross-offshore breeze from the SSE. The combined energy drops to 1686 (weak to moderate), but the surface cleans right up. This is the first real standout window. With a 13-second period, it’s a proper groundswell running, offering some good shape and power. This is when Udo Shrine will actually look like a wave.

The best bet of the whole forecast is Monday the 13th. We get a 5 ft S swell at 11 seconds with an offshore wind from the southwest at only 3 mph in the morning. Combined energy is 640 (weak), but the conditions are described as "very good" and clean. This is the session to target – glassy, lined-up reef waves. It’s smaller, so perfect for a wider range of abilities. The afternoon holds similar 5 ft surf with a light cross-offshore wind, still clean.

After that, the surf tapers off significantly. From Tuesday the 14th through to Saturday the 18th of July, it gets tiny and mostly blown out. We're looking at waves under 3 ft with onshore or cross-onshore winds. It's a flat spell, essentially.

Then on Sunday the 19th, a new pulse arrives with a 8 ft S swell (moderate energy of 1736) and a 12-second period, but the wind swings hard onshore from the east at 12 mph. It’ll be junky and poor. This pattern of onshore winds and messy, choppy surf persists right through to the 22nd of July. With the swell size building back up to 8 ft and strong winds, this is looking more like a kite-surfing setup than a paddling session.

We finally get a glimmer of hope around the 23rd and 24th of July. A new, long-period groundswell shows up – 4 ft to 7 ft ESE swell with a period of 13 to 15 seconds (very long period). The combined energy jumps back up to 1274 and 2016 (weak to moderate). The catch? The wind is still cross-onshore or onshore. The long period will make these waves powerful and lined up on the reef, but the wind will keep them from being perfect. These are promising for a late session but less certain with that breeze.

The final days of the outlook, the 25th of July, show a 6-6 ft S swell with a decent 11-12 second period, but again, cross-onshore winds hold. The energy is moderate.

So to sum it up: Monday the 13th of July is the clear standout. Get it while it's small, clean, and offshore. The Friday the 10th through Sunday the 12th has the biggest swell, but you're fighting the wind. The long-period pulses late in the month are worth watching, but the wind is the big question mark.

Rusty, signing off.

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.
