The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Udo Shrine. Honestly, it’s a bit of a slow start. We’ve got a long dry spell before anything really gets going, so don’t rush to wax up just yet.
The first few days from Tuesday the 14th through to the end of that week are pretty flat and uninspiring. We’re looking at small, weak swells, mostly around 2 ft to 3 ft, with a few windows of clean conditions thanks to some light offshore breezes and even a few glassy moments. The water is sitting at 80°, which is a bit colder than normal for this time of year – nothing crazy, but noticeable when you’re sitting in the lineup. The wave energy is weak, with the best early reading being just 175 (combined energy). It’s surfable, but honestly, it’s very ordinary. Not worth paddling out for.
We then hit a real lull. From Friday the 17th afternoon all the way through to the morning of Tuesday the 28th, it’s mostly poor surf conditions. The swell drops to tiny, the wind turns onshore or cross-onshore, and the scores are a flat zero. There’s a stretch of over a week with nothing to recommend. It’s a dry run.
Now, here’s where it gets interesting. The standout is definitely on Wednesday the 29th. The morning session is the pick of the entire forecast. We’ve got a clean 5 ft swell from the SSE, and it’s glassy. That’s a major positive. The wave energy jumps up to 573 (moderate), and the period is a solid 10 seconds, so there’s some proper shape and power. This is the best on offer – a true highlight. Keep in mind, Udo Shrine is a reef break that’s inconsistent, but when it’s on, it’s on. It’s also exposed to the south, which is matching the optimum direction. The afternoon gets a bit bigger, 6 ft, but the wind swings cross-shore, making it less perfect. Still, that morning is the window.
The afternoon of the 29th is a bit wonky with the cross-shore wind, but the swell is solid. For the experts, that 6 ft could be a fun, punchy wave, but it’s not as clean as the morning.
So, to wrap it up: don’t bother for the next week and a half. Wait for the 29th. That Wednesday morning is the one to circle. It’s a promising call, but as always with long-range looks, it’s a bit less certain. Get ready for it.
Rusty.
