The Lowdown

Alright, this is Rusty. Let’s have a look at what’s on the cards for Udo Shrine. Gotta be straight with you – the next couple of weeks are looking pretty grim, with only a tiny window of something a bit more interesting towards the end. The water temp here is sitting around 84°, which is pretty normal for this time of year, no real anomaly to speak of.

The good news is, we don’t have to wait too long for the first bit of size, but the conditions are going to fight us every step of the way. The first real pulse of energy comes through on Wednesday the 2nd of September. We’ve got a 6ft swell from the SE, with a period of 9 seconds, and combined energy sitting at a moderate 670. The wind is onshore from the ENE at 9 mph, which is a bit of a bummer, but the morning window is the only one worth even a glance. The afternoon sees the wind pick up and the swell drop a little, so it’s not much better.

Honestly, the whole first week is a write-off. We get a massive spike on Thursday the 3rd with a 10ft SSE swell, but it’s accompanied by a fresh cross-onshore breeze and the whole thing is lumpy and messy. By Friday the 4th, the wind is howling from the SE at 25 mph, making the 8ft to 10ft swell just a wall of chop. The energy is strong in there (1206 to 1056), but you’d be fighting a losing battle. A lot of this period is just too blown out for a paddle, and the cross-shore winds might actually make it more interesting for the kite crew than for us.

There’s a bit of a lull over the weekend of the 5th and 6th, with tiny, weak swells and strong cross-onshore winds. That run of poor conditions stretches right through until the 8th of September.

Now, here’s the only real standout in the entire 16-day window. On the morning of Wednesday the 9th of September, we get a serious dose of power. The swell jumps to 13ft from the ESE, with a period stretching out to a meaty 11 seconds. The combined energy is a whopping 4231 – that is a lot of water moving. The wind is only a light 6 mph from the NNW, so it’s just a light cross-shore breeze. This will mean, for this spot and what we’ve got here, the conditions will be as clean as they get. The water will have some small wind ripples, but it’s the best we’re gonna get. That 13ft is not for the faint-hearted; this is expert territory only, as anything over 8ft gets serious. This is the one to circle. The afternoon sees the wind swing onshore again and the quality drops off, so it’s a short window.

The following days after the 9th fade fast. The rest of the second week is filled with risk of thunderstorms, onshore winds, and dropping swell. There’s another big bump on the 16th of September, with a 15ft ESE swell and a period of 13 seconds (very long period), but the wind is a fresh onshore 22 mph. That kind of wind on that kind of swell at a reef setup is just dangerous and ugly.

In short, the whole run is pretty bleak except for that one morning on the 9th of September. If you’re an expert and can make that 13ft window, you might get a few that are worth the paddle. For everyone else, it’s a staring contest with a flat or choppy ocean.

Rusty.
