The Lowdown
Alright, folks, Rusty here. Let’s look at this upcoming stretch for Udo Shrine.
First up, the water temp is sitting at a very comfortable 84°, which is pretty much bang on average for this time of year, so no surprises there.
Now, the next week or so is a mixed bag at best. We get a few small windows of clean surf, but honestly, the first real highlight doesn’t show up until Saturday the 5th of September. That morning, we’ve got a solid 12ft swell out of the ESE, with a light offshore wind. The wave energy is pumping hard (2656), and the conditions are set to be excellent for experienced surfers, but the size makes it a big-wave day only. The period is 11 seconds, so it’s got decent grunt, but that size will be too much for the average punter. The afternoon holds 13ft from the same direction, still clean, but the tide might play tricks on you.
The next standout is Sunday the 6th of September. This is the best of the whole run. We’re looking at a massive 15ft groundswell from the SSE early, with a very long 12-second period, pushing the combined energy through the roof (5954). The wind is a gentle cross-shore, so there’s only a slight chop. This is a serious, heavy reef set-up; for experts only. The period is long enough that it’ll be working well here at the reef, but that size and power isn’t for the faint-hearted. The afternoon eases to 12ft, still solid, but again, manage your expectations on the tide.
After that big pulse, things get messy with strong onshore winds and storm risks from the 7th through the 9th. But keep an eye on Thursday the 10th of September. We get a nice, clean window with a 4ft to 5ft SE swell, light offshore winds, and good conditions. The energy is moderate (323-407), making it a far more relaxed and fun-sized day for the intermediate crew after the chaos.
And then Friday the 11th of September morning is worth a mention. Glassy conditions, a 6ft SE swell, and very good quality. The period is shorter at 9 seconds, so it’s a bit more local wind swell, but the glass-off will make it clean and fun.
Overall, if you’re an expert, circle Saturday 5th and Sunday 6th of September. For everyone else, Thursday 10th and Friday 11th of September are your best shots. The crowds here are often an issue, so expect company.
Rusty.
