The Lowdown
Alright folks, Rusty here. Let's get stuck into the outlook for this stretch of coast.
We’re looking at a solid run of surf from an exposed reef break that’s built for advanced crew only. There's no gap at the start; the first recommendations kick off right away. The water temp is sitting at 80° with just a tiny nudge above normal, so it’s feeling pretty much average for this time of year.
Yo Yo's-The Wedge is the only game in town for this whole 16-day window. It’s a reef break, very consistent, and it’s exposed to the swell. The best direction for waves is from the SW, which is exactly what we’ve got coming in. Morning sessions are mostly cross-shore with a bit of chop, but afternoons clean up nicely with that cross-off breeze from the SE. The energy is solidly in the strong range for the first week.
Tuesday the 1st kicks off with a 7 ft SW groundswell, period a long 18 seconds, and combined energy of 2813. That’s a lot of push for an advanced wave. The cross-off wind in the afternoon cleans things up proper. This sets the tone. Wednesday the 2nd holds similar size and shorter period at 17 seconds, energy at 2275, still clean in the afternoon. By Thursday the 3rd the swell drops to 5 ft, still a long 16 second period, energy down to 1329.
We get a bit of a lull Friday the 4th with 4 ft and shorter 14 second period, energy dropping to 760. But it picks back up quick. Saturday the 5th sees 6 ft and a wind that goes more cross-shore, making it a bit lumpy in the morning, but the afternoon cleans up with 6 ft and 16 second period from the SSW, energy 1743.
The standout window looks to be Monday the 8th of September through Wednesday the 10th. On Tuesday the 8th, we hit 8 ft in the afternoon with an 18 second period from the SSW and combined energy of 4531 – that’s a *lot* of power. This is for experts only, no question. The wind is offshore in the afternoon, which will make it glassy. If you are not absolutely on your game, this wave will eat you up, but for the savvy crew, it’s going to be firing. The early morning on the 8th is still 8 ft with a 19 second period and energy 3749, but the wind is cross-shore then, so wait for that afternoon glass-off. Wednesday the 9th is still pumping clean in the afternoon at 7 ft, 16 seconds, and 2839 energy.
After that peak, the swell slowly backs off through the second week, holding around the 5 ft to 6 ft mark with periods still in the 15-second range. Energy stays moderate to strong. The wind pattern stays the same: mornings a little scrappy, afternoons clean. The period is long, so at a reef setup like this, the waves will have shape and power, but be aware of the longer lulls between sets.
Late in the window, on Wednesday the 16th, we see a light wind morning with just 10 km/h from the SSE, giving only light cross-shore ripples, with a 6 ft SW swell at 15 seconds and energy 1708 – a solid way to wrap things up if you can wait that long. Crowds are "often" here, so expect some company at a wave this good.
Rusty, signing off.
