The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks.
We’re looking at a solid run of groundswell, but it’s not a free-for-all. This is an advanced reef setup, and it demands respect. The water’s sitting at a warm 79°, which is pretty much bang on average for this time of year, so nothing unusual there.
The first real action kicks off Tuesday afternoon, the 8th of September. We’ve got a clean swell of about 6ft rolling in from the SSW with a very long period of 18 seconds. That’s proper groundswell energy, and the combined energy is a solid 3223 (moderate energy). The wind is a cross-off from the SE, so the face should be looking tidy. The period is long, so expect those longer lulls between sets, which makes the paddle out a bit easier, but the waves themselves will have plenty of grunt. This is for experienced surfers only.
Wednesday, the 9th, sees the swell bump up to about 8ft in the morning, but the wind turns more cross-shore, introducing a bit of chop. It’s still good, but not as clean as Tuesday. The afternoon drops slightly to 8ft, again with cross-shore wind. The energy is still strong.
Thursday, the 10th, the swell dips a little but the morning is a bit choppy. The afternoon looks better – 7ft, clean, cross-off wind. A solid session there.
Friday, the 11th, and Saturday, the 12th, keep the consistency. Saturday morning is the standout early on – 5ft, clean, gentle cross-off breeze, and the energy is still pumping at 1731 (moderate energy). It’s the sweet spot for this break if you ask me. The swell is a touch smaller, but the conditions are nearly perfect. Crowds are often here, so get in early.
The pattern continues, with clean surf and consistent SW groundswell through the middle of the month. The period stays long, mostly 15 to 18 seconds, so the quality is there for the experienced crew.
Now, hold on to your board. The real standout is brewing for the second week. On Tuesday, the 22nd of September, we see a significant jump. The swell hits 10ft in the morning, building to 12ft in the afternoon, both from the SSW. The periods are a very long 18 seconds. The combined energy explodes to 6488 and 6567 (strong to very strong wave energy). This is a serious pulse. The wind is clean cross-off. This is big wave territory – only for experts. The 23rd keeps the size at 10ft with similar clean conditions. This is the big one, the one you circle on the calendar. It’s promising, but it’s a long way out, so keep an eye on it.
So, the pick of the bunch is the Saturday morning session on the 12th for the best balance of size and perfection, and the 22nd for the big-wave adrenaline junkies. The crowd factor is a reality, but the wave quality makes it worth it.
There’s a small drop-off in energy towards the end of the month, but the swell is still around. The 19th and 20th are smaller, but still worth a look if you’re after a quieter paddle.
Rusty, signing off.
