The Lowdown
Alright folks, let’s have a look at what’s coming down the pipe for the next couple of weeks. It’s Rusty here and, truth be told, this one is a bit of a slow burner with some real fire at the end.
Right off the bat, things are pretty flat and sad. For the first week, from the start up through to the 6th of September, there’s just nothing doing. We’ve got tiny waves, mostly puny stuff around 1 ft to 3 ft, with weak combined energy (35 to 123) and winds that are not playing nice. Most of the time it’s cross-shore or choppy, so just keep your board in the car and save your energy.
The first glimmer of something rideable shows up on Monday the 7th of September. Guillotines might have a few 3 ft, south swell lines wrapping in with a 10-second period. The water’s sitting at 62°, which is pretty normal for the time of year. The wave energy is still low (148 to 213) but the wind flips to a glassy morning and a clean cross-off in the arvo. It’s surfable but nothing to get excited about. That break is notoriously *inconsistent*, so it’s fitting that it takes a whole week just to see a mediocre wave.
Then we hit Wednesday the 9th of September and things start to rumble. A solid 7 ft south swell shows up, with a 9-second period. The wind goes fresh offshore from the SSW and it’s clean, but the combined energy has kicked up to a solid 992 – we are talking moderate energy now. Thursday the 10th gets even punchier: 10 ft to 12 ft of S swell, period at 11 seconds, energy roaring up to 4425. The wind holds offshore at 19 mph. This is getting serious. It’s big and it’s raw, so this is for experienced surfers only.
But the real standout, the one you mark on the calendar, is Friday the 11th of September. The morning session looks absolutely pumping at Guillotines. A 13 ft south swell, period a long 11 seconds, and the combined energy hits a massive 7238. That is very strong wave energy, right in the wheelhouse for a point break. The wind is glassy off the land at just 3 mph, so the face will be clean and lined up. These conditions are exceptional for expert surfers. Because it’s a point break, that long period will wrap in beautifully and give you those long, powerful walls. Mind you, it is *inconsistent* here, so you might have to wait for the sets, but when they come, they’ll be worth it. This is the pick of the whole forecast.
Later that Friday afternoon, the swell drops to 10 ft, period to 10 seconds, with a cross-shore wind – still plenty of push but less clean.
After that peak, we see the swell dropping through the weekend, with a small bump on Sunday the 13th. A 5 ft SE swell with gentle offshore 9 mph winds gives clean but much smaller surf. The energy is moderate at 458, so it’s a good option for someone wanting a mellower session after the big day.
The final few days out to the 16th get small again, mostly under 3 ft. So in short, suffer through a flat start and then get ready for a thumping, short-lived pulse around the 11th. That’s the one.

Further information to help with frequently asked questions about our surf forecast for Guillotines may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
