The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s on the menu.
We’ve got a solid run of swell heading our way for the first part of the period, starting Tuesday the 8th of September. This is all focused on Guillotines, an advanced, inconsistent point break. The early-morning session on Tuesday is the pick of the next few days. We’re looking at a 7 ft south-southeast swell, with a period of 8 seconds and a moderate combined energy of 1054. The wind is a gentle offshore from the SSW, so that point will be clean and lined up. The water temperature is sitting at 63°, which is pretty much average for the time of year.
The real standout, though, is Thursday the 10th of September. The swell jumps to a solid 8 ft from the south with a 10-second period, and the combined energy is pumping at 2130 in the morning and 2211 in the afternoon. This is serious, powerful groundswell and with a long period like that, Guillotines will handle it beautifully. The wind is offshore from the SSW in the morning and a clean cross-offshore in the afternoon. This is proper, heavy expert territory—over 8 ft and only for experienced surfers. Don’t even think about it if you’re a beginner. Crowds are possible here at times, but with that size and difficulty, you might have a bit more room.
After that, Friday morning the 11th still has some fun 5 ft south-southeast swell, but the big story is the glassy conditions. Absolutely still, no wind. That’s a rare treat, so if the swell is holding, it will be super clean. After lunch, the wind turns and things get choppy.
By the weekend, the swell drops away fast. Saturday the 12th is small and weak, and from Sunday the 13th right through to Tuesday the 15th, it’s mostly flat or tiny with onshore winds. There’s a little blip on Tuesday afternoon the 15th with a 8 ft southeast swell, but it comes with a strong cross-offshore wind and marginal conditions. Not worth changing plans for.
The following week is pretty quiet. Wednesday the 16th morning offers a clean 5 ft south swell with a long 12-second period, but it’s a shadow of what we had. After that, it’s a long stretch of small, weak, generally poor surf through to the end of the period on the 23rd. A few knee-high waves with onshore winds is about all you’ll find.
So, to wrap it up: the best wave of the whole 16-day run is Thursday the 10th of September at Guillotines. Solid south swell, clean winds, and that point should be firing for the experts. Friday morning is a glassy bonus.
Rusty.

Information about the Guillotines Surf forecast
The above surf forecast table for Guillotines provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Guillotines can be found by selecting the local surf guide option on the grey menu. Our Guillotines surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Guillotines) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
