The Lowdown
Alright folks, Rusty here with a look at what's coming our way.
We’ve only got one spot on the radar for the next sixteen days, and that’s Guillotines, a point break that's rated for advanced surfers. This place is a fickle beast – it's inconsistent, so when a window opens up, you need to be ready to move on it. The first real chance we get kicks off on Thursday, September 17.
Thursday, September 17 is your standout session. The morning will be the best of the best. We’re looking at a solid 6ft swell from the SSE with a combined wave energy of 577 (moderate). The wind is absolute gold – glassy, dead calm. That’s a rare gift at a break that likes an offshore SSW breeze. This is the one to wake up early for. The afternoon sees the swell drop to 5ft, but the wind swings onshore and it gets choppy, so get it while it’s good.
Friday the 18th still has some life with a 4ft swell from the S and glassy conditions again in the morning, but the energy is dropping (271). It'll be cleaner and smaller than Thursday.
The following week gets a bit messy. There’s a pulse of swell from the NE on Wednesday, September 24 worth noting. The morning shows a glassy 4ft, but the real event is the afternoon: a clean 6ft swell from the NE with a gentle offshore breeze out of the SSW. The energy is moderate (303), but the period is a short 6 seconds, so it won’t have the push of the earlier south swell. Still, a fun, clean option.
After that, we hit a flat spell. The 27th and 28th show some choppy, poor conditions with a messy wind, and the surf goes very small or gets blown out. There’s a flicker of hope on Tuesday, September 29 with a clean 4ft swell from the ENE and a cross-offshore breeze, but the energy isn't huge (267). The last days of September into October look like a bust; tiny surf and poor wind.
So, the big takeaway: Thursday the 17th is your golden window. It’s not a long run of waves, but that morning offers a quality, glassy groundswell at an unpredictable break. For the rest, it’s a waiting game on a fickle spot.
Stay on it.
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.
