The Lowdown
G’day, Rusty here. Let’s talk about what’s coming at Guillotines. This is a tricky, inconsistent point break that’s really only for the advanced crew, so don’t expect a quick fix.
Looking at the whole 16-day run, things start slow. There’s about a three-day gap from the 12th to the 15th of September where it’s small and sloppy—not worth getting wet. The first real action kicks off on the morning of September 16th.
The standout window is from the 16th through the 18th. On Wednesday the 16th of September, the swell jumps to 8ft from the south with an 8-second period, and offshore winds from the SSW at 22 mph in the morning. The afternoon bumps up to 10ft from the south, cross-off breeze, and the combined swell energy is strong (1487). This is big, powerful stuff—only for experts.
The cream of the crop lands on Thursday morning, September 17th. That morning serves up 8ft of south swell, 8-second period, clean offshore wind from the SSW at just 9 mph, and the energy is pumping at 1596. It’s a point break, so that south swell will run nicely. Water temp is about 64°F, a touch warmer than average for this time of year—nice for an early session.
After that, it fades fast. The 18th has a brief glassy morning with 3ft from the south, but it’s weak. From the 19th to the 27th of September, it’s mostly small, messy, and onshore. A few clean moments pop up around the 22nd and 23rd with light offshore breezes, but the swell is tiny. Those bigger, wind-affected days around the 25th and 26th, with 8-10ft northeast swell and onshore winds, look more appealing for kite surfing than paddle surfing.
Bottom line: if you’re experienced, Thursday the 17th of September is your call. Clean, solid, and firing at Guillotines.
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.
