The Lowdown
Alright, Rusty here. Let’s break down what’s coming at Guillotines. This is a point break, and it’s an inconsistent one, so when it does fire, you gotta be ready. It’s advanced only – not a wave for the faint of heart.
The first real window is Tuesday, September 8th in the morning. We’ve got a solid 6ft swell from the SSE, with a nice offshore breeze from the SSW. The water temp is about normal for this time of year. The wave energy is moderate (406), and the surf is clean. That’s your first call. The afternoon goes to crap with a cross-onshore wind, so don’t bother.
Wednesday, September 9th morning is clean again with 6ft swell and moderate offshore wind. But Wednesday afternoon is a beast – the swell jumps to 12ft from the S with a 25 mph wind. That’s expert-only, and it’s a heavy, dangerous mess. The energy is massive (1628).
Thursday, September 10th morning is the real standout. You’re looking at 8ft from the S with a 10-second period, blown by a 12 mph offshore wind. The energy is strong (1099), and the waves are clean. This is the one. The afternoon is still big but the wind goes cross-off, so it’s less clean.
Friday, September 11th morning is a gem: 6ft, 9-second period, and glassy. The wind is dead calm from the SE. The energy is moderate (492), but with that glass, it’ll be butter.
After that, the swell drops fast. Saturday, September 12th and Sunday, September 13th are small and weak, with onshore and cross-onshore winds. The energy is low (140-317). Not worth a paddle.
From Monday, September 14th through the 16th, we hit a flat spell. Waves drop below 3ft, the energy is pathetic (below 100), and the wind is all over the place. A few days of nothing.
Tuesday, September 15th afternoon sees a sudden spike back to 6ft from the SSE, but it’s a short-period, wind-driven wave. The energy is moderate (536) and it’s clean, but it won’t have the quality of the earlier days.
Wednesday, September 16th is back to small, weak waves with onshore winds. Not much.
Thursday, September 17th morning gives us a glassy 3ft swell, but with a super long 14-second period. That’s a groundswell, and it’ll wrap nicely at a point like this. The energy is moderate (654). A quiet, clean morning.
The rest of the run into September 23rd is mostly small, weak, and blown out. There’s a spike of 8ft on Saturday, September 19th morning, but it’s messy with a cross-onshore wind. That’s a kite-surfing day, not a paddle day.
So listen up: the clear winner is Thursday, September 10th morning. The swell size, the clean offshore wind, and the strong energy make it the best on offer. The glassy Friday morning is a close second for a quieter, more relaxed session. Don’t miss that Thursday.
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.
