The Lowdown

Alright, Rusty here. Let's talk about what's coming up.

Alright, so the first two days, Friday and Saturday, are pretty much a write-off. A tiny bit of swell on Friday morning, 2.3ft from the SSE, but it’s weak with next to no energy (74) and a short period of 7 seconds. It’s just not worth getting wet. The wind fills in and kills it anyway. Saturday’s even worse. We’re looking at a big gap of flat, messy conditions until things start to change on Sunday.

Sunday afternoon things get interesting, but not in a good way for paddle surfing. A big, raw 6.9ft southerly swell rolls in with moderate energy (1425) and an 11-second period. The wind is cross-off at Guillotines, so it'll look clean, but that size with a long period on a point break like this? It’s gonna be a heavy, straight-shooting wall. That’s expert territory, and even then, the tide might mess with it.

Tuesday the 8th is your first real standout. Early morning, we’ve got a clean 6.2ft SSE swell with a very respectable 10-second period and a healthy 886 energy reading. The wind is light and offshore from the south. This is prime Guillotines conditions – solid, lined-up waves with a clean face. Crowds are possible here, it’s a known spot. The water temp is 63.1°, which is 1.3° above average, so about normal for early September.

Thursday the 10th is the big one, but it’s for experts only. A massive 9.8ft southerly groundswell hits the Thursday morning, pushing over 3000 energy, with an 11-second period. The offshore wind will groom it, but that’s a serious, powerful wave. By Thursday afternoon it jumps to 11.5ft with a 14-second period and energy spiking to 6140. You’d need to be on your game. The period is so long it might barrel too straight, but on a point like Guillotines, it could be a freight train. It’s not for the faint of heart.

Friday the 11th early morning is a fantastic session after that. The swell drops to a still-chunky 6.2ft from the SSE, period 11 seconds, and it’s glassy – dead calm. Energy is still strong at 849. That’s the sweet spot for a strong surfer.

After that, it tapers off. A few more clean mornings on the 12th and 19th of September with 4.3ft to 5.9ft swell and glassy winds, but the afternoons get chopped up. The 18th of September also shows a strong but difficult 8.2ft southerly groundswell with fresh offshore wind, but the forecast is more marginal. It’s worth watching, but the Thursday the 10th and Friday the 11th are the clear standouts.

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.
