The Lowdown
Alright, Rusty here, let's have a look at what's coming down the pipe.
You know, for a spot like Guillotines, it’s been a quiet start. We're looking at a real dry spell for the first week and a half. There's some small, clean waves around the 30th of August and the 31st, with the swell coming from the south at 3ft and a period around 9 seconds. The combined energy is weak to moderate, sitting around 166, so it's not going to blow you away. The wind is glassy in the mornings, which is a rare treat for a point break. If you're desperate for a paddle and can handle an inconsistent wave, you might get a few. But honestly, the crowds are possible here, and with that small of a swell, it'll be a long wait between sets. The water temp anomaly is about average for this time of year.
Then we hit a real flat patch. From September 1st right through to September 8th, it’s grim. The swell drops below 2ft most days, and the wind is all over the place – mostly onshore or cross-shore. Not worth getting wet for. That's a solid 8 days of nothing much to talk about.
Now, things get interesting in the second week. On Monday the 7th of September, there’s a little pulse of 3ft south swell with an 8-second period and a clean, gentle offshore wind from the south. The energy is moderate at 115. It's surfable, but still just very ordinary. The real standout is shaping up for Thursday the 10th of September. That morning is your best bet of the entire outlook. We have a 6ft south swell, 10-second period, and glassy conditions. The combined energy jumps up to 565, which is a solid moderate-strong event. That’s size, that’s period, and it’s clean. This is for the experienced crew though – at 6ft on a point, it'll be proper. The following Friday morning the 11th might also be worth a look with 4ft and glassy conditions first thing, but the energy drops back down to 248.
So, to sum it up: the first week and a half is a write-off unless you're just stoked to be in the water. The one true standout is the morning of Thursday, 10th September. Mark it. After that, it fades out again.
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.

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.
