The Lowdown
Alright, let’s get into it.
First off, I gotta be straight with you. The next week and a half is looking pretty grim. We’ve got a lot of small, weak, and messy conditions on the table. It’s going to be a grind just to find a wave with any sort of pulse. We’re looking at a solid stretch of days where you might be better off doing anything else. There’s a real gap in proper surf from now until the end of the month.
The good news is that things start to change as we head into the first week of September. We’ve got some pulses of energy showing up, but the early part is going to be a test of patience.
Around the 26th, Wednesday afternoon, we finally see something. The swell bumps up to about 5ft, coming from the NE with a period of 8 seconds. The energy jumps to 430, which is a solid kick. But, more importantly, the wind is offshore from the SW. It’s a clean one, a bit of a highlight after all the junk. The waves at Guillotines (South) should actually be holding some shape, but we’re talking about an inconsistent spot here, so patience is key. It’s not a day for anyone but the advanced crew, as the size is pushing it.
Then, we get another chance on the morning of the 30th. There’s a lump of 5ft from the SSE, and it’s blowing offshore from the SSW at 25 km/h. The energy is at 292. Expect a bit of power in the water, but it might be a bit wild. It’s a Sunday, so you might have to share it, though the quality could be there for a few.
The real standout, the one to circle on your calendar, is the morning of Friday, the 4th of September. This is where it’s at. We’re looking at a 7ft swell from the S with a 7-second period. The energy reading is a huge 725, the biggest we’ve seen. The wind is glassy from the WNW. That’s a recipe for some proper waves at Guillotines. This is a day for experienced surfers only, as 7ft is well past what a beginner should be around. The direction is solid, and that glassy surface is going to make all the difference. It’s a little far out, but this one has some serious potential written all over it.
The afternoon of that day also looks good with 5ft and offshore winds, but the morning is the pick. After that, it fades back down to smaller, cleaner leftovers for the 5th and 6th.
So, don’t get too frothy for the next week. Bide your time, check the forecasts, and get ready for the 4th of September. That’s your real shot.

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.
