The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s lining up for us over the next couple of weeks at Guillotines. I won’t sugarcoat it – the first week is a real struggle. We’ve got a long dry spell of poor conditions before things start to show some promise. There’s a gap of about 12 days with no real surf on offer before we get a couple of windows that look worth paddling out for.
The first bit of decent action comes on the morning of Wednesday, 2nd September. The wind is light and offshore from the WSW, leaving the surface glassy and clean. We’ll see a clean 3ft swell from the ENE. The combined energy is moderate at 305, and with a period of 11 seconds, it’s a legit groundswell. That’s a good sign for a point break like Guillotines, as it’ll wrap in nicely. It’s an inconsistent spot, so don’t expect non-stop action, but when a set comes through, it’ll be well-shaped. The water temp is sitting at about 63°F, which is pretty much normal for this time of year.
Then, the next morning – Thursday, 3rd September – is the standout. We’re waking up to a glassy, clean surface with no wind. The swell is a touch bigger at 4ft, still from the ENE, and the period holds at a long 11 seconds. The combined energy is strong at 397, so there’s some real push behind it. This is the best call of the whole outlook. The waves will be cleaner, with more power, and it’s an advanced wave, so suited for the crew who know what they’re doing. Just be aware that it’s inconsistent, so you’ll be waiting a bit between sets.
After that, the conditions drop off again into the second week, with a return to choppy, onshore winds and poor surf quality. So, the takeaway is: sit tight through the first week, then circle Wednesday the 2nd and especially Thursday the 3rd of September. That Thursday morning is the real gem.
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.
