The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Guillotines over the next couple of weeks. It’s a bit of a mixed bag, but there are definitely a couple of mornings worth setting the alarm for.
The first solid window shapes up on Thursday, the 27th of August. That morning, we’ve got a clean 4ft swell rolling in from the south with a modest 9-second period. The wind is light and offshore from the south, so Guillotines should be looking pretty tidy. The combined swell energy is sitting at a moderate 308, so there’s enough push to get into gear. This is likely the pick of the first week.
Friday the 28th backs it up with another clean morning. Swell is a touch bigger at 5ft, still from the SSE, with a slightly longer 10-second period. Winds are offshore from the SSW, and the energy jumps to a strong 508. This is going to have a bit more grunt, and if you’re comfortable in the overhead range, it’s going to be fun.
But the real standout of the whole outlook? Saturday morning, the 29th of August. We’re looking at a solid 5ft from the SSE, a clean 10-second interval, and combined energy of 695. That’s some serious juice. Winds are light cross-off from the SSE, keeping the surface clean. Guillotines is a point break, so it handles a longer period swell well, and this setup has the makings of some really good, consistent waves. The water temp is about average for this time of year.
Now, the catch: Guillotines is inconsistent. It doesn’t fire all the time, and it’s an advanced wave. When it’s on, it’s on, but don’t expect a guarantee. Also, crowds are possible here, so get in early.
Sunday the 30th offers a morning of glassy conditions with a smaller 3ft south swell, but it’s not the same quality as Saturday. From there, it gets quiet. We hit a dry spell from Monday the 31st of August all the way through to Friday, the 5th of September. There are a few days with tiny, poor surf, and a couple where the swell bumps up but gets wrecked by onshore or cross winds.
Then, on the 10th of September, a glimmer way out at the 16-day mark. The Thursday morning shows a chunky 8ft south swell with an 8-second period and a strong 607 combined energy. The winds are glassy from the west, which sounds incredible. However, a 8ft swell is expert territory, and the short period means it could be a bit shifty. This one is promising but less certain this far out.
Overall, you want to be looking hard at the morning of Saturday the 29th of August. That’s the day. Get it while it’s good.
Rusty out.

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.
