The Lowdown
Alright, Rusty here. Let’s talk about Guillotines.
Right off the bat, the first few days have some decent swell rolling in, but we need to pick our moments carefully. The water temp is sitting at 63°F, which is pretty normal for this time of year.
Wednesday the 26th starts with a bit of a mixed bag. Morning has a 5ft S swell, but a cross-off wind from the S at 12 mph is going to bump it up a bit. Not terrible, but far from perfect. Expect some mush. The afternoon sees the swell build to 6ft from the S, combined energy is moderate (580), and the wind drops to a light 6 mph from the S. That’s a major improvement – the surf cleans up and looks pretty good if you can get out there.
Now, the standout of the whole window? Thursday the 27th morning is the real gem. We’ve got a 4ft S swell, period pushing 8 seconds, and here’s the kicker: glassy conditions. That’s a major positive. The combined energy is 268 – solid – and the wind is mere 3 mph from the S, dead calm. Guillotines is a point break and it really likes a SE swell direction, but this S swell will wrap in nicely. This is the session to plan for. Clean, glassy, and not too big. Crowds are possible here, so get down early.
Friday the 28th morning is another good call. Swell is 5ft from the SSE, period bumps up to 10 seconds, a light offshore from the SSW at 6 mph should groom it nicely. Combined energy is a meaty 551. The swell direction (SSE) is getting closer to that SE optimum, which is a bonus. This could be a really fun session. The afternoon goes cross-on, so morning is the move.
Saturday the 29th morning sticks with a 5ft S swell (7 seconds), cross-off conditions, combined energy at 465. It’s workable and clean, but lacks the period of the earlier days. Still worth a paddle.
From Saturday afternoon onwards, things start to fade. Sunday the 30th and Monday the 31st drop to 3ft, then 2ft. Glassy mornings are nice for a log, but the energy is weak (around 148). The rest of the week into early September is a flat spell. There’s a desert of small, weak, and often choppy surf from the 1st to the 7th of September. Don’t bother. You’re looking at 1ft to 2ft S swell with poor wind alignments. There’s a gap of nearly 7 days with no real recommendation.
Late in the window, on Monday the 8th of September morning, a little pulse shows up again. A 2ft S swell with a 10-second period, light offshore wind from the S at 6 mph, combined energy at 119. It’s surfable but ordinary – nothing more than a longboard or foiler session.
So, to sum it up: Thursday 27th morning is the crown jewel – glassy, clean, and solid. Friday 28th morning is the runner-up. After that, you’re waiting a long time for anything worthwhile.
Rusty, signing off.

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.
