The Lowdown
G’day, Rusty here.
Let’s cut to it. The next couple of weeks have a slow start, a good middle burst, and a long tail-off. You gotta pick your days.
Saturday the 5th is flat. 2 to 2ft and messy. Not worth it. Sunday the 6th cleans up a bit, but it’s small. The afternoon jumps to 7ft from the south, but the wind is cross-off and it’s rough. First sign of life, but not the day.
Monday the 7th: morning has 3ft from the southeast, but the afternoon is better. 4ft from the south-southeast, light breeze, clean. You’ll get some waves, but it’s not special.
Now, Tuesday the 8th. This is where it gets good. Morning is glassy, 7ft from the south-southeast, strong energy (862). Clean, solid, and the standout morning. The afternoon gets chopped, so make the call early.
Wednesday the 9th is tricky. Morning has 5ft from the south-southeast, offshore and clean. Afternoon blows up to 10ft from the south-southeast with strong offshore winds and very strong energy (1054). That’s big. Over 8ft, so experts only. Not for the faint-hearted.
Thursday the 10th. This is the best of the run. Morning is 7ft from the south, gentle offshore, very strong energy (1287), described as very good. This is the day. Clean, powerful, and consistent. Don’t miss it.
Friday the 11th drops to 4ft from the south, glassy again in the morning. Still okay, but the pulse is fading.
The weekend of the 12th and 13th is mixed. Saturday is small, under 3ft. Sunday the 13th has a long-period groundswell, 5ft from the south with a 14-second period, glassy in the morning, strong energy (851). That’s a long period, so it’ll line up at a point like Guillotines, but a beach break might get a bit wonky. Still, there are waves.
From Monday the 14th, it’s a slow fade. Onshore winds, small energy, and nothing worth chasing. The 17th has a morning glass with 4ft from the southeast, moderate energy (298), but it’s not a patch on the 8th or 10th. After that, it’s mostly onshore junk.
So, the two standouts are Thursday morning the 10th – 7ft from the south, gentle offshore, very strong energy (1287) – and Tuesday morning the 8th – 7ft from the south-southeast, glassy, strong energy (862). Both are clean, solid, and at a point break like Guillotines, that’s a proper session. The 9th afternoon is big for experts only, and the 13th is a long-period promise but a bit further out.
Guillotines is inconsistent, so when these windows hit, you go. Crowds can be there, so paddle out early. Water temp is about normal for the season.
That’s the rundown. See you out there.

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.
