The Lowdown

G’day, I’m Rusty. Let’s talk about Guillotines. This point break has got some serious potential locked away inside this 16-day window if you have the skills, but there’s a long wait and it’s not for the faint-hearted.

Looking at the run as a whole, the first week is pretty much a write-off. From now through to the start of September 8, the surf is weak and mostly messy. There are days with tiny swell under 2ft, short periods, and winds that are either cross or onshore. The combined energy values are stuck in the low to moderate range (47 to 168) – not enough to get excited about, and the conditions are just poor.

You’ll have to sit through a long gap of about a week with no real recommendation. But then, the script flips.

The standout of the whole forecast is Wednesday, 9 September. On that Wednesday morning, Guillotines should be absolutely pumping. We’re looking at a clean 7ft swell coming from the south with a period of 10 seconds – solid groundswell that’ll have proper shape and power. The combined energy reading is 920, which tells you there’s strong wave energy building in. And the wind? Dead calm so glassy conditions. You won’t find much better than that. The afternoon is still rideable at 6ft, but the wind turns a little cross-onshore, so get out there in the morning. This is big, powerful surf – over 8ft means this is strictly for experts. If you’re not experienced, stay on the sand.

There are a couple of other moments worth a mention. On Monday morning, 7 September, there’s a pulse of messy 5ft NE windswell, but the wind is onshore and there’s rain – not worth paddling out for. Later, on Tuesday morning, 15 September, the wind swings offshore from the SSW at 25 km/h and the swell is tiny at 1.0ft – clean but unrideable. Then on Wednesday morning, 16 September, you get another glassy morning but only 2ft – surfable but ordinary.

Throughout this period, the water temperature is about average for the time of year. Nothing unusual there.

Because this break is *inconsistent* and rarely turns on, the 9 September session is a true gift if you’re an advanced surfer. And remember, a point break loves this kind of longer-period south swell – it’ll line up nicely.

Crowds are possible here (listed as *sometimes*), but on a day this good you can expect other locals to have the same idea.

Stay patient, pick your day, and charge it when the window opens.

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.
