The Lowdown
Right, let’s have a proper look at what’s on offer. It’s gonna be a bit of a slow burn for the next week or so at Guillotines, a heavy, advanced point break that’s pretty picky about when it turns on. It’s inconsistent at the best of times, so when it does fire, you gotta be on it.
For the first stretch, we’re looking at tiny, weak surf. Sunday afternoon and through Monday, we’re talking 2ft to 2ft of sloppy, short-period S swell, blown out by onshore or cross-onshore winds. The energy is low (131 to 163), so don’t even bother paddling out. Tuesday morning is clean with a light cross-offshore breeze, but it’s still only 2ft of weak NE windswell (87) – surfable but very ordinary. Tuesday arvo gets a jump to 6ft, but it’s messy with a strong S wind and a period of just 6 seconds; that’s a no-go.
Then Wednesday the 16th is where we start to see some serious size. A solid 10ft S groundswell rolls in, with a huge energy jump (1295 to 1433) – that’s some proper grunt. Winds are strong offshore SSW in the morning, dropping to a cross-offshore by arvo. That said, 10ft is expert territory, and on an inconsistent point, you’ll be waiting for the sets. It’s a standout for size and power, but only for those who know what they’re doing.
Thursday the 17th morning is the real gem of this first week. We’ve got 7ft of clean S swell, light offshore SSW wind, and the energy is still pumping (715). The forecast says expect very good surf conditions. The swell direction (SSE) isn’t bang on the optimum SE, but it’s close enough, and with that glassy offshore wind, Guillotines could be firing. It’s still a big, powerful wave, so not one for the learners.
Friday the 18th morning is glassy with a light east wind, but the swell drops to 4ft (energy 258) – it’s clean but ordinary. The weekend is a write-off with tiny 0.7ft to 1ft junk.
Monday the 21st brings another pulse: 7ft of S swell (energy 871) with a clean cross-offshore breeze in the morning. That’s another solid option, though the morning session is your best bet before the wind swings cross-onshore in the arvo.
After that, it’s mostly poor through to the end of the period, with a brief glimmer on Monday the 28th: 7ft to 7ft of SSE swell, clean offshore to cross-offshore winds, and energy back up to 588 to 866. The wind and size line up well, and the swell direction is a better match for the optimum.
Water temp is around 64°, which is a touch warmer than average for this time of year – not a big deal, but nice to know if you’re in a spring suit.
Overall, the standout sessions are Thursday 17th morning and Monday 28th morning. Those are the ones to circle. The rest is either too small, too messy, or too big for anyone but the hardcore. Guillotines is a fickle beast, but when it lines up like those mornings, it’s worth the wait.

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.
