The Lowdown
Alright, mate, Rusty here. Let’s get straight into it.
We’ve got a bit of a slow start ahead, but there’s a big payoff coming for those who can wait. The water temp is sitting at 62°F and about average for this time of year, so no surprises there.
The first few days are pretty ordinary. Saturday the 15th has some small 4ft swell from the south with a short 6-second period, and a light offshore wind keeps things clean enough. The combined energy is weak (201), so it’s small and a bit gutless. Sunday morning the 16th turns glassy with a tiny 4ft from the east-southeast, still short period, but it’ll be smooth. The afternoon picks up a longer 11-second period from the south, which gives it a bit more push (208 energy), but it’s still only 3ft. Monday the 17th is glassy again in the morning with 2ft, but it’s tiny. Then from Monday afternoon right through to the end of the 21st, we’ve got a run of poor surf – small, onshore, or cross-onshore winds, and the energy is low. Basically a flat spell.
Now, Saturday the 22nd brings a wake-up call. A solid 8ft south swell rolls in with a clean cross-offshore wind from the west-southwest. The energy jumps to moderate (877), and it’s clean. This is a decent option for the experienced crew – might be a bit much for beginners at that size. Sunday the 23rd is glassy again in the morning with 3ft, but it’s dropping off.
Then there’s another gap of poor conditions until Wednesday the 26th. That morning, we get a fresh offshore wind from the south at 30 km/h, with a 6ft swell from the northeast at 8 seconds. The energy is strong (566), and it’s clean offshore. The afternoon gets even better – moderate offshore wind, 6ft, and the energy is still solid (375). This is a good window for a surf.
But the real standout is the end of the forecast. Friday the 28th morning sees a 8ft south swell with a moderate offshore wind, and the energy is very strong (1228). That’s a solid session. But the afternoon of the 28th – wow. A massive 21ft south swell with a very long 15-second period. The energy is enormous (32046). This is a true groundswell of epic proportions, but it’s predicted to be too big for this break. Only the most expert chargers with big-wave gear should even consider it. The period is so long that it’ll be breaking a lot at the point, but it’s just too big.
Saturday the 29th morning is still huge – 16ft from the south with a 13-second period, clean offshore wind, and exceptional conditions for experts (13688 energy). The afternoon drops to 13ft, still clean but a bit cross-off. Sunday the 30th has 10ft and 8ft from the south-southeast, but the wind goes cross-shore, making it messier.
So the best bets are Saturday the 22nd for a solid, clean 8ft south swell, and Wednesday the 26th for consistent offshore winds in the 6ft to 6ft range. The big stuff at the end is for experts only. Guillotines is a point break that’s inconsistent, but when it comes, it can be magic. Keep an eye on the forecasts for those last few days – they’re promising but still a way out, so things can change.
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.
