The Lowdown
Alright, grab a coffee and listen up. This is a weird one. We’ve got a solid 16-day window, but the first few days don’t even have enough energy to get excited about. It’s almost like a false start. I’ll walk you through the whole run, but the real standout is hiding in the middle of the week.
Right now, Sunday the 6th is a total write-off. The swell is tiny at 1 feet from the NE, with a weak 7-second period. The combined energy is only 18, which is barely a ripple. You’d be floating more than surfing. Monday morning, the 7th, things finally get a pulse. We’ve got a 4 feet SSE swell, period creeping up to 8 seconds, and the wind is absolutely glassy – flat calm. The water’s sitting at 64°, which is about 2° warmer than the average for this time of year, so that’s a nice touch. But the energy is still only 226, so it’s more for the longboard or a fun log session. Still, glassy conditions are rare, so if you’re desperate, Monday morning at Guillotines is your only real option.
Then Tuesday the 8th rolls in and it’s a different story. The morning is where it’s at. A clean 7 feet swell from the SSE, period 9 seconds, and the combined energy jumps to 741 – that’s moderate energy, but it feels punchy. The wind is a light cross-off, so it’s going to be clean. This is a proper session. The surf will be well-shaped for a point break, and with that size, it’s still okay for intermediate surfers, but it’s getting a bit meaty for beginners. The afternoon is a mess with a cross-on wind, so don’t bother with that.
Wednesday the 9th is a bit of a letdown. The morning has a 3 feet SSE swell, but the energy is only 142. The afternoon ramps up to 10 feet, which is big, but the period is only 8 seconds, so it’s going to be a lumpy, powerful mess. The energy spikes to 1106, which is strong, but it’s not going to be pretty. That’s expert territory only, and even then, it’s not a classic.
Now, the standout. Thursday the 10th, morning. This is the one. We’ve got a 8 feet S swell, period 10 seconds, and the combined energy is a massive 2009 – that’s strong wave energy. The wind is glassy. Absolutely dead calm. For a point break like Guillotines, that’s a dream. The swell direction is from the S, which is not the optimum SE direction the spot likes, but with that size and period, it’s going to wrap in nicely. The water is still 64°, and the sets will be clean, hollow, and demanding. This is for experienced surfers only. The crowds might show up because it’s good, but with it being a bit inconsistent, the lineup might not be too packed. The afternoon is also 8 feet, but the wind turns cross-on, so it’s not as good, but still worth a look if you’re keen.
Friday the 11th is still good, but a step down. The morning has a 5 feet S swell, period 10 seconds, and the energy is 515. The wind is glassy again. Not as big as Thursday, but still clean and fun. The afternoon is 5 feet with a clean cross-off, so that’s a solid afternoon session too.
After that, it fades. Saturday the 12th is a write-off with a cross-on wind, and Sunday the 13th through Monday the 14th are messy with cross-shore winds and small, weak swell. The energy drops to around 300, and the swell is small and inconsistent.
There’s a blip on Tuesday the 15th morning – a 6 feet S swell, period 8 seconds, energy 583 – but the wind is cross, so it’s not clean. The rest of the second week is a slow fade. The swell drops to 2 feet to 3 feet, and the wind is either onshore or cross-off, but the energy is weak. Even the longer period on the 20th (14 seconds) doesn’t save it because the swell height is only 1 feet.
So, overall, the pattern is clear: forget the first few days, surf Tuesday the 8th morning if you want a fun session, but the absolute standout is Thursday the 10th morning. That’s the one to circle on your calendar. The rest of the run is a slow decline into small, weak surf.

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.
