The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Guillotines.

Guillotines is a point break, so it has that potential to line up beautifully when the conditions are right. The water is running a touch warmer than normal at 65°, which is nice for this time of year. The big news is a solid pulse of swell arrives on Wednesday the 16th. We’re looking at a strong 8ft swell from the S, carrying a moderate 9-second period. Combined swell energy is pumping at (1092). The wind is blowing clean offshore from the SSW at 19 mph, which is a major positive – the faces should be glassy and groomed. Be warned, this is an advanced break and it’s inconsistent, meaning you’ll need to be patient and pick your waves. Crowds are possible here.

Wednesday afternoon sees the swell even bigger, jumping to 10ft from the S, still with that 9-second period. The energy jumps to (1368), but the wind shifts to a cross-off from the S at 19 mph. It’s still clean enough, but the size and power on a point break at over 8ft means this is strictly for experts only.

Thursday the 17th morning is the real standout of this whole run. The swell drops to a very manageable 6ft from the SSE, still a solid 9-second period with moderate energy at (561). The killer here is the wind: light offshore from the SSW at just 6 mph. That’s glassy, perfect conditions. For an inconsistent point that can be fickle, this is about as good as the forecast gets for a clean, punchy wave in the chest-to-head high range. Get on it early.

After Thursday morning, the window slams shut. The rest of the 16-day run is mostly plagued by poor conditions, onshore wind, and fading swell. There’s a long stretch of flat and choppy days from the 18th through to the 25th, with virtually nothing worth paddling out for.

We get a faint sign of life again on Monday the 22nd. The morning shows a 5ft swell from the S with a very short 6-second period, energy at (292), but the wind is offshore from the S at 12 mph, so it’s clean. By Tuesday the 22nd afternoon, we see a 4ft SSE swell with a better 10-second period pushing energy to (518), and the wind is a clean cross-off from the SE. It’s surfable, but nothing compared to the Thursday morning window.

The final day with any mentionable surf is Thursday morning the 1st of October. A 4ft swell from the S with a short 6-second period and a light cross-off breeze from the SW gives you clean but weak little waves. Energy is low at (250).

So, in a nutshell: your window is tight. The absolute best bet is Thursday the 17th morning. Light offshore wind, decent 6ft SSE swell, and a clean point. The Wednesday the 16th is for experts only. After that, the place goes quiet for days. If you can only paddle out once, make it Thursday morning.

Stay well, Rusty.

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.
