The Lowdown
Alright, Rusty here, let’s break down what’s happening at Guillotines.
Right now, the ocean’s giving us a mixed bag, but there’s some serious quality hiding in the schedule if you’re patient. The first few days are a bit average, but we’ve got a couple of absolute standout sessions that’ll have the lineup buzzing.
The big news is Thursday, September 10th. That morning is your pick of the whole run. We’re looking at a solid 8ft S swell, with a 10-second period, so there’s proper energy in the water (combined swell energy of 2210 – that’s strong). The wind is offshore from the SSW at just 9 mph, so it’s going to be clean, lined-up, and powerful. This is expert territory at that size, but for those who can handle it, it’s going to be exceptional.
The other real standout is Tuesday, September 15th in the morning. That’s another pumping session with 7ft S swell and a 10-second period, and the combined energy is strong again at 1377. The wind is light from the SSE, cross-off, keeping the surface glassy. The swell direction is a touch off the optimum (SE is preferred), but the quality on offer here is hard to ignore. It’s a Monday, so it might be a little quieter for crowds – but Guillotines can get busy, so keep that in mind.
Earlier in the week, Tuesday, September 8th morning is worth a mention. You’ve got 6ft SSE swell with offshore wind from the S, so it’s clean. Not a massive standout, but a good, solid session for those who want to get wet without the peak intensity.
The rest of the period is pretty patchy. There’s a long gap from the 13th through to the 14th where it’s just poor, small, and onshore. Then we pick up again with the Tuesday the 15th highlight. After that, it fades back into smaller, wind-affected surf through to the end of the run. The 18th has a weird 19-second period swell at only 2ft, which is more of a long-period pulse than anything rideable.
Water temp is sitting at 64°, which is about 2° warmer than normal for this time of year – so it’s a touch on the warm side, but nothing crazy.
So if I’m you, I’m circling Thursday the 10th morning and Tuesday the 15th morning. The 10th is the real gem.
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.

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.
