The Lowdown

Alright, folks, Rusty here. Let’s talk Guillotines. It’s been a pretty quiet stretch, and to be honest, the next several days are looking like a write-off for any decent waves. We’ve got a big gap here – from now through to about the 15th of September, the surf is just too small or messy to bother with. We’re looking at weak, short-period swells and cross-onshore winds chopping everything up. Not worth paddling out for.

Now, if you’re patient and don’t mind waiting, things finally get interesting around Wednesday the 16th. The standout window hits on the morning of Wednesday the 16th. A solid pulse of southerly swell rolls in, with a 7ft swell out of the south. The wind turns offshore out of the SSW, around 15 mph, so it’s going to be clean. The combined energy jumps up to a strong 561, and that’s the real deal. This is advanced-level surf – that 7ft is well into the “experts only” zone. It’s a point break and it’s fairly exposed to the swell, so it’ll handle that size, but it’s inconsistent, so you might sit for a while between sets. Still, when a set comes through, it’ll be worth the wait. Don’t expect a crowd-free session though – this spot can get busy sometimes.

After that spike, the energy pulls back pretty quick. Thursday the 17th drops to around 4ft with light onshore breezes, and then we’re back to small, poor conditions for a long stretch. There’s another pulse coming for Wednesday the 23rd, with 6ft south swell but a short period of 8 seconds, and cross-shore wind – it’s marginal at best, not the clean, powerful lines we saw on the 16th.

So, if I had to point you to the best of the lot, it’s that Wednesday morning, September 16th. Get on it early, be ready for some juice, and know that the crowds might be there with you. After that, it’s back to waiting.

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.
