The Lowdown
Alright, Rusty here, lookin' at the charts for the next couple of weeks. Honestly, it’s a bit of a slow burn. We’ve got a whole lot of nothing for a solid stretch before the ocean finally wakes up. The first real surfable day is a Thursday, but it's ordinary, and it stays that way for a long time.
It’s a dry spell from the start right through to the end of August. The first few days are just flat and messy, with maybe a tiny knee-high wave now and then, but the wind is all over the place. We’re looking at a gap of about two weeks where even the morning glass-offs only give you tiny, weak waves. The energy is just a whisper, with combined swell energy readings in the double digits and low triple digits, barely enough to get you wet. It’s not going to be worth paddling out for.
The only true standout, the one that makes all this waiting worth it, comes in the deep forecast. It’s a long-range promise, so keep your fingers crossed, but Thursday the 27th of August is looking like the day. That’s when the joint, Guillotines (point), finally lights up. We’re talking a solid 8 ft to 8 ft of swell, pumping in from the South. That swell is packing some serious grunt, with combined energy readings well over 1000. This is proper groundswell territory, perfect for that point. The wind is clean, too – glassy in the morning, turning to a clean cross-off in the afternoon. This is not for the faint of heart; at this size, over 8 ft, it’s strictly for the experienced crew. The crowd at Guillotines can be a problem on a good day, and on a day like this, you better believe it’ll be busy.
So, for now, save your energy. The setup is clean, but the waves are just not there. By the 27th, we should have a proper session on our hands, but it’s a long way off.

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.
