The Lowdown
Rusty here again, breaking this down for you fellas who think in feet and miles per hour.
We’re in a sorry state for the first week or so. From Thursday the 13th all the way through to about Thursday the 20th, there’s basically nothing. The swell is tiny, weak as dishwater, and the wind is all over the shop. Save your energy.
But hold onto your board, because the back half of the forecast lights up. The big daddy is Thursday the 27th of August. That morning, you’re looking at a solid 6ft south swell, with a clean cross-offshore breeze out of the west. The energy reading is 666 – that’s proper meaty. Then comes the afternoon: the swell jumps to a legitimate 7ft from the south, with a period of 10 seconds, and the energy goes through the roof to 1611. The wind stays clean from the west-southwest, cross-off. This is excellent stuff, but it’s for experienced surfers only – that’s big, powerful water on the point. Crowds are “sometimes”, so you might see a few other boats, but it won’t be packed. The direction is a perfect match for what Guillotines likes.
Friday the 28th morning is also a beauty: a glassy 6ft south-southeast groundswell, with 493 energy and a 9-second period, and barely a breath of wind. The arvo gets back up to 7ft but the wind swings east and onshore, putting a bit of bump on it. Still rideable, but the Thursday session is the winner.
The water’s sitting around 63°, a little on the warm side for the season, so no need for the thick rubber.
In short: don’t bother for the rest of this week. Wait for the 27th of August. That’s your session. The 28th morning is the backup plan. It’s an inconsistent break, but when it goes, it goes 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.
