The Lowdown
Right, let’s get into Guillotines. It’s a point break built for advanced surfers, and over the next couple of weeks we’re going to need some patience. There’s a real feast-or-famine feel to this stretch.
Tuesday the 25th is a write-off – small, sloppy, onshore junk. Nothing doing. Wednesday the 26th afternoon finally delivers: a 6-foot south swell with strong energy (567) and light offshore wind. That’s your first serious window. Clean, zippy lines will peel down the point.
Thursday morning the 27th is a keeper: 4-foot south swell with offshore breeze – smooth and ridable. Friday the 28th holds two proper sessions. Morning runs 5-foot swell, good period, clean offshore wind. The afternoon keeps it going, solid shape with clean faces.
The next few days are quiet, with a long flat spell starting Tuesday the 1st of September. Nothing worthwhile until Sunday the 6th.
That Sunday morning is the standout of the whole outlook. Glassy conditions – no wind at all. The swell is just over 5 feet out of the south. Even though the period is short, the energy is serious (475), and with an oily, flat ocean, Guillotines will turn on. Monday the 7th is similar: glassy again, smaller but longer period swell, making the paddle easier and the walls more drawn-out. Both mornings are golden.
Because it’s a spot that breaks infrequently under these conditions, you might have the place to yourself if you sneak in at dawn. But it can get crowded when it’s clean.
If you’re going to chase it, be on it Thursday 27th, Friday 28th, then don’t miss that Sunday 6th and Monday 7th glass. After that, things dribble away into small, weak leftovers.

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.
