The Lowdown
Alright, let’s get into it. The outlook for the next couple of weeks is a bit of a mixed bag. We’ve got a couple of windows that look good, but there’s also a long stretch of flat or poor conditions to work through.
First up, the standout is Friday morning the 28th of August at Guillotines (point break). We’re looking at a solid 5ft swell coming from the SSE with a period of 10 seconds. The combined energy is moderate at 544, so there’s a decent amount of push. The wind is light and offshore from the SSW, which will keep the waves clean. This is an advanced spot and it’s inconsistent, so don’t expect waves rolling through every few minutes, but when they come, they’ll be worth the wait. The swell direction isn’t bang on the optimum (SE), but it’s close enough to work. Crowds can be a thing here, so keep your eyes peeled. The water temp is about average for this time of year.
The afternoon of the same day drops off a bit, with the swell easing to 4ft and a cross-shore wind coming in, making things more marginal.
Saturday the 29th morning is glassy, with a clean 3ft swell from the SE. It’s surfable, but it’s ordinary – not going to blow your socks off. The energy is moderate at 259. The afternoon sees a cross-onshore wind come in, so it’s not worth hanging around for.
Sunday the 30th morning is another glassy one, with a smaller 3ft swell from the S. Energy is down to 147. It’s clean but small. The afternoon sees a 5ft pulse from the S with moderate energy (585), but the cross-shore wind messes it up.
Monday the 31st is back to small and glassy in the morning, with 3ft from the SSE, but it’s ordinary. The afternoon is a write-off with onshore wind.
Then we hit a big dry spell. From Tuesday the 1st of September right through to Saturday the 5th of September, it’s pretty much all poor or flat. The swell drops right off, down to 1ft to 2ft, and the wind is all over the place. There’s a bit of a pulse on Saturday afternoon the 5th, with 3ft from the SSE and a short period of 6 seconds, and offshore wind, but it’s weak and ordinary. The energy is low at 95. Honestly, the conditions look more interesting for kite surfing than paddle surfing during this stretch.
Sunday the 6th of September is still poor, with onshore winds and a messy 4ft swell.
Now, here’s the next good window. Monday morning the 7th of September is looking promising. We’ve got a 5ft swell from the S with a 10-second period, and offshore winds from the S at 6 mph. The combined energy is moderate to strong at 553. This is a repeat of the conditions from Friday the 28th, and it’s clean and surfable. Again, it’s an inconsistent spot, so be patient. The morning is the time to be on it, as the afternoon gets a cross-shore wind.
After that, it’s a slow decline through to the 12th. Tuesday the 8th morning is glassy with a 3ft swell from the S, but it’s ordinary. Wednesday the 9th is flat and glassy in the morning, then a 4ft onshore wind swell in the afternoon that’s poor. Thursday the 10th is the same story: glassy small waves in the morning, then a poor 5ft in the afternoon. Friday the 11th is glassy and small again, and Saturday the 12th is a write-off.
So, to sum it up: your best bets are Friday morning the 28th of August and Monday morning the 7th of September. The rest is mostly flat or poor, with a long gap from the 1st to the 5th of September where you might as well leave the board at home.

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.
