The Lowdown

G’day, Rusty here. Let’s be straight up – Guillotines is our only option on the table for the next couple of weeks, and it’s a tricky one. It’s an advanced, inconsistent point break that needs a very specific SE swell to really fire, and for most of this run, we just aren’t getting it. There’s a long quiet stretch ahead, but things might just come together towards the very end.

Right now, we’re looking at a pretty flat start. Friday the 21st has tiny 2ft ENE windswell with a short period of 7 seconds, and a cross-shore breeze isn’t doing it any favours. Combined wave energy is weak at just 43. The water’s sitting at 64°, which is about 2° warmer than usual for this time of year – a little noticeable, but nothing wild. Saturday and Sunday stay small and messy, with hardly anything worth paddling out for.

Monday the 24th and Tuesday the 25th see a tiny bump in size, but the wind’s either onshore or cross-onshore, and the energy levels stay low. We’re talking 2ft to 3ft with weak to moderate energy (116 to 88). It’s a write-off for a decent wave.

Now, Wednesday the 26th finally gives us a little hope. Morning brings a gentle offshore from the south, with 2ft NE swell and 8-second period. Combined energy is still only moderate at 74, but the offshore wind will have it clean. The afternoon gets even better – a light offshore from the southwest, 3ft ENE swell, and energy up to 96. It’s only “surfable waves but very ordinary conditions,” so don’t expect perfection, but it’s the first window where you won’t be wasting your time.

Thursday the 27th looks clean but the wind picks up strong – 19 mph from the SSW offshore in the morning, with 3ft SSE swell. The energy jumps to moderate 165, but that wind strength is going to make it tricky, even if it’s offshore. The afternoon drops back in size and the wind turns cross-off, so maybe a session if you’re keen, but still nothing special.

Friday the 28th morning is glassy, with 2ft ENE swell and 8-second period. Energy is moderate at 152. It’s clean, but the swell’s small and the break is inconsistent, so you’ll be waiting around. The afternoon gets chopped up by a cross-onshore breeze.

The weekend of the 29th and 30th sees a jump in energy. Saturday the 29th afternoon has a 5ft S swell with a very short 6-second period, and energy hits moderate 224, but the cross-shore wind makes it lumpy. Sunday the 30th afternoon is the standout of this whole period. A 5ft ENE swell with 8-second period, a moderate offshore wind from the south, and combined energy of 340. The file says “expect good surf conditions” – that’s the one to circle. It’s still an inconsistent point, and 5ft is getting solid for advanced crew, but with clean offshore wind, it’ll be worth the paddle.

Monday the 31st has similar size at 5ft ENE, but the wind’s up to 25 mph from the SSE, which is a strong cross-off. Energy is very strong at 549, but that wind is going to make it a battle. Might be more of a kite day than a paddle day.

The first few days of September drop right back off. Tuesday the 1st is tiny again, and Wednesday the 2nd morning is glassy with a 1ft ENE swell but a long 11-second period. Energy is weak at 84. Clean, but barely a ripple.

Thursday the 3rd sees a 5ft NE swell with a short 7-second period, and cross-onshore wind. Energy is strong at 334, but it’s messy. Over 5ft and short period means it’s for experts only, and the wind’s no good.

Friday the 4th and Saturday the 5th are back to tiny, weak surf. Not worth the effort.

If I’m picking one true standout, it’s Sunday the 30th afternoon. Clean offshore wind, a solid 5ft ENE swell, and that energy reading of 340. The rest of the run is mostly waiting, but that window is real.

Stay tuned, forecasts can always shift. Rusty out.

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.
