The Lowdown

Righto, let’s talk about Guillotines. This is a point break that’s inconsistent, so it doesn’t fire all that often, but when it lines up, it’s for the advanced crew. The optimum swell direction is from the southeast, and it’s fairly exposed to that.

We’ve got a long stretch of nothing to start. From August 4th right through to the 10th, the surf is flat to tiny, with poor conditions. The winds are mostly cross-shore or onshore, and the wave energy is weak, often in the double digits (21 to 75). You’d be wasting your time paddling out.

The first real glimmer comes on the morning of Tuesday, August 11th. It’s glassy, with a 0.7 ft swell from the south at 7 seconds, but the energy is only 89 – it’s ordinary. The morning of Wednesday, August 12th is glassy again with a 2 ft east-northeast swell, but it’s the same story: weak.

Then things start to get interesting. On the morning of Thursday, August 13th, we get a clean offshore wind from the SSW, but the swell is still tiny at 1 ft. The afternoon, however, is where it kicks off. The swell jumps to 6 ft from the south, with a short period of 6 seconds, and the energy hits 323 – moderate. It’s clean, but that short period won’t give you much push.

Now, the standout. The morning of Friday, August 14th is a beauty. Offshore wind from the southwest, light breeze, and a clean 8 ft swell from the south-southeast at 8 seconds. The energy is 678 – strong. This is going to be a proper session for the experienced surfer. The afternoon stays solid with 8 ft and 8 seconds, but the wind swings cross-off.

But the real beast is Saturday, August 15th. The morning brings a 15 ft south-southeast swell with an 11-second period, and the energy is a massive 4150 – very strong wave energy. It’s clean with a light offshore. This is expert-only territory. The afternoon is just as huge, with 15 ft from the southeast at 12 seconds and 5435 energy. It’s still clean with a cross-off wind. If you’re not charging, stay out of the water.

Sunday, August 16th, the swell is still massive at 13 ft from the southeast, but the morning has onshore wind and the afternoon turns into a choppy mess with strong cross-onshore winds. The energy stays high (3397), but the quality drops.

Monday, August 17th, the swell drops to 8 ft from the east-southeast, but there’s a cross-shore wind with ripples, so it’s average. The energy is still strong (1104). Tuesday, August 18th, the wind goes clean offshore, with a 5 ft east-southeast swell at 10 seconds. The energy is moderate (525) and the conditions are good – a solid option for the advanced surfer.

Wednesday, August 19th, the wind is offshore again, but the swell is down to 4 ft from the east at 9 seconds, with energy of 253. It’s surfable, but ordinary.

So, the best on offer is absolutely the Saturday, August 15th session. That’s the big one. Huge, clean, powerful swell. Friday the 14th is a close second. Just remember, this break is inconsistent, so when it goes off, make the most of it.

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.
