The Lowdown
Alright, grab your wettie. Rusty here, and I’ve been staring at the charts for Guillotines. Let’s be real — the next week and a half looks pretty average, but there’s a light at the end of the tunnel if you're willing to wait.
Right now, we’ve got a bit of a flat spell kicking off. The first real chance of a wave is Saturday afternoon, August 15th, but it’s nothing to write home about. You’re looking at a weak 4 ft swell rolling in from the south, with a short 6-second period. The combined energy is only moderate (218), and while it’s clean with a light cross-off breeze, it’s just surfable, not special.
Sunday morning, August 16th, drops off even more — clean and glassy, sure, but the swell’s down to 3 ft from the ESE. The afternoon gets interesting in period, with a 2 ft south swell jumping to 11 seconds (a bit of a longer period), but the wave energy is still modest (175). The water temp is sitting at 62°F, which is about average for this time of year — nothing out of the ordinary.
Then we hit a real dry patch. From Monday the 17th all the way through to Tuesday the 25th, there’s almost nothing worth paddling out for. Swells are tiny, periods are short, and the wind is mostly onshore or cross-shore junk. There are a couple of clean, offshore mornings in there (like the 24th and 25th), but the swell is barely 1 ft — you’d need a longboard and a lot of patience.
But hold on. Tuesday afternoon, August 25th, we get a flicker of life. A south swell jumps to 6 ft with a 6-second period, and the energy ramps up to 305 (moderate). It’s clean with a cross-off breeze, but it’s still a bit raw.
The real standout is Wednesday morning, August 26th. This is where it gets serious. We’ve got a solid 10 ft south swell with a 9-second period, and the energy is very strong (1410). The wind is glassy — dead calm. This is proper surf, but at this size it’s for experienced surfers only. By afternoon, it’s up to 13 ft from the SSE, 10-second period, and the energy hits 3204. Clean and light cross-off winds. This is the start of something big.
Thursday the 27th is the peak for the hardcore crew. Morning brings a 15 ft SSE swell, 11-second period, and the energy is massive — 4667. Light offshore winds from the south, clean faces. This is big and powerful. Experts only.
But if you want THE session of the forecast, circle Friday morning, August 28th. Guillotines is an inconsistent point break, but when it fires, it’s world-class. That morning, we’re looking at a 16 ft SSE groundswell with a very long 12-second period. The combined energy is insane — 13,113. Glassy conditions, no wind. This is the kind of day that makes you remember why you surf. If you’re not an expert, stay on the beach. For those who are, it’s a life changer. The swell direction (SSE) is also close to the optimum SE direction for this spot, so it should line up beautifully.
By Saturday the 29th, it’s still solid — 10 ft from the SE, long period, glassy morning — but the energy is dropping. Still excellent for experienced surfers.
So, the takeaway? The first 10 days are a write-off. Don’t bother. Save your energy for that Wednesday the 26th through Friday the 28th stretch. Friday morning, August 28th, is the absolute standout. Expect crowds — it’s a known spot and it’ll be busy with everyone sniffing that swell. But if you’re in the water early, you’ll score.
Stay patient. Stay salty.

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.
