The Lowdown

Alright, this is Rusty, and I’m looking at the next couple of weeks for Guillotines. Straight up, it’s a frustrating run for a spot that can be a proper gem. We’re not looking at a classic outlook here. The swell just isn’t cooperating, and the wind is going to be a constant battle.

The first suggestion of anything surfable is the morning of Wednesday the 26th. The water is running a touch warmer than normal for this time of year, at 64°. We’ve got a small SSE swell sneaking in at 3ft, with a period of 8 seconds. The energy is moderate (137). The wind is a light SSE cross-offshore, which will keep the surface clean. It’s a point break, so that long period isn’t an issue, but it’s inconsistent, so you’ll be waiting for the sets. It’s surfable, but very ordinary. The crowd factor is there, so you might have company.

The next window is Thursday morning the 27th. Another glassy morning, with a similar 3ft ENE swell at 8 seconds. The energy is again moderate (129). It’s the same story: clean, small, and inconsistent. It’s a wave, but it’s not gonna get the heart pumping.

Then, Friday morning the 28th looks promising for the conditions. It’s dead calm, glassy as can be. The swell is 3ft from the ENE at 9 seconds, with moderate energy (135). It’s another one of those “surfable but very ordinary” mornings. If you’re desperate for a slide, that’s your best bet for the first week.

The second week looks a bit more energetic but still messy. The morning of Sunday the 30th has a glassy 2ft ENE swell, but the real change comes Sunday afternoon. A pulse of 4ft S swell hits, but with a strong 12 mph cross-onshore wind from the NE. The energy jumps to 438 (strong), but it’s going to be choppy and poor. Not worth it.

The standout, if you can call it that, is the morning of Monday the 31st. It’s glassy, with a 3ft S swell at 9 seconds, and the energy is moderate (243). It’s a clean, manageable wave at Guillotines, and the glassy conditions are a major positive. That’s probably the best looking window in the whole 16 days, but it’s still a long way out, so don’t bank on it.

After that, there’s a few more mornings the first week of September with clean conditions but tiny swell. The morning of Thursday the 3rd has a 2ft E swell and glassy, but it’s just not enough.

Honestly, for the whole 16 days, the swell is too small for Guillotines to really shine, and the wind is onshore or cross-shore for most of the afternoons. The best bet is the morning of the 31st of August, but it’s a long-range call. Keep an eye on it.

Rusty.

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.
