The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for La Guillotine.
To be straight with you, this is a tough outlook. We’ve got a long stretch of nothing at the start. From Wednesday the 12th right through until the morning of Friday the 22nd of August, there’s barely a ripple to get excited about. The swell energy is totally flat, with combined energy at zero or just a couple of points (1–3) from tiny, short-period pulses. The wind is mostly offshore or cross-offshore, which is nice, but without any swell to work with, it’s just a pretty lake. This is a real dry spell for the sandbar.
The first real sign of life shows up on the morning of Saturday the 22nd of August. We get a tiny SSE swell at 1ft with a period of 5 seconds, pushing the combined energy all the way up to a whopping 7. It’s still poor surf conditions, but it’s something. The morning starts with a light cross-offshore breeze from the WNW, so the surface will be clean. By the afternoon, the wind swings SW and goes cross-onshore, messing with the shape.
Then, on Monday the 24th of August, we see a little more energy. The morning swell is 1.0ft from the SSE, but the period bumps up to 7 seconds, giving us a combined energy of 10. The wind is a moderate cross-shore from the W at 15 mph, which will be choppy and not great. The afternoon cleans up with a WNW cross-offshore wind, but the swell is even smaller at 0.7ft.
After that, the forecast drops off again into a flat spell with strong winds, so no real surf on offer.
The water temperature is a notable 78°F, which is 4°F warmer than normal for this time of year – that’s a solid anomaly, so you’ll be surfing in bathwater if you get in.
The best on offer? Honestly, there’s no standout here. The morning of Saturday the 22nd of August and the afternoon of Monday the 24th of August are the only windows with a clean surface and a few pulses of energy, but it’s tiny and weak. If you’re desperate for a paddle, those are your windows. For anyone looking for a proper wave, this is a waiting game.
Rusty, signing off.

Information about the La Guillotine Surf forecast
The above surf forecast table for La Guillotine provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at La Guillotine can be found by selecting the local surf guide option on the grey menu. Our La Guillotine 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 (La Guillotine) 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 La Guillotine 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.
