The Lowdown
Alright, let’s break it down in feet and knots. Rusty here, and I’m not going to sugarcoat it – this forecast is a dud. The only place to even talk about is La Guillotine, a sandbar that’s only for the advanced crew and is flat-out inconsistent. The water’s nice and warm, about 25°, a touch warmer than usual, but that’s the only good news.
We’re starting with a long gap. The first sign of anything is on the morning of Wednesday, August 26th, with a tiny 1ft wave from the SSE at a short 5-second period. The combined energy is just 18 – weak. The wind is a cross-offshore from the ENE at 9 mph, so it’s clean, but the waves are too small and poor. Don’t bother.
The rest of the week is the same. Thursday the 27th sees a bump to 4ft from the SE, still a short 5-second period, with moderate energy of 106. But it’s a cross-on wind from the SE at 12 mph, so it’s choppy and messy. Friday the 28th is the best of a bad lot, with a 3ft SSE swell, a 6-second period, and a clean NW cross-off breeze at 16 mph. Energy is 108, moderate, but still poor quality. It’s not a standout.
From Saturday the 29th of August all the way to the end of the forecast on the 10th of September, it’s flat. Tiny dribbles of 0.3ft to 1ft, with combined energy figures in the single digits. The wind is often clean, but there’s no swell to ride. A long, dry run.
So, there’s nothing here. La Guillotine is your only option, and it’s inconsistent. If you’re a kite surfer, the cleaner breezes with a little bump might be fun, but for a paddle surfer, this is a total loss.
Rusty.

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.
