The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for this stretch.
To be straight with you, right now there’s a big fat nothing for the next week. We’re looking at a solid drought from Wednesday the 9th all the way through to Monday the 21st of September. Day after day of clean, cross-off winds, but with zero swell to show for it. The water is sitting at a balmy 77°, which is a good 6° warmer than usual for this time of year – that’s pretty unusual and feels like a warm bath, but there’s just no energy in the water to get excited about.
The first real glimmer of hope doesn’t show up until Tuesday the 22nd of September. La Guillotine, a sandbar setup that’s advanced-only and rarely breaks, might finally see a pulse. On the Tuesday morning, we’ve got a moderate 5ft swell coming from the ESE, with a period of 7 seconds. That’s a short-period swell, so it’ll be a bit lumpy and lack the punch of a proper groundswell. The combined energy is moderate at 321, and with a clean cross-off wind from the WNW, it’ll look rideable. The swell direction is from the ESE, which is off the optimum S direction for this spot, so it won’t be lining up perfectly, but it’s the best we’ve got. Tuesday afternoon drops to 4ft with an offshore NNW wind, so it’ll be clean, but the energy drops off to 87.
After that, it’s pretty slim pickings. There’s a small window on Thursday the 24th of September, with a 4ft SE swell, an 8-second period, and moderate energy of 151. The wind is light and cross-off from the ENE in the morning, so it’ll be clean, but the swell is short-period and ordinary. The afternoon sees a cross-shore wind pick up, making it messy.
Honestly, nothing here is a standout. The best on offer is the Tuesday morning on the 22nd, but even that’s a “marginal” call at best. For a spot that’s inconsistent, it’s not exactly firing. If you’re desperate for a paddle, that’s your window, but keep expectations low.
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.
