The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a mixed bag ahead. The standout session is Thursday morning, August 27th, at Guillotines. That’s your best bet for this whole 16-day window, and it’s not even close. The rest of the forecast is a real struggle, with a long stretch of poor conditions after the first weekend. The water temp is sitting at 63°, which is about normal for this time of year, so no surprises there.
Thursday morning, August 27th, is the one to circle. Guillotines is a point break that’s inconsistent but when it lines up, it can be magic. We’ve got a 4ft S swell pushing in with an 8-second period, and the combined swell energy is moderate (280). The wind is glassy out of the SSW at just 3 mph, which means the surface will be smooth as a mirror. The swell direction is SE, which is right in the sweet spot for this spot. The waves will be a bit short-period, so they won’t have that deep groundswell push, but for a point break, it’ll still offer some fun, clean lines. It’s advanced-level territory, and crowds are sometimes an issue, so get out early if you can.
Thursday afternoon, the wind swings ESE and gets cross, making things messy. It’s a quick window.
Friday morning, August 28th, brings a pulse of 5ft SSE swell with a 10-second period, and the combined energy jumps to strong (544). The wind is offshore from the SSW at 6 mph, so the waves will be clean. That’s a solid option, but the swell is pushing above 5ft, so it’s pushing into the “too big for beginners” zone. It’s still a good look for the advanced crew. The swell direction is SSE, which is a bit off the optimum SE, but it’ll still wrap in nicely. The afternoon turns cross and drops off.
Saturday morning, August 29th, it drops to 3ft SE swell, glassy wind, but the energy is moderate (266) and the conditions are just “ordinary.” Not terrible, but not a standout.
Then we hit the wall. From Saturday afternoon onward, through the rest of the 16 days, it’s a long, bleak run. Sunday, August 30th, through to Friday, September 11th, the swell barely cracks 3ft, and most days are a mix of cross-on, onshore, or just flat. The combined energy drops to weak (under 100) for many days, and the wind is often a problem. Even the glassy mornings, like Sunday and Monday, only offer tiny, weak waves. The second week, from September 3rd onward, is almost entirely flat or choppy. There’s nothing worth paddling out for after the first weekend.
If you’re a kite surfer, some of those windy afternoons later in the period might look interesting, but for a paddle surfer, it’s a write-off after August 29th.
Bottom line: Thursday morning, August 27th, is your golden ticket. Try to get on it. After that, it’s a long wait for the next pulse.
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.
