The Lowdown
Alright, Rusty here. Let’s talk about what’s shaping up at Guillotines.
Honestly, the next 16 days look pretty slim overall. There’s a lot of small, messy, or just poor conditions to wade through, and the real standout windows are few and far between. We’re looking at a couple of specific mornings where you might get a fun little session in if you’re patient.
The water is a touch warmer than normal for this time of year, about 64°F, so it’s comfortable.
The first real chance to get in the water comes on Wednesday afternoon, the 26th of August. Yeah, that’s a few days out. The swell picks up to a very clean 5ft from the S, with the combined wave energy jumping up to a solid moderate reading of 515. Winds are light and cross-off from the SSE, which will keep the face nice and clean. This is the best-looking window in the whole outlook—a decent little push of swell with good conditions. It’s an advanced point break that’s inconsistent, so don’t expect non-stop action, but when a set comes through, it’ll be worth it.
Early Thursday morning, the 27th, offers a smaller but glassy option. The swell drops to 4ft from the S with moderate energy (196), and with the wind going dead calm or glassy, the surface will be like a lake. It’s not going to be pumping, but for a calm, clean session on a small board, it’s a solid choice. That size is manageable for most.
Later on, early Friday morning the 28th of August has a tiny 2ft SSE swell with glassy conditions and no wind (0 mph), giving you a clean, micro-session with combined energy at 149. Also, Saturday morning the 29th looks very similar—3ft from the SSE, glassy, and clean, with energy around 152.
Further out, Thursday morning, September 3rd, has the biggest swell of the second week at 5ft from the SSE, but the period is short, only 6 seconds, and the wind is a light cross-onshore. It won’t be as clean as those earlier windows, and combined energy (203) is moderate, but it’s the best of a quiet end to the outlook.
Overall, Wednesday afternoon the 26th is the standout. The rest is small and glassy, or onshore and messy. There are long gaps—like the first few days and the middle of the second week—where there’s nothing worth paddling out for. If you’re desperate for a wave, those glassy mornings are your best bet.

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.
