The Lowdown
Right, listen up. Rusty here. Let’s have a look at what’s coming for Guillotines.
We’ve got a patchy run ahead. The first proper surf to talk about is this Friday, the 31st of July. The morning starts clean with a 5ft south swell, a light offshore wind and a combined energy of 411 (moderate). The water’s sitting at 63°, which is about average for this time of year. By Friday afternoon, it actually gets a bit better—swell bumps up to 6ft from the south, cross-off wind, and the energy jumps to 967 (moderate). That’s a solid session, and the standout of the first few days.
Saturday the 1st of August is a letdown. Morning has a 4ft SSE swell and clean offshore wind, but the energy is weak at 262 and the conditions are just ordinary. By afternoon, it’s a cross-on mess with a 5ft swell and short 8-second period—rubbish.
Sunday the 2nd and Monday the 3rd are total write-offs. Cross-onshore winds, choppy, and the swell drops off a cliff. On Monday morning, we’ve only got 2ft with 121 energy. That’s a gap of a few days with zero to recommend.
Tuesday the 4th and Wednesday the 5th of August bring a bit of hope. Wednesday morning has a clean 5ft south swell, cross-off wind, and 467 energy (moderate). Decent, but not a standout. Thursday the 6th through to Sunday the 9th are all poor to ordinary—small swells, cross-onshore winds, and energy levels below 100 most of the time. Another solid gap.
Then we hit the real standout. Friday the 14th of August afternoon. This is the one. A 13ft south swell with a 9-second period, clean offshore wind, and a massive combined energy of 2932 (very strong). That’s big, powerful, and clean. It’s only for experienced surfers—over 8ft is expert territory. Guillotines is a point break, so that moderate period groundswell will wrap in nicely. The south swell direction is a good match for the optimum SE direction in the guidance. This is the best on offer by a long shot.
Saturday the 15th of August morning is still big at 13ft, but the cross-onshore wind and choppy conditions make it a messy, heavy day. Not clean. The afternoon is a bit smaller at 10ft, but still cross-on. Only for experts, and not as good as the day before.
From the 11th onward, the energy is mostly weak and the swells small. The 14th is the clear winner.
The main highlight: Friday the 14th of August afternoon at Guillotines. That’s the session to circle. Big, clean, and powerful. It’s an inconsistent break, so when it fires like this, you grab it. Crowds are possible, so don’t sleep on it.

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.
