The Lowdown

G’day, Rusty here. We’ve got a mixed bag coming in for Guillotines over the next couple of weeks—some real gems in the second week, but the first few days are a bit of a write-off. Let’s break it down.

The swell kicks off on Thursday the 30th of July with a 4ft swell from the south at 8 seconds. The wind’s a cross-off from the WSW at 6 mph, so it’s clean, but the energy’s only moderate at 192, and conditions are pretty ordinary. Thursday arvo jumps to 6ft from the south with an 11-second period and moderate energy of 748, but the wind swings cross-off from the SSE at 9 mph, and it’s marginal. Not worth paddling out for.

Friday the 31st is a step up. Morning glassy conditions with a 5ft south swell, 10-second period, light offshore from the SW at 3 mph, and clean surf. Energy’s 423—moderate. That’s a decent session. Friday arvo goes 6ft from the south, 9-second period, but wind picks up to 9 mph cross-off from the SSE. Energy jumps to 1047 (strong), but the score’s only okay. Better than Thursday, but not a standout.

Saturday the 1st of August morning is where it gets interesting. Glassy conditions, light offshore from the SW at 3 mph, and a 5ft swell from the SSE at 9 seconds. Energy’s moderate at 373. That morning looks clean and fun—one of the better early windows. Saturday arvo goes cross-on from the ENE, so it’s a write-off.

Sunday the 2nd is poor all day, with onshore winds and dropping energy. Monday the 3rd and Tuesday the 4th are flat and ugly—1ft to 2ft with no energy. That’s a solid 4-day hole. Things pick up again from Wednesday the 5th arvo with a 6ft south swell, 9-second period, and moderate energy of 809, but the wind’s moderate from the SSE. It’s marginal but surfable.

Now for the real standouts. Saturday the 9th of August: morning has a 6ft swell from the NE at just 6 seconds—short period, so it’s going to be a bit wonky. But the arvo session shows a 6ft swell from the NE with clean, cross-off winds from the SSE at 6 mph, and moderate energy of 378. Not huge, but clean.

The true highlight lands on Tuesday the 11th August. Morning has a 6ft swell from the ESE at 11 seconds—long period groundswell—with gentle offshore from the SW at 9 mph, and energy of 658 (moderate). That’s got shape and power. But Tuesday arvo is the pick: 7ft from the ESE, 10-second period, clean with light cross-off from the SSE at 6 mph, and energy of 748 (strong). That’s a solid session for advanced surfers. Wednesday the 12th is also good: 6ft to 6ft swells from the east, 10-second period, clean with light winds.

Thursday the 13th arvo sees an 8ft swell from the SSE at 9 seconds, with clean cross-off winds from the SE at 6 mph, and strong energy of 1128. That’s getting big—only for experts. The water temp is about average for the time of year (no anomaly flagged), so no surprises there. Crowds at Guillotines can pop up sometimes, so expect company on the good days.

Bottom line: the best windows are Friday the 31st morning, Saturday the 1st morning, and especially Tuesday the 11th and Wednesday the 12th. The second week holds the real power and clean conditions. Keep an eye on the long-range—still a bit out, but promising.

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.
