The Lowdown

G’day, I’m Rusty. I’ve been lookin’ at the charts for Guillotines, and we’ve got a mixed bag headin’ our way over the next few weeks. This is a classic exposed point break that doesn’t fire all that often, but when it lines up, it’s a ripper. Water temp’s sittin’ at about 64°, a touch warmer than usual for this time of year – roughly one degree above average, so it’s a nice little bonus.

The action starts Monday September 7, with a glassy, clean morning. Swell is 4ft from the SSE with a short period of 8 seconds – not a ton of energy down there (261), but lookin’ alright for a sneaky session. By Monday arvo, the wind swings S at 12 mph, blowin’ offshore, and the swell jumps to 6ft from the SSE. The combined energy kicks up to 422, and conditions are lookin’ clean. That’s a solid start to the week.

Tuesday morning September 8 keeps the good run goin’ – clean, 6ft SSE swell, offshore wind from the SSW at 6 mph, energy up at 451. This is where it starts to get nice. Tuesday arvo though, the wind turns cross-on and it gets a bit choppy, so morning is the go.

Wednesday September 9 has another clean morning with 6ft SSE swell, S wind at 12 mph blowin’ offshore, energy at 323. But Wednesday arvo gets heavy – 10ft of S swell, howlin’ offshore at 25 mph, and the combined energy spikes to 1254. That’s a lot of power. This is advanced territory, boys – only for the experienced crew.

Thursday September 10 is the standout. Morning brings 8ft of S swell, clean offshore wind from the SSW at 12 mph, and a combined energy of 939. That’s proper point-break energy, and with SE bein’ the optimum direction here, this swell is aimed right. The waves will have some punch, and with that wind holdin’ offshore, it’s gonna be clean as a whistle. Friday morning September 11 is also worth a paddle – 6ft SSE swell, glassy conditions, SE wind at 3 mph, energy at 471. Nice and clean, but the Thursday session is the one to chase.

From Saturday September 12 through to Sunday September 20, it goes quiet. The swell drops off under 3ft, winds turn onshore or cross, and it’s pretty ordinary. There’s a whole gap of about 8 days with no real recommendations – a proper flat spell for Guillotines.

Then we get a flicker of hope on Tuesday September 15. Mornin’ shows 8ft S swell with offshore wind at 16 mph, energy at 719. That’s a decent bump, but the wind’s a bit strong, and by arvo it cleans up to 5ft. Wednesday September 16 has a clean 5ft SSE swell with light wind, but it’s not gonna blow your wetsuit off.

Further out, Tuesday September 22 sees a big 8ft S swell roll in, but it’s spoilt by onshore winds. It’s a week and a half away, so keep an eye on it, but don’t hold your breath.

The pick of the entire window is Thursday September 10 at Guillotines. That 8ft swell from the S, combined with clean offshore wind and a point break that just loves that direction – it’s gonna be the best day on offer. It’s inconsistent here, but when it happens, it’s gold. Snag it while you can.

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.
