The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Guillotines over the next couple weeks.

Honestly, the 16-day window starts off pretty flat and ordinary. There’s a real quiet spell from Thursday through Saturday – tiny little bumps, maybe knee-high at best, with messy cross-shore winds and no real push. Wouldn’t even bother paddling out. The water temp is sittin’ around 63° with the anomaly runnin’ about 1° above average – feels pretty normal for early September, nothin’ wild.

Sunday the 6th shows a little more life. The Sunday morning session sees a clean 2ft swell from the south with a 12-second period, cross-off wind off the S, and a moderate energy reading of 215 – nothin’ huge, but it’s a start. That glassy Monday morning on the 7th is another decent look – 3ft from the SSE, 9-second period, total glass with a S light air, energy at 182. Clean, but still just average.

Now, Wednesday the 9th afternoon is where things start lookin’ interesting. That south swell pushes 4ft at 8 seconds, cross-off conditions from the SE, and the energy jumps to 385 – that moderate range, feels solid. The water’s still clean, and it’s the first real “good” recommendation. Then Thursday the 10th morning is straight-up glassy with 4ft from the SSE, 10-second period, energy 338 – that’s a tidy little window.

But the standout? Friday the 11th morning. Absolute glass, zero wind, 4ft from the south with an 11-second period – that long-period groundswell is a treat at a point break like Guillotines, will wrap in beautifully. Energy sits at 295, the whole scene’s clean. This is the best on offer, no question. Crowds are sometimes an issue here though, so get out early if you can.

Things fade again Saturday and Sunday with onshore junk, and then there’s a quiet gap until the next real bump.

Monday the 14th morning throws up a 6ft south swell at 9 seconds, energy 718 – strong intermediate energy. That 6ft is pushin’ heavy for beginners, more a spot for the advanced crew who know the reef. Problem is the cross-shore wind from the NW puts a little chop on the face – surfable but not clean.

After that it drops off again until Thursday the 17th afternoon – that’s the other standout. A 7ft south swell at 7 seconds, energy 753 – strong, but the period’s short, so it’ll be fat and a bit lumpy. However, the wind is offshore from the SW, only 6 mph, and the conditions are clean. This is a big, powerful wave for experienced surfers only – over 7ft gets serious quick.

Friday the 18th morning is a write-off – 8ft from the south but hammered by onshore wind at 16 mph, energy 1124, which is very strong, but it’s junk.

Overall, the best windows are Friday the 11th morning for the glassy groundswell perfection, and Thursday the 17th afternoon for the bigger, offshore, expert-level push. Everything else is either too small or too blown out.

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.
