The Lowdown

G'day, Rusty here. Let's have a look at what's on offer.

We're kicking off Saturday the 29th of August with small swell and poor conditions, so it's a bit of a slow start. The water temperature is sitting at 62°F with a 0.4°F anomaly, which is about average for the time of year – nothing out of the ordinary.

The first real chance to get wet comes Sunday morning the 30th, with glassy conditions at Guillotines. The swell is small, around 3ft from the south, and it's a point break that's inconsistent, but for a few hours the wind is dead calm – that's glass. The energy is weak (145) and the period is short at 9 seconds, so it's not going to blow your socks off, but it's surfable and clean. If you're desperate for a paddle, that's your window.

From Sunday afternoon right through to Tuesday the 8th of September, it's a pretty lean stretch. The swell stays tiny, the wind is mostly cross or cross-onshore, and the energy drops into the double digits. There's a long gap of about 10 days where conditions are just ordinary or poor. A couple of mornings show clean lines, like Monday the 31st morning with a light cross-off, but the swell is only 3ft and the energy is weak – it's not worth getting excited about.

Now, the standout. Wednesday the 9th of September – that's the one to circle. The morning sees a solid 10ft swell from the south, with a period of 10 seconds and a massive energy reading of 2497. That's a strong pulse of energy. The wind is light and cross-off from the SSE, keeping the surf clean. But listen, this is a serious step up – 10ft is well into the expert-only zone. Guillotines is a point break and inconsistent, so when it's on, it's on, but you need to know what you're doing. The optimum swell direction is SE, and this is coming from the south, so it's a bit off the ideal, but for a point break, a south swell can still wrap in nicely. The morning is class, but by afternoon the wind swings onshore and kills it.

Thursday the 10th of September morning is another look – glassy again with a 5ft south swell, period of 11 seconds, and moderate energy (524). That's more manageable for intermediates, and with the wind dead calm, it's clean. But the afternoon is a write-off.

After that, the swell backs off through the second week. Friday the 11th and Saturday the 12th mornings have small, clean surf with offshore winds, but the swell is under 5ft and the energy is low. It's not a bust, but it's not a highlight either.

Bottom line: the first week is a washout, then Wednesday the 9th of September morning is the big one for experts. Thursday the 10th morning is your best bet for the rest of us. The second week fades out into small, average conditions.

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.
