The Lowdown

Righto, let’s have a look at what’s cooking. The next few days are pretty quiet, but there’s a proper pulse of swell coming in the second week that’s got my attention. The water’s about 64°F right now, which is pretty normal for the time of year, nothing wild.

We’ve got a gap of a few days with hardly anything worth paddling out for. Saturday the 5th and Sunday the 6th are flat with rubbish wind, so don’t bother. Monday the 7th is a non-starter too. The first real glimmer is Tuesday the 8th morning at Guillotines – a point break that’s inconsistent and only for the advanced crew. It’s fair exposed to the south-east, which is the sweet spot. Tuesday morning sees a 4ft south swell, 9-second period, with offshore wind from the south. That’ll be clean, with moderate wave energy (438). It’s only 4ft, so not big, but with that offshore breeze it’ll be tidy. Just a heads up, crowds are possible here.

Wednesday the 9th morning is surfable but ordinary – 4ft south-south-east, 8 seconds, decent offshore wind but low energy (163). Not a standout.

Now, Thursday the 10th is where it starts to get interesting. Thursday morning is glassy, 6ft south swell, 10 seconds, strong energy (648). That’s a cracking combo for a point break – clean, lined up, and not too big. Thursday afternoon is even better: 6ft south, 11 seconds, 729 energy, with a cross-off breeze. That’s very good.

Friday the 11th morning is glassy again, 5ft south, 10 seconds, 536 energy – another solid morning session. The afternoon gets a bit cross-shore, but still decent.

The weekend of the 12th and 13th drops off again – small, choppy, not worth it. Monday the 14th is flat.

But hold onto your board – the real standout is rolling in from Wednesday the 16th. That morning, Guillotines gets a solid 10ft south swell, 11-second period, with offshore wind from the south-south-west. That’s huge energy (1809), and it’s excellent for experienced surfers. Over 8ft, so this is expert territory only. The point break setup will handle that long-period swell well, but it’s going to be heavy. Wednesday afternoon is even bigger at 13ft, 13 seconds, with a cross-off breeze – massive energy (4532), but marginal due to tide or conditions. Thursday the 17th morning stays solid at 12ft, 13 seconds, 3801 energy, clean with a cross-off breeze. Friday the 18th morning is 10ft, 13 seconds, offshore, 2802 energy – another excellent session for the experienced.

The swell eases by Saturday the 19th, with 5ft, 11 seconds, clean offshore wind – a good option for those who want a smaller, cleaner day.

The best of the whole run? Hands down Thursday the 10th through Friday the 11th for the clean, glassy, medium-size groundswell, and then the big stuff from Wednesday the 16th to Friday the 18th for the experts. If you’ve got the skills, that second week pulse is a proper event.

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.
