The Lowdown
Howdy, Rusty here again, lookin’ at Guillotines and trying to find some reason to get wet over the next couple weeks. Gotta be honest – it’s a slow story for a while, then one big event that steals the show.
Right off the bat, Thursday the 13th has a little waist-high swell – about 3ft of short-period south energy, glassy in the morning but weak, not much push. Afternoon gets a bit bumpy. Not worth it. Friday the 14th is even smaller – 3ft, clean but anemic. Saturday the 15th finally shows some life – 5ft of south swell with a solid offshore wind (12 mph), clean and decent energy. Still short-period, but at least it’s surfable. Sunday the 16th holds around 5ft, cross-off breeze, but light rain and less energy – alright, not great.
Then it just dies. From Monday the 17th through Tuesday the 25th, it’s mostly flat trash – tiny waves, weak energy readings in the low hundreds or less, and a lot of onshore crap. There’s a couple of days with some longer-period east-northeast swell (9-10s), but it’s only 2-3ft and messy. That’s a solid week of nothing – a real lull. If you’re a kiter, maybe the 23rd with its fresh cross-shore wind gets you out, but for a surfboard, save your energy.
Now the payoff. Wednesday the 26th – that’s the day. A proper swell rolls in: 7ft in the morning, pushing 8ft in the afternoon, with an 11-second period. The energy numbers go through the roof – 838 in the morning, then a huge 1596 in the afternoon. That’s serious power. Wind is offshore in the morning, stays clean with a cross-off in the afternoon. This is big, heavy surf – only for the experts. The point should handle it, but that long period can make it a bit lined-up and challenging. It’s a week and a half out, so treat it as a strong possibility, not a guarantee.
Thursday the 27th is still good – 4-5ft of south swell, 10s period, clean winds, energy around 368. That’s a great follow-up. Friday the 28th looks even cleaner – glassy morning, 4ft, 10s period, good energy (275). A nice way to end the run.
Water temp is about average for this time of year, nothing weird going on.
So, plan around the 26th if you’re advanced and ready for a proper session. The 27th and 28th are solid backups. The next week? Just sit tight, it’s flat.
Rusty signing off.

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.
