The Lowdown

G’day, I’m Rusty. Let’s break down what’s cooking at Guillotines over the next couple of weeks. It’s a point break, so when it behaves, it’s a gem – but we’ve got a quiet start to push through.

Right now, it’s pretty dead. From Wednesday the 2nd through Saturday the 5th, there’s nothing doing – swell heights are tiny, winds are all over the place, and the wave energy is weak as, mostly below 100. That’s a four-day gap of nothing. Don’t bother waxing up.

Sunday the 6th morning shows a little life: swell around 3ft from the south, 8-second period, and wave energy at 163 (moderate). The wind is glassy – dead calm – so it’ll be clean, but the waves are ordinary. Not a write-off, but nothing to get excited about.

Monday the 7th morning keeps that glassy, clean vibe with a 3ft south swell and 9-second period. Energy is 176 (moderate). Still just surfable. But Monday afternoon sees the swell jump to 6ft from the northeast, though the period drops to 6 seconds – short-period junk. Energy is 305 (moderate), and the wind is light cross-off, keeping it clean. For a short window, it might offer a few fun ones.

Tuesday the 8th onward turns messy – onshore winds, chop, and poor conditions dominate through the rest of the week. Wednesday the 9th has strong offshore winds from the SSW at 22 mph, clean but with swell only 3ft – not enough push.

Now, Sunday the 13th morning is the standout. That morning we’ve got a 7ft south swell with an 8-second period, combined energy of 989 (strong). The wind is glassy – zero wind. That’s serious size for the point, and with clean conditions, it’s a session for experts only. Crowds are possible here – it gets busy sometimes, so get in early.

Monday the 14th is a letdown, but Tuesday the 15th morning brings a 6ft south-southeast swell with a 12-second period – a long-period groundswell with more shape and power. Energy is 1167 (very strong). The wind is light cross-off, so it’ll be clean. This is the other true standout: powerful, well-lined, and for strong intermediates or better. Again, crowds are possible.

Wednesday the 16th morning offers a smaller 4ft south-southeast swell, 11-second period, glassy, with 297 energy (moderate). Clean and fun for everyone.

So, the two best windows: Sunday the 13th morning (big, glassy, experts only) and Tuesday the 15th morning (powerful groundswell, clean, for the experienced). The rest is either flat or blown. Keep your eyes peeled – if that Sunday holds, it’ll be worth the wait.

Stay salty,
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.
