The Lowdown

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

Right off the bat, we’ve got a pretty quiet start. The first few days are a bit of a write-off, with only small, weak energy showing. The water temp is sitting at 63°, which is pretty much bang on average for this time of year, so no drama there.

The real action starts to build on Sunday the 19th. We’ve got a pulse of groundswell from the ENE, 4ft, with a 12-second period. The combined energy is moderate at 514, but the real killer is the morning glass: NW wind at 3 mph, making it dead flat clean. That’s your standout morning for the week. The swell is a bit long for a beach break, but at a point like Guillotines, that long period energy will wrap in nicely. Crowds are possible here, so get in early.

The pulse pushes through Monday morning, still 5ft from the ENE, but the wind shifts cross-on from the N, making it less perfect. Afternoon gets a bit choppy with a 12 mph NE breeze. By Tuesday the 21st, we get another glassy morning, this time with a west wind, 4ft from the ENE, and moderate energy at 330. It’s not as punchy as Sunday, but clean and rideable.

Then we hit a bit of a lull mid-week. Wednesday and Thursday are small and messy, but hold on – Thursday the 23rd morning brings a solid 7ft pulse from the south, with a short 8-second period and offshore wind at 9 mph. That’s a lot of energy (552) but it’s a short-period wind swell, so it’ll be a bit bumpy and raw. This one’s for the experts only – 7ft is pushing it for most. The afternoon cleans up a bit, but drops to 4ft.

After that, the swell fades back into the doldrums for a solid week. From Friday the 24th through to the end of the month, there’s nothing worth paddling out for. Most days are under 3ft, with onshore winds or cross-shore junk. The energy drops right off into the double digits, and the wind is all over the shop.

There is a little flicker of hope on the 31st of July – a Friday morning with a 3ft, 12-second south swell, offshore wind, and heavy energy at 441. That’s a clean, long-period groundswell that will peel nicely at Guillotines. It’s a week and a half away, so don’t bank on it, but it’s a promising one to keep an eye on.

The first week of August looks like a total bust – strong onshore winds, rain, and small, messy surf. Not worth the wax.

So, the clear standout here is Sunday morning, the 19th of July. ESE 4ft, 12-second period, glassy conditions, and a moderate energy swell. If you can only paddle out once, that’s the window.

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.
