The Lowdown

Alright, let’s get into it. The next stretch looks like a bit of a waiting game before the ocean switches on. There’s a real gap for a few days here, so don’t be in a hurry if you’re looking to get wet. The first proper window shows up on Thursday the 10th, and that’s where you want to point your board.

For the first few days, it’s mostly small and average. Wednesday the 9th has some surfable waves at Guillotines, but the wind is going to mess with it, especially as the day goes on. The swell is only around `5ft` from the SSE with a short, weak `7` second period. The energy is weak at `264`; it’s just not doing much.

Then Thursday the 10th is your standout. The morning is looking clean with a light offshore wind from the S, and the swell has bumped up to `8ft` from the S with a `9` second period. The energy is strong at `1428`. This is real surf, but it’s in the advanced range—if you’re not comfortable, give it a miss. The afternoon holds up well, too, with the swell easing to `7ft`, but the period stretches to `11` seconds, and the wind goes light cross-off. This could be the best session of the run, with strong, clean lines.

Friday the 11th is another option, but it’s a step down. The morning has a glassy feel with only a `3 mph` easterly breeze, and the swell is around `4ft` from the SSE with a `9` second period. The energy drops to `308`, so it’s more mellow, but it could be fun if you want a cruise after the previous day.

After that, we hit a lull. From Saturday the 12th through to Tuesday the 15th, there’s nothing worth paddling out for. Swell drops below `3ft`, the winds get messy, and it’s mostly poor. That’s a solid four or five days of not much.

The next interesting pulse arrives on Tuesday afternoon the 15th. The swell jumps back to `7ft` from the S with a `9` second period and the energy is strong again at `1071`. The wind is a light cross-off, and it’s looking clean. This one is a bit further out, so keep an eye on it, but it’s promising.

After that, the ocean sort of goes quiet again for the rest of the window. There are some small pulses here and there, but nothing that gets the heart racing. The water temp is `63°F`, which is about right for this time of year, so a good wetsuit is all you need.

So, the take-away is clear: Thursday the 10th is your best bet, with Tuesday afternoon the 15th looking interesting if you’re willing to wait. It’s not a classic stretch, but there are a couple of proper windows if you time it right.

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.
