The Lowdown

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

Alright, we’ve got a bit of a slow start, but things get real interesting. For the first few days the surf is either too big and messy or just plain small, so don’t get your hopes up just yet. The real standout is gonna be Thursday, September 10th at Guillotines. That’s the gem. You’ve got a solid 8 ft S swell, 9-second period groundswell, with clean offshore SSW wind at 12 mph. That’s a recipe for some proper, hollow waves for experienced surfers. The water temp is about 64°, which is a couple degrees warmer than normal for this time of year – not a big deal, but nice.

Now, on Friday, September 11th early, the swell drops to 5 ft with glassy conditions (3 mph ESE), but it’s a short period SSE swell, so it’ll be a bit weak. The combined energy is only 306, so not much punch. Still, it could be fun if you’re just looking for a clean, cruisy session.

After that, from Saturday the 12th right through to Monday the 15th, it’s a real dry spell. Mostly tiny, onshore slop or cross-off junk under 3 ft. Not worth paddling out for anyone who doesn’t own a foiler.

Then things start to build again. On Tuesday, September 15th into Wednesday, we get a steep rise. Tuesday afternoon sees a 7 ft S swell rolling in with 8-second period and 608 combined energy – not world class but clean with a light cross-off breeze. Then Friday, September 18th afternoon hits with a powerful 13 ft S swell, 9-second period, absolutely pumping at 2777 energy. That’s a big, powerful groundswell. The wind stays clean and cross-off, but that size is only for expert surfers. It will be too much for anyone who hasn’t been charging for a decade. Saturday the 19th is still roaring with a 10 ft S swell and 2735 energy, with clean offshore S wind at 9 mph. That is going to be a heavy, serious session.

After that, it fades fast into the second week. The rest of the forecast shows dropping swells and onshore winds, with little to get excited about. Overall, the big winner is the Thursday, September 10th window, and then the giant swell around September 18th-19th for the hardcore crew.

Remember, Guillotines is an advanced point break that’s inconsistent, so it doesn’t fire all the time. But when it does, and with this swell direction (SSE-optimum SE), it’s gonna line up. Crowds are possible there, so keep your head on a swivel.

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.
