The Lowdown

Hey everyone, Rusty here with a look at what’s coming up for Guillotines. At first glance, the next few days are pretty flat and uninspiring. We’re looking at a long run of small, weak swell and iffy winds that won’t get the blood pumping. It’s not until we get deep into the second week that things really start to look interesting.

Right now, and for the next several days, it’s going to be a struggle. The swell is tiny, mostly around 2 to 3 feet out of the southeast or south, with combined wave energy hanging around the low to mid 100s—barely any grunt in the water. Saturday morning (August 29th) offers a little something with a 3-foot SE swell and glassy conditions, but it’s really just ankle to knee-high and ordinary. We’ve got a spell of poor conditions through the rest of the weekend and into next week, with cross-onshore winds and choppy surfaces making it a write-off.

We hit a real dead zone after Wednesday the 2nd, with swell dropping to less than 1 foot and high winds. That lasts right through until Sunday the 6th when some rain showers push in and a new, bigger swell of about 4 feet from the northeast shows up, but it’s blowing 22 mph cross-shore, so it’s messy.

But hold on—the magic starts brewing overnight and into Monday morning, September 7th. We get a 4-foot NE swell with clean cross-offshore winds, and the energy jumps to 257. It’s still just ordinary surf, but the change is on the horizon.

Then, mark your calendar for Tuesday, September 8th morning. This is the standout. The southerly groundswell jumps to a solid 13 feet with a 10-second period, and the combined energy is a massive 3573—that is strong, powerful wave energy. The wind is glassy, and this is excellent surf for experienced surfers only. At that size, it’s a full-on expert zone. This is a classic point break setup, so it should hold that big, long-period energy beautifully, but average Joes and beginners should stay on the beach.

Later Tuesday afternoon turns ugly with a 15 mph cross-shore wind, so grab that morning window. Wednesday the 9th cleans up nicely with a strong offshore breeze from the southwest at 12 mph, welcoming a 5-foot SE swell for very good conditions. The swell stays in the 5 to 8-foot range through midweek, pushing 6 feet on Thursday with clean offshores – still great for the more experienced crew.

We finish the outlook on a nice note. Friday the 11th morning is looking tasty: 4-foot SSE swell, glassy offshore wind from the SW, clean conditions with wave energy of 332. Then Saturday the 12th afternoon brings a 4-foot SSE swell and a clean cross-offshore breeze—a good way to close it out.

A quick note on the water: it’s about average for the time of year, nothing too unusual. This break is inconsistent, but when it lights up like that Tuesday, it’s a true gem. Keep an eye on the forecast—if that wind holds, it’ll be a special morning.

Stay frothy,
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.
