The Lowdown
Alright, Rusty here. Let's talk about what's brewing for this stretch, a bit of a mixed bag but with a couple of clear windows for something special.
Right off the bat, the standout and really the only spot worth locking in on is Guillotines. It's an inconsistent, advanced point break, so when it does fire, you need to know what you're doing. The overall set-up for the first few days is a bit of a slow burn, but patience will pay off.
We kick off on Tuesday the 15th with some rain and a modest 3ft S swell, but the wind is a cross-offshore, keeping it clean. It's surfable, but nothing to write home about. The real action starts building Wednesday the 16th. The swell jumps to 8ft from the S, with a period stretching to 9 seconds, and then 10 seconds in the afternoon. That's a solid groundswell feel. The combined energy is pumping, hitting over 1000 (1084) in the morning and peaking at a strong 1500 in the afternoon. With a fresh offshore wind all day, these are going to be clean, powerful lines. That 8ft is pushing into expert-only territory, so if you're not dialed in, just watch.
Thursday the 17th morning is the real gem. The swell drops to a still-chunky 6ft from the SSE, but the wind goes glassy. Absolutely dead calm. The period holds at 9 seconds, and the combined energy sits at a solid 515. This is where Guillotines really shows its colours – long, clean walls with no wind to mess them up. This is the best session on offer.
After that, things taper off. Friday the 18th still has a clean 3ft S swell with glassy conditions in the morning, but the energy is much weaker (237). The weekend of the 19th and 20th is tiny, with dropping swell and onshore winds. A bit of a flat spell.
Then there's a pulse on the 21st of September, with a 6ft SSE swell and a short 8-second period, but the wind is a moderate cross-offshore, so it stays clean. Energy is moderate (508). Not bad, but not the standout of the week prior. The morning of Tuesday the 22nd offers a smaller 4ft SSE groundswell (10-second period) with light offshore wind and clean waves, another nice window.
From the 23rd onwards, it's mostly poor conditions with onshore winds and a lot of weak, short-period windswell. The window between the 15th and the 22nd has the goods, with the 17th morning being the one to clear your schedule for. The water is typical for this time of year, nothing unusual to report there.
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.
