The Lowdown
Alright, Rusty here, let’s talk about Guillotines.
First off, the water temp is sitting at about 63°, which is pretty normal for this time of year. Nothing out of the ordinary there.
Now, looking at the next 16 days, it’s a pretty quiet start. We’ve got a long stretch of poor to marginal conditions through the first week. The morning of the 7th has a tiny 2ft SSE swell with a weak cross breeze, so it’s really not worth wetting a suit. The 8th morning goes glassy with a 1ft swell, but it’s just too small to get excited about.
The real standout is shaping up for the morning of the 22nd of August. That’s Saturday morning, and it’s got a solid 8ft S swell with a period of 8 seconds. The energy is strong (617), and the wind is glassy. That’s a rare combination at Guillotines. The swell direction from the south is right in the optimum zone for the spot, and with clean, glassy conditions, this is the best on offer. Keep in mind, this is a point break and it’s inconsistent, so expect long waits between sets. At 8ft, it’s definitely in the expert-only zone, so leave the foamies at home. Crowds are possible, so get there early.
The rest of the second week has some cleaner windows, like the 15th morning with a 4ft S swell and fresh offshore wind, and the 16th with a 4ft S swell and light offshore, but the size and quality don’t touch that 22nd morning window. The 20th and 21st have some decent-looking swell periods but the wind is onshore or cross-onshore, spoiling the shape.
So, bottom line: hold out for the morning of the 22nd. That’s your day.

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.
