The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s cooking for Guillotines.

First thing you need to know: this is an advanced, inconsistent point break that needs a very specific SE swell direction to really fire. So we’re not talking about a spot you can just rock up to any day. The next 16 days are a mixed bag, with a long stretch of flat or poor surf in the middle.

The first real glimmer of hope comes on Wednesday the 26th of August in the afternoon. We’ll see a pulse of 6ft S swell with a short 7-second period, but the combined wave energy is a very solid 599 (moderate to strong). The wind goes glassy, dead calm, and that’s a massive deal for a point break. The only worry is the short period, but if you’re there when it’s glassy, it could be a fun, punchy session. The water temp is about average for the time of year.

The next day, Thursday morning the 27th, still has some clean 4ft S swell (224 energy) with glassy conditions, but the waves are just ordinary. Not a standout but a good backup if you missed Wednesday.

Friday morning the 28th of August is the real winner. We’ve got a 3ft SSE groundswell with a long 11-second period, giving the waves shape and push. The combined energy is 328 (moderate), and the wind is dead calm—glassy as a mirror. The swell direction is SSE, which is a solid match for Guillotines’ optimum SE. This is the session to circle. Expect clean, lined-up waves for those who can handle the inconsistency and the advanced nature of the break. Crowds are possible, but on a Friday morning, you might get a few sets to yourself.

Saturday morning the 29th still has some clean 3ft SSE swell, but it’s weaker and very ordinary.

Then things go quiet. There’s a big gap from the 30th of August right through to the evening of Thursday the 4th of September. Very little surf, and what’s there is blown out or weak. A real dry spell.

Things finally look up again on Saturday the 5th of September. The morning delivers a 4ft SSE groundswell with a very long 14-second period. The combined energy hits 693 (strong), and it’s glassy. That’s a beautiful setup for a point break, with long, grunty lines. The crowds might be a factor since it’s a Saturday, but the quality could be the best of the whole forecast. The swell direction is SSE, right in the sweet spot. A bit of a caveat though: that long period can make it break a bit straight on a beach, but at a point like Guillotines, it’ll wrap in perfectly.

Tuesday morning the 8th of September closes the window with a 5ft NE swell (280 energy) and a moderate offshore wind from the SSW. That’s clean, but the swell direction is not ideal for Guillotines, and the height is getting into big territory for the spot. Could be a wild card for experts only.

The real standout? Friday morning the 28th of August and Saturday morning the 5th of September are the ones to bank on. The 5th looks more powerful, but the 28th is a bit closer and more reliable in the short term. Mark your calendar.

Rusty out.

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.
