The Lowdown
Alright, let’s break it down.
The next couple of weeks are a mixed bag. There’s a little to work with, but don’t clear your schedule just yet. The best swell is a long way off.
We start Thursday morning, August 13th, at Guillotines. This is a point break, so it handles direction well. It’s glassy with a 4.6ft south swell. The period is short at 8 seconds, so the waves will be a bit lumpy, but the combined wave energy is moderate at 380. Water temp is 63°, about average for the time of year. This is the best of the early days. It falls apart in the afternoon.
Friday the 14th is tiny and ordinary. The morning is glassy but the waves are only 2.6ft. Not worth it.
Saturday the 15th shows a bit of life. A 4.9ft south swell with offshore wind in the morning. The period is still short (6 seconds), but the energy is up to 217. The afternoon cleans up with a 4.6ft swell and a cross-offshore breeze. It’s surfable.
Sunday the 16th is small again, with a 2.3ft south swell. The morning is clean but weak (104 energy). Not much there.
The next week, from Monday the 17th through Wednesday the 26th of August, is mostly a write-off. The swell is tiny, winds are often onshore or cross-shore, and the energy is low. There are a couple of glassy mornings, but with waves barely over 2.6ft and weak energy, it’s flat for over a week.
Now, here’s the real one. On Thursday the 27th of August, the swell kicks hard. A 6.9ft south swell with a 10-second period rolls in. The wind is clean cross-offshore, and the combined wave energy rockets to 1634 – that’s strong. This is for experienced surfers only. The long period will mean longer waits between sets, but the point break at Guillotines will handle it beautifully. Friday the 28th is still solid with a 5.2ft south-southeast swell and offshore winds, but Thursday morning is the clear standout. Expect crowds at this spot because it’s the only real game in town.
For the kite surfers, the onshore and windy days from the 21st to the 26th might be more interesting than paddling.
Stay safe out there.

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.
