The Lowdown

Alright, folks, it’s Rusty here. Let’s break down the next 16 days for Guillotines, a point break that’s advanced-level and inconsistent. The first ten days are a real bummer. There’s almost no surf worth paddling for. The swell is tiny, barely 2ft to 2ft, and the wind is all wrong – cross-onshore or cross-shore chop messes it up. The combined wave energy is weak, often under 100 (63, 72, 88). The water temp is about 63°, which is average for this time of year, so nothing unusual there.

We get a little glimmer on Thursday, August 13th, in the morning. The swell picks up to 4ft from the south, with a period of 8 seconds, and the wind is light and variable from the NW at 5 km/h. The energy jumps to 322 (moderate). It’s only a marginal call, though, with a score of 1 out of 10, so don’t get too excited. By Friday, August 14th, the morning goes glassy – no wind at all – and the swell is 3ft from the south with a 10-second period. Energy is 141 (moderate). This is clean, but the waves are very ordinary. Still, it’s the best we’ve seen.

The weekend of August 15th and 16th offers some clean windows with light offshore or cross-off winds, but the swell stays small, around 3ft to 3ft, and the energy is only 106 to 130. It’s surfable, but you’ll be hunting for rides.

The real standouts are way out in the second week. On Sunday, August 23rd, we’ve got a promising window. The morning is glassy – no wind again – with a 4ft swell from the east-northeast, period of 10 seconds, and combined energy of 305 (moderate). This is the best on offer, with clean conditions and a decent push. The afternoon holds a 4ft swell from the same direction, 11-second period, and energy of 439 (moderate), but the wind shifts to a light cross-onshore, so you’ll want to be out early. This is a long-range call, so it’s promising but not set in stone. Keep an eye on it.

Overall, this is a rough start for Guillotines. It’s an inconsistent spot, and this run proves it. The first ten days are a waste. The only real chance is that Sunday, August 23rd, morning session. If you’re an advanced surfer and this point break is your style, that’s your time. Don’t expect crowds, as it’s only sometimes busy, but with the poor run, it might be empty.

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.
