The Lowdown

Alright folks, Rusty here. Let’s have a look at the 16-day picture for Guillotines. It’s a slow start, but don’t write it off. The first couple of weeks are a bit of a mixed bag overall, but there’s a real standout waiting for you in the second week if you’ve got the patience and the skills.

We start off quiet. The first few days are pretty ordinary, with small, weak swell and a bit of chop. The real action doesn’t start to build until later. Water temp is sitting around 62°F, which is about average for this time of year, so no need for a thick wetsuit if you’re used to it.

The first real glimmer of something good is on Saturday, August 22nd in the afternoon. We get a pulse of 5ft swell from the S, with a period of 8 seconds. The wind is light and clean, coming from the SE as a cross-offshore. The combined energy jumps to 268 (moderate), and it’s starting to look clean. It’s not a massive standout, but it’s a sign that things are waking up.

Then Sunday, August 23rd, is where it gets interesting for a quick session. The morning brings a solid 6ft swell from the S, with a period of 10 seconds. The wind is virtually nothing, just a slight air, keeping it glassy clean. The combined energy is a healthy 641 (moderate to strong). This is a real nice window for a surfer who knows the wave. The swell direction from the S is a good match for Guillotines’ optimum SE swell. It’s a bit of a standout for the first week, but the real monster is coming.

Now, skip ahead to the real highlight. The absolute standout of the entire forecast is Tuesday, August 25th, in the morning. This is for experienced surfers only. We’re looking at a massive 12ft groundswell from the S, with a long period of 10 seconds. The combined energy reading is a whopping 4057 (very strong). The wind is glassy, dead calm, so the conditions will be as clean as it gets. This is a big, powerful, long-period groundswell. At a point break like Guillotines, that’s a recipe for some serious, well-shaped waves. The sets will be long, but the power will be there. This is the one to circle on your calendar. The wind does turn onshore in the afternoon, so get on it early.

The tail end of the forecast also has some clean, solid surf. Thursday, August 27th afternoon, and Friday, August 28th all day, offer 5ft to 5ft swell from the SE, with clean offshore to cross-offshore winds. The combined energy is in the 400-500 range (moderate to strong). It’s consistent and clean, making for a great end to the run.

Remember, Guillotines is an advanced, inconsistent point break. It rarely breaks, so when it does, it’s a special event. The crowds are possible, especially on the standout days. If you’re a beginner, anything over 5ft is going to be a challenge, and the 12ft day on the 25th is strictly for the experts.

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.
