Alright folks, Rusty here. Let’s break down what’s coming up for Guillotines. It’s a slow start, but the second week has some serious gems. The first few days are a total loss, so don’t even think about it.

From the 12th through the 14th, it’s tiny and messy. We’re talking 0.6ft to 1ft of weak, cross-shore slop. Not worth a second look. The water temp is about 63°F, which is pretty standard for the season.

Then, Wednesday the 15th morning – that’s the big one. Guillotines will be pumping with a solid 10ft S swell, and a 12 mph offshore wind from the SW. The combined energy is massive at 2604, so there’s a ton of power. This is strictly for the advanced crew – it’s going to be a heavy, fast wave. The 8-second period is a bit short, but with that much juice and clean offshore wind, it’ll still be a proper session.

The 16th (Thursday) and 17th (Friday) are more manageable. Mornings have 5ft and 3ft respectively, with clean offshore winds. The combined energy drops to 373 and 159, so it’s more moderate, but still fun, clean lines.

The 18th (Saturday) afternoon picks up again – 5ft from the E with a 9-second period, light 6 mph cross-off wind. The combined energy is 353, so a solid, surfable swell. Sunday the 19th morning is another standout: 8ft of E swell, 12-second period, and glassy conditions with 3 mph wind from the west. That’s 1629 on the combined energy – a serious, long-period groundswell. On a point break like Guillotines, that’s a dream. Again, for the experienced only.

From the 20th onward, the size fades. The 21st (Tuesday) holds 5ft with clean cross-off winds, and the 22nd (Wednesday) morning is glassy with 5ft E swell. The 23rd and 24th keep the 3ft to 4ft range going with clean conditions. By the 25th, it’s down to 2ft, and the 26th and 27th are back to flat, tiny dribble.

So, the best of the best: Wednesday 15th July morning for the big, powerful 10ft bank, and Sunday 19th July morning for the glassy, 8ft groundswell. Both are for experts only. The 15th has the biggest size, the 19th has the cleanest, longest-period lines. Both are crackers.

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.
