The Lowdown

Alright, let’s break it down. Rusty here, and I’ve been looking at the charts for Suicide Cliffs. It’s a split forecast – a whole lot of ugly, then a taste of clean, then a proper monster.

Starting Monday, August 17th, we’ve got a weak 3ft groundswell from the SW ticking over at 8 seconds, but the cross-shore wind is just chopping it up. The water’s a warm 84°, which is pretty normal for the time of year. Through Tuesday and Wednesday the wind stays ugly, and the swell is either tiny or blown out. Thursday the 20th sees a jump in size – 8ft from the SE with a combined energy of 1100 – but it’s onshore and choppy, a real mess. By Friday the 21st, the swell is pumping up to 10ft to 12ft from the SSE, with energy readings over 1400, but again, the wind is onshore or cross-onshore, making it a washing machine. That’s kite-surfing conditions, not for a paddle.

The weekend stays rough. Saturday the 22nd and Sunday the 23rd keep the onshore flow with S and SW swell, but the quality is just poor. We’ve got a solid run of blank days here, about a week of nothing you’d want to paddle out for.

Then things start to turn. On Tuesday, August 25th, the wind finally swings offshore from the WNW, and we get a clean, small 3ft SW groundswell. It’s not big, but it’s clean. The energy is low (123), so it’s a longboard or a groveler, but at least it’s *surfable*. This little window of light, clean conditions carries through Wednesday the 26th and Thursday the 27th, with the swell staying around 3ft to 3ft and the wind holding cross-off or offshore. Thursday morning is the pick of this early window, with a clean 3ft from the W and offshore wind. It’s small, but it’s your only real chance for a few clean waves.

But the real standout, the one that’s got my heart racing, is the big one. On Tuesday, September 1st, we’re looking at an absolute beast of a groundswell from the SSE. We’re talking 38ft at 14 seconds – that’s a very long period, deep ocean energy. The combined energy reading is a jaw-dropping 48026, which is just insane. The wind is predicted to be a clean offshore breeze from the ENE. Now, here’s the thing: Suicide Cliffs is a reef break, and for a swell this size, it’s going to be a straight-up XXL, expert-only session. The file itself says it’s predicted to be too big for this break. This is not a wave for the faint of heart or for anyone without serious big-wave experience. If you’re a charger, you’re looking at the best swell of the year, but you’d better have your wits about you. For everyone else, stay on the beach and watch the show.

So, to sum it up: a long, grim gap of about a week, a few tiny, clean days in the middle, and then a world-class, dangerous, massive swell to finish. The only real standout is that September 1st bomb, but it’s a promise with a health warning.

Rusty.

Information about the Suicide Cliffs Surf forecast

The above surf forecast table for Suicide Cliffs provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Suicide Cliffs can be found by selecting the local surf guide option on the grey menu. Our Suicide Cliffs 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.

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 Suicide Cliffs 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.
