The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Suicide Cliffs. It’s a pretty quiet start to the outlook period, with the first few days shaping up as a write-off despite some small swell in the water.
Overall Pattern
We’ve got a long stretch of poor conditions kicking things off. There’s a real lack of decent surf for the first nine days. A couple of mornings around the 5th and 7th September offer clean windows, but the wave heights are really only just picking up to a marginal state. The real standout action is way out in the second week, with a big pulse of swell arriving around the 15th. That’s a long-range call, so keep your expectations in check, but the early signs are massive.
Day by Day
The stretch from Tuesday the 1st through to Monday the 7th September is mostly one to sit out. Fresh winds up to 22 mph and cross-shore conditions tear up the wave faces. The combined swell energy is pathetic to start, reading just 98 on the 1st, a sign of how weak things are.
There is a brief glimmer on the morning of Saturday the 5th September. The wind drops to glassy, and the swell bumps to 5.6 ft from the SSW with a period of 9 seconds. The combined energy climbs to 439. It’s surfable, but it’s not pure quality, and the afternoon looks better with a cleaner 5.9 ft swell out of the SW and energy jumping to 878. Still, it’s only a brief moment before the wind gets up again.
Monday the 7th September morning is another clean window. You’ve got 5.9 ft from the SSW with a 9-second period, combined energy of 488, and a cross-off breeze. It’s okay, but nothing to write home about. After that, the wind cranks back up and the surf quality tanks again right through until the 11th.
The Big Standout
Now, if you’re an experienced surfer, Thursday the 11th September starts to show some signs of life, but the real event is Tuesday the 15th and Wednesday the 16th. This is where it gets serious. The morning of the 15th brings a solid 13.1 ft swell from the south with a very long period of 16 seconds. The combined energy is massive at 8434. The wind is offshore from the north at 16 mph, setting up clean, powerful lines. This is a proper groundswell, and for a reef break like Suicide Cliffs, that long period and direction means it’ll focus a ton of energy. The swell is over 8 ft, so this is strictly for experts.
The following morning, Wednesday the 16th September, sees the biggest swell of the whole run: 18 ft from the SE with a 14-second period and combined energy hitting 11385. It’s another offshore morning with winds from the NNE at 16 mph. Again, experts only. This is a rare, powerful event, but it’s a long way out, so don’t get your hopes up just yet. The swell direction of SE is not the optimum SW for Suicide Cliffs, so it may not hold as well as the south swells.
Kite Surfing Note
For the first nine days, with the persistent fresh wind and clean, bumpy waves, if you’ve got a kite, you might have more fun than a paddle surfer.
Stay safe out there.

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. If you surf the same spot (Suicide Cliffs) 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 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.
