The Lowdown
G’day, Rusty here. Let’s talk Suicide Cliffs. This spot lives for a south-west swell, and it’s fully open to it. The water’s a warm 84°F, which is about average for the time of year – no big anomaly.
Right off the bat, Thursday, September 3rd, brings a proper push of energy. You’ve got 5ft of swell from the south-west with a long 12-second period – that’s some real groundswell. The combined energy is sitting at 581, which is moderate, but for this reef, that period makes the waves stand up and peel. Thursday morning is the absolute standout. The wind is light offshore out of the north-northwest at 9 mph, and conditions are looking very good. It’ll be clean, with decent shape. Crowds are often a factor here, so make sure you’re in the water early.
Thursday afternoon the wind shifts cross-offshore from the west-northwest and bumps up to 16 mph, making it a bit more challenging but still doable.
From Friday, September 4th, right through to Monday, September 14th, the surf goes flat. We’re talking days of tiny swell, mostly under 2ft, with onshore and cross-onshore winds creating choppy, lumpy seas. There’s a brief moment on Saturday afternoon, September 5th, where it goes dead glassy with a light south-southeast breeze, and you might pick off a 4ft wave, but the energy is weak (375 combined). It’s not a real standout.
The flat spell is long – from the 7th to the 14th, wave heights drop to barely 1ft, and energy readings are down in the single digits and teens. That’s a long, quiet stretch. For a spot that’s very consistent, this is unusual, but it can happen.
Around September 16th and 17th, there is a slight bump from the northwest with heights around 3ft and energy in the 50s and 60s, but the wind is strong, cross, and cross-on, and periods are short at 7 to 8 seconds. It’s just messy and not worth your time. This setup looks more interesting for kite surfing than paddle surfing during that patch.
Your one and only real chance is Thursday morning, September 3rd. That’s the pick of the entire 16-day window.
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.
