The Lowdown
Alright, Rusty here again. Suicide Cliffs is in for a rough 16 days, and I’m not gonna sugarcoat it. The first days are a write-off, and there’s a long stretch of flatness before anything worth your time.
We start on Wednesday, September 3rd, with a 5ft swell from the SW, period around 12 seconds, and combined energy of 553—moderate. But there’s thunderstorms hanging around and a fresh cross-offshore breeze from the NNW. It’s clean enough to look at, but the surf is just marginal. Thursday afternoon (September 3rd) is the same: 5ft from the SW, 636 energy, but still dodgy with the weather and a strong cross-offshore wind. Not worth suiting up.
Then it’s a dry spell. From Friday, September 4th through to Monday, September 15th, the surf is mostly poor or tiny. Saturday, September 5th gives a little flash: 5ft from the SSW, 9-second period, and a clean offshore wind from the N. That’s a small window of clean, moderate energy (316), but it’s not a standout. The rest of the week drops to 2ft and under, with constant fresh winds. You’re better off doing something else.
The one real standout is a couple of weeks out. On Wednesday afternoon, September 16th, Suicide Cliffs gets a 4ft SSW swell with a very long period of 13 seconds, combined energy of 542, and a moderate offshore breeze from the N. That’s clean, lined-up groundswell—perfect for this reef. It’s the best day on offer, but it’s more than a week away, so stay hopeful but not certain.
Then Thursday morning, September 17th, brings a bigger one: 8ft from the S, period 12 seconds, and a massive 1615 combined energy—strong. That’s expert-only stuff, over 8ft, and the wind is only cross-offshore from the NW. It’s big and mean, marginal for most.
Water temp is about average for the season. Crowds at Suicide Cliffs are often, so you’ll have company on the good days. The long gap of nothing from the 4th to the 15th is a bummer, but that 16th and 17th are the only ones that’ll get your heart pumping.
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. 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.
