The Lowdown
G’day, it’s Rusty. I’ve looked over the next 16 days and honestly, mate, it’s a flat spell for Suicide Cliffs. There’s nothing on the board that’s worth paddling out for. The whole run is a grim stretch of tiny swell and poor surf conditions. We’re talking 16 days with no recommendable surf – just a long, quiet gap.
The only break on the radar is Suicide Cliffs, a reef setup that’s very consistent and exposed to SW swell. The water temp is sitting at 84°F, which is about normal for this time of year, so no surprises there.
Starting Tuesday 8th September, the swell is a pathetic 1ft from the S, with a short period of 8 seconds. The combined energy is only 37 (weak). Wind is offshore at 19 mph, so it’s clean, but there’s just no wave to ride. That’s the story all the way through to the end of the month. Wednesday 9th and Thursday 10th stay tiny, 1.0ft to 1ft, period dropping to 7 seconds, energy in the single digits to 39. It’s clean but flat.
Friday 11th gets messy with a cross-onshore wind and a 2-second period – basically a lake. Saturday 12th sees a slight bump to 4ft from the SE, period only 6 seconds, energy up to 132 (moderate), but the wind is cross-onshore at 16 mph, so it’s choppy and junk. Not worth it.
Sunday 13th and Monday 14th are clean but the swell is back to 3ft to 3ft, period 6 seconds, energy under 100. Nothing to write home about. From Tuesday 15th through to Wednesday 23rd September, it’s all 0.7ft to 1ft, periods between 5 and 10 seconds, and energy never above 37. Winds are mostly offshore or clean, but the swell is just too small. Even the longer period 9-second swells around the 15th and 16th can’t save it.
There’s no standout. No bigger swell, no good wind matching the optimum SW direction. It’s a write-off for paddle surfing. With the tiny swell and strong winds later in the period, this setup might look more interesting for kite surfing, but for normal surfing, it’s a hard no.
Keep an eye on the forecasts, but for now, take the boards off the car and have a beer.
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.
