The Lowdown
Alright folks, let’s get into it. Rusty here, and I’ve gotta be straight with you right from the start – the next week and a half is looking pretty grim for Suicide Cliffs. We’ve got a long stretch of poor conditions ahead before things finally start to show some promise.
The first solid recommendation doesn’t roll around until Tuesday the 28th of July, and even then, it’s a bit of a mixed bag. For the first week, from Tuesday the 21st right through to Monday the 27th, you’re looking at tiny, weak swell with poor surf quality. The combined wave energy is barely a whisper, maxing out at 94 (weak energy) on the 25th. Winds are mostly cross or cross-on, keeping the surface messy. There’s a moment of glass on Thursday the 23rd, but the swell is so small (1ft) it’s barely worth a paddle. This is a long stretch of nothing.
Now, the real story starts to change around Tuesday the 28th of July. A significant swell is forecast to push in, with a solid 15ft from the S with a 13-second period, giving the break a very strong wave energy (6180). This is a big, powerful groundswell, but it’s coming in with cross-shore winds, so the surface will be a bit choppy. The water temp is about average for this time of year, so nothing wild there. This is really only for the experienced crew; 15ft is well into expert-only territory. The conditions are rated as marginal, but the size is undeniable.
The standout period, and the one to circle on your calendar, is the morning of Friday the 31st of July. We’ve got a 4ft S swell (8-second period, so a short-period windswell) but the real winner is the wind: true offshore from the NNW at 9 mph. That’s going to clean the place up beautifully. The combined energy comes in at a moderate 387. It’s not the biggest, but for Suicide Cliffs, clean offshore winds are a major positive. This is your best bet for a fun, uncrowded session, though with it being a consistent spot, you might see a few others out.
After that, the first week of August looks like a write-off. The wind is going to be howling, with a near-gale on Sunday the 2nd and then a violent storm on Monday the 3rd, making it completely unsurfable.
So, the plan is simple: wait for the 28th if you’re an expert chasing big swell, but for the best all-round clean conditions, hold out for the morning of the 31st. That’s your 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. 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.
