The Lowdown
Alright, surfers, Rusty here. Let's talk about what we've got cookin' over the next couple of weeks.
Right off the bat, I gotta be straight with ya: it's a rough start. We're looking at a run of pretty average to downright ugly conditions for quite a while. The first real chance to wet a line doesn't pop up until Tuesday the 25th, and even then, it's only just barely surfable. We're talkin' about a solid five-day gap with no real recommendations before that.
The standout window, and I mean the *real* standout, is looking like the end of the first week and into the second. We've got a big pulse of SW groundswell expected, and for a little while there, the wind might play ball.
Let's break it down.
The first few days (Friday 21st through Monday 24th) are a write-off. Big, messy, windy swells from the south-east with onshore and cross-onshore winds. The wave energy is all over the place, from a moderate 856 up to a powerful 2273, but it's all blown out and lumpy. Don't even think about it.
Tuesday the 25th is our first glimmer. The swell drops right down to a tiny 4ft from the SW, but the real story is the wind. Tuesday morning is a cross-off breeze, but Tuesday afternoon... we get *glassy* conditions. The wave energy is weak at 176, but for a few hours, it might be clean enough for a longboard. It's not gonna be epic, just a chance to get a few small ones.
Wednesday and Thursday the 26th and 27th see the swell start to build again. Wednesday is messy with cross-shore winds, but Thursday the 27th is where it gets interesting. The swell is up around 8ft from the west, with a clean, offshore breeze. The wave energy jumps right up to a strong 1734 and then 2188 Thursday afternoon. This is where you want to be paying attention.
Suicide Cliffs – the whole forecast is for this one spot. It's a reef break, very consistent, and it's exposed to the SW, which is exactly what's coming. For Thursday the 27th, we've got 8ft of W swell with a clean cross-offshore breeze, and the period is up to 12 seconds on the afternoon. This is going to be lined up and clean. The water temp is about 84°, which is dead average for this time of year, so it'll be a warm one.
Now, into Friday the 28th, the swell gets bigger. We're talking 12ft from the SW, and the period is a solid 11 seconds. The wind is still offshore, but it's getting strong – up to 25 mph in the afternoon. The wave energy is massive, hitting 2744. This is for experts only. It's going to be powerful, and at that size, a reef break like Suicide Cliffs demands respect. It's the biggest, cleanest stuff of the forecast, but only for those with the skill to handle it.
After that, things drop off again. Saturday the 29th through to the end of the second week, it's back to small, onshore, and choppy conditions. The last little blip is around Friday the 4th and Saturday the 5th of September, where we see another pulse of swell – 8ft from the SE with a very long period of 13 seconds. The wind for that one is messy, but there's a chance for clean conditions early on the 5th. It's a long way out, so take it with a grain of salt, but it’s the only thing on the horizon for that second week.
So, to keep it simple: the best bet is Thursday the 27th at Suicide Cliffs. It's the cleanest combination of a good-sized swell and decent offshore wind. Friday the 28th is the biggest, but it's a beast for the brave. Don't bother before Tuesday the 25th.
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.

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.
