The Lowdown
Alright, let’s get into it. I’m looking at the charts for this stretch and, honestly, it’s a tough run. We’re only looking at one spot here, Suicide Cliffs, a reef setup that’s very consistent and exposed to the SW. The water is sitting at 86°, which is a touch warmer than normal for this time of year, so at least the temperature’s nice.
Right off the bat, from Monday the 10th through Wednesday the 12th, it’s pretty rough. The surf is there, but the wind is a mess. Monday has a 8ft SW swell at 11 seconds with a cross-on SE breeze, so it’s choppy and blown out. The combined energy is strong though, hitting 1850. Still, the conditions are poor. Tuesday drops a bit to 5ft but the wind is still on it. Wednesday is a write-off with fresh onshore wind.
Then we get a little window. Thursday the 13th morning, the wind swings NW, light cross-off, and we see a 3ft S swell. It’s clean. The combined energy is weak at 202, but the quality is there for a small session. That trend holds through Friday the 14th. Friday morning is the real standout here. The swell bumps up to 4ft from the SSW, period at 8 seconds, and the wind is a light NE breeze, almost glassy. Combined energy is 267. It’s clean, it’s small but workable, and for Suicide Cliffs that’s about as good as this forecast gets.
From Saturday the 15th onward, it’s back to frustrating. The wind swings easterly, moderate to fresh, and the surf is small, mostly around 3ft to 5ft but with cross-shore chop ruining it. There’s a brief glimmer on Monday the 24th with a clean, cross-off morning, 4ft SSW swell, but the score is still marginal. The whole second week is a grind of poor conditions and small, messy surf. After the 25th, it just fades out.
Look, if you’re going to paddle out, aim for Friday the 14th. That’s the one morning where the stars align for a clean, small-wave reef session. The rest of the 16 days is either blown out or just too small to bother. It’s a quiet run, but forecasts can change.

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.
