The Lowdown
Alright, crew, Rusty here. Let’s be straight with you. We’ve got one spot on the radar for this whole stretch, and it’s a proper reef set-up that demands respect. We’re looking at a window that starts slow, builds to a solid pulse, and then backs off again.
The first few days are pretty average. Monday the 17th has some clean morning waves at 4ft from the SSW, but it’s just not holding together. The swell energy is weak to moderate at 724, and it’s not really lining up. We’re going to have to sit on our hands for a bit. The wind is a cross-offshore, which is nice for the surface, but the surf itself is marginal.
Tuesday and Wednesday see the swell start to push up. On the 18th, we’re looking at 7ft, then it jumps to 8ft on the 19th with the energy climbing into the strong zone (4176 and 4639). But the wind is cross or cross-on, with a chance of thunderstorms. It’s gonna be a bumpy, lumpy mess. Not worth paddling out for, even if you’re frothing.
Then things get interesting. Thursday the 20th is the standout of this first week. The swell holds at 8ft from the SSW, with a period of 16 seconds – that’s proper groundswell. The wind swings around to a light southeast cross-offshore, and the forecast is for clean conditions. This is where it pays to be an experienced surfer. The energy is strong at 3523, and this is the day to make the call. It’s still a big-wave reef, so this isn’t for the faint of heart or the weekend warrior.
The weekend fades out. Friday through Sunday (21st-23rd) drops back to 6-7ft, but the wind goes onshore and it gets chopped up. We lose that clean window. It’s just a lot of average, cross-shore slop.
The energy dips and the swell fades a bit early next week, but then it starts to come back. The 31st of August rolls around, and we see another standout on the horizon. Monday the 31st morning looks absolutely firing: 7ft of SSW swell with a 19-second period, light cross-offshore wind, and clean conditions. The energy is strong at 4130. It’s a long-period swell, which is perfect for this kind of reef break. This looks like the best wave of the entire window.
We should also mention the water temp. On that first Thursday, it’s reading 85°, which is about normal for this time of year.
So, the plan: sit tight, watch the buoys, and be ready for Thursday the 20th. And if you can wait it out, Monday the 31st is looking like a proper crown jewel, though it’s a week and a half out, so we’ll keep our fingers crossed.
Rusty out.

Information about the Scarecrows Surf forecast
The above surf forecast table for Scarecrows provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Scarecrows can be found by selecting the local surf guide option on the grey menu. Our Scarecrows 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 (Scarecrows) 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 Scarecrows 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.
