The Lowdown
Righto, Rusty here. Let’s have a look at what’s on the cards for Scarecrows over the next couple of weeks.
Alright, so we’re looking at a really solid run of surf coming up, but it’s not all plain sailing. The first few days are a bit of a write-off, with cross-shore winds and a messy chop making it hard to get a clean one. The water’s sitting at about 85°, which is pretty much bang on average for this time of year, so no surprises there.
The real action starts to build from Friday the 14th. That morning, we’ve got a south swell pushing 8ft, a long 16-second period, and the wind is swinging cross-offshore out of the southeast at 9 mph. That’s clean. The combined energy is pumping at 2692 and it’s only going to get better. Friday afternoon stays clean with the same cross-off breeze and a 7ft swell. This is for experienced surfers, no doubt – at 8ft, it’s solid, powerful, and the long period means it’ll be bowling nicely over the reef. You’ll want your wits about you.
Then Saturday the 15th morning is a standout. The swell drops to 5ft, but the wind drops right off to nearly nothing, just 3 mph from the southeast, cross-off. It’s glassy. The wave energy is still strong at 1578, and with that 14-second period, the shape will be beautiful. This is the pick of the first week – clean, punchy, and not too big for a confident intermediate. Crowds are possible at Scarecrows, so get in early.
We get a bit of a lull on Sunday and Monday with smaller swells, but still clean enough for a morning session.
Now, hold on, because the second week fires up. Tuesday the 18th afternoon sees a new SSW swell coming in at 5ft but with a massive 19-second period. The combined energy jumps to 3150, and the wind is light and cross-off. That’s proper groundswell, and it’ll be lining up like a freight train. Wednesday the 19th morning pushes the swell up to 8ft, with a 18-second period and cross-off winds at 12 mph. The energy is 3796 – that’s serious. This is expert territory only. Too big for most, but if you’ve got the nerve, it’s going to be a classic.
Saturday the 22nd morning is another one to circle. Swell back a touch to 8ft, still SSW, 16-second period, cross-off wind at 9 mph, and clean. The energy is 2629. It’s still a big wave, but the conditions are sorted.
The last few days of the outlook taper off a bit, but there are still clean mornings with chest-high sets on the 25th. Overall, the best of the best is that glassy Saturday morning on the 15th, and then the big, powerful groundswell from the 18th through the 22nd for the crew who can handle it.
Rusty, signing off.

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.
