The Lowdown
G’day, it’s Rusty here, giving you the long-range look at Scarecrows. We’ve got a solid run of south swell energy lining up over the next couple of weeks, but it’s not all clean, rideable waves. We’ll have to pick our windows wisely.
This is an exposed reef setup, and the water’s sitting at a warm 84°F with the temp anomaly only +0.5°F, so it’s about normal for this time of year, no dramas there.
The first real window we’ve got is Saturday the 12th. The swell is pushing 5ft from the southwest, but that southeast cross-offshore breeze is doing wonders for the surface. The combined energy reading is strong at 2297, and those long 19-second periods mean it’s proper groundswell, more power behind it. This is the standout of the first week. For a reef, this long period is perfect, and the conditions are listed as clean. It’s an advanced wave, so keep that in mind, but it’s the one to paddle out for.
Sunday the 13th sees a bit more size, 7ft, but the wind swings more southerly and the risk of thunderstorms is on the cards. It’s a bit messier, and Monday the 14th is similar: 6ft but with more cross-shore wind, so the surface won't be as crisp.
Tuesday the 15th morning is another good one. Dropping to 6ft from the SSW, and we’re back to that clean, cross-off wind. It’s another long-period swell, 15 seconds, and the energy is still moderate at 1254. Less powerful than Saturday, but the surface will be smooth.
The middle of the week gets a bit average. A lot of cross-shore winds and moderate chop with the swell dropping a touch. Nothing that’s gonna get you frothing until we hit Thursday the 17th morning. Swell is down to 4ft, and it’s a shorter period, but the wind is clean offshore. It’ll be a fun, smaller wave, but nothing serious.
After that, it’s a flat spell for a few days. Swell drops off, and we're looking at a bit of a lull with less energy and more sideways wind. Not the time to go out of your way.
Looking further out, Thursday the 24th morning is promising. The swell bumps back up to 6ft from the SSW, and with a light offshore breeze, conditions look clean again. It’s got decent energy at 1528, and periods of 16 seconds. That’s your second standout, but it’s well over a week away, so take it with a pinch of salt. Forecasts can shift.
And finally, Friday the 25th afternoon looks fun too. Swell 5ft from the south, 14-second period, and a light offshore wind. The energy is up there at 1812, and it’s listed as clean. Another nice one to keep in the back pocket, but again, it’s a long way out.
So, the pick of the lot for the next two weeks: Saturday the 12th morning is definitely the call for the bigger, cleaner power, and Thursday the 24th morning is the one to look forward to if you want some clean waves in the second week.
Now, that being said, there’s a lot of afternoons here that are only good if you’re hanging for a fight with chop and onshore wind. If the swell is up on those days and the wind is cross or onshore, this exposed reef will just be a mess, and frankly, it could be better for the kite surfers than the paddle surfers. Keep an eye on the wind and be ready to move when it’s right.
That’s it from me. Stay stoked, and I’ll see you in the water.

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.
