The Lowdown
Alright, Rusty here. Let's have a look at what's shaping up for the next couple of weeks.
We're looking at a solid run of surf coming in, but it's not a straight-forward, flat-out green light for everyone. The standout period is the first few days, with a powerful, long-period groundswell rolling in. The water temp is about average for this time of year.
The main event kicks off on Thursday morning, the 27th of August, at Scarecrows (reef). This is a heavy, consistent, advanced reef break that's exposed to the swell. We've got a nice 4ft SSW swell pulsing with a very long 19-second period. The combined energy is strong (1674), and the wind is a light 6 mph cross-offshore from the SE. The word is "excellent surf conditions for experienced surfers," and that's no joke. This is the best of the bunch right here – clean, powerful lines. Be aware, crowds are possible, but for a wave this serious, it's usually the right crew out.
Friday morning, the 28th, keeps the quality high. The swell drops a touch to 6ft, still a long 16-second period from the SSW. Energy is still solid (1765), and the wind is a light cross-offshore again. Another excellent morning for experienced surfers. The swell is over 5ft, so it's getting into "too big for beginners" territory.
Saturday the 29th starts to see the swell ease, with morning winds picking up to a moderate 12 mph. The 4ft, 14-second swell is still clean, but the energy is dropping (817). Still a decent option for the right board.
From Sunday the 30th through to the 2nd of September, we see a mix of mornings with clean, cross-off winds and a fading but still fun SSW swell. The energy fluctuates, but the consistent light winds keep things tidy. The 31st of August Monday morning has a 5ft, 18-second swell with 1952 energy – that's a solid session hiding in there if you can get it early.
Then there's a bit of a reset. The 3rd and 4th of September bring a smaller, shorter-period swell. The 4th of September Friday morning is a special mention: glassy conditions with a 5ft SSW swell. That's a rare, clean window, but the period is down to 13 seconds, so it's less powerful.
The second week, from the 5th of September, is a mixed bag. You'll see some clean mornings with cross-off winds, but the swell is smaller and the energy is lower. The 7th of September Monday morning has a clean 3ft swell with a 14-second period – a good longboard morning. The 8th of September Tuesday is interesting: glassy conditions all day with a weak, short-period (7-8 second) SSE swell. Not much power, but it'll be fun on a twinny.
The 9th of September Wednesday morning is a real standout for the second week. A glassy, 3ft SSW swell with an 18-second period. That's a wave of energy (781) for its size. It'll be clean and lined up perfectly at the reef. This is a promising but less certain long-range call.
The last few days, the 10th and 11th of September, show a return of a cleaner, 4-5ft SSW swell with a 15-16 second period. The 11th of September Friday morning is another "excellent for experienced surfers" call, with light cross-offshore winds. This run has staying power.
So, to sum it up: the absolute best windows are Thursday morning the 27th and Friday morning the 28th of August. After that, keep an eye on the 4th and 9th of September mornings for those glassy, clean conditions. The rest of the time, there's always something to surf, but you'll need to pick your sessions.
Rusty.

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.
