The Lowdown
Alright, Rusty here, taking a look at the full picture.
Scarecrows is the only game in town, and it’s a reliable, advanced reef break that loves a good SSW groundswell. The whole 16-day window has surf on offer, so no quiet spells to worry about. Water temps are 85°, which is normal for the season.
The first week starts off a little lumpy. Tuesday the 18th brings some 7-foot SSW swell with a long 16-second period, but the wind is a cross-shore SSE breeze at 12 mph, so it’ll be choppy. Combined energy is strong at 2372, but the conditions are just marginal. Wednesday the 19th is where the height peaks, with 8-foot in the morning and 10-foot in the afternoon, riding on a very long 18 and 17-second period. That’s a lot of water moving. Energy is over 4000 – really powerful. But it’s still cross-shore, so it’s raw, heavy, and only for experts. It’s not the top pick though.
The real standout, the one you want to circle on the calendar, runs from Sunday the 30th through Tuesday the 1st of September. Sunday morning gives us 5-foot of SW groundswell with a fantastic 17-second period. The wind turns light and offshore from the SE at just 6 mph – that’s near perfect. Energy is a punchy 1376, and the report says it’s excellent for experienced surfers. Monday the 31st and Tuesday the 1st back it up with 5-foot and 5-foot, both with light offshore winds and clean faces. The period drops a little to 15 seconds, but the quality stays high. This stretch is the absolute best on offer.
Remember, this is a reef. Those long-period swells with 15-plus seconds mean sets are well-spaced, paddling out is easier, but the waves themselves have heavy, steep lips. It’s an advanced spot, and on those cleaner days, crowds can be "sometimes" a factor, so you might have company. The 10-foot days earlier on are purely for the brave.
The second week is much more manageable. From the 25th, the swell drops to 4 to 5-foot, with periods staying decent but the energy tails off. Wind stays cross or cross-off, keeping things clean enough. The 27th has a little 5-foot pulse at 17 seconds, but the real magic is that end of August window.
Beginners should give this place a wide berth. Most of the time it’s over 5-foot, and with that reef bottom, you need your wits about you. For the experienced crew, the last few days of August and the start of September are the ones to chase.
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.
