The Lowdown
Alright, Rusty here. Let me tell you how it's looking for our only spot on offer over the next couple of weeks.
So, we’ve got Scarecrows, a solid reef break, and it’s the only game in town. Don’t get too excited just yet though, because the first few days are looking pretty average with marginal conditions and a lot of cross-shore chop. We’ve got swell in the water, but the wind is just messy for most of it. There's a real standout window shaping up around Monday the 21st and Tuesday the 22nd, where things get clean and lined up.
Wednesday the 16th kicks off with a 5ft SSW swell, but a 25 km/h SE cross-off wind keeps it clean-ish. The wave energy is strong though, at 1115. Small but punchy. Thursday the 17th holds at 5ft from the SSW with a 15-second period, but that cross wind isn't doing us any favours. The energy is still strong at 1125. Friday the 18th drops to 4ft and the wind goes cross-on, which is no good at all. Saturday the 19th sees a nice jump in size to 6ft from the SW, but the cross winds and risk of thunderstorms spoil it. The energy jumps to 1794, but it’s unfriendly.
Now, Sunday the 20th is a mixed bag. Morning is still cross and messy, but the afternoon gives us a 6ft SW swell with a cross-off breeze, and the energy stays strong at 1722. That’s a glimpse of better things.
Here’s the gold: Monday the 21st. Morning session has a clean 6ft SSW swell (14 seconds) with a light SSE cross-off at just 10 km/h. The energy is 1307. Then the arvo... absolute glass. 6ft from the SSW, 5 km/h offshore from the ENE making it glassy. The energy is 1095. This is the pick of the whole outlook. Clean, lined-up reef waves for experienced surfers. The water temperature is about average for this time of year, so nothing weird there.
Tuesday the 22nd morning is also excellent with a smaller 3ft SSW groundswell and a 19-second period. That’s very long period, meaning it'll have a lot of push on the reef with long waits between sets. Clean with a light SE cross-off. Energy is 1053. Good for those who want the challenge. The arvo gets a bit messy with cross-shore chop.
The rest of the week slides back into mediocrity with cross-shore winds and smaller swell, though Wednesday the 23rd morning is clean with a 6ft SSW swell.
Then we get to the big stuff. Saturday the 26th of September morning looks solid: a 6ft SSW swell with a very long 20-second period. That's huge groundswell energy at 3680, meaning it will have serious power and length. The wind is a moderate cross-off from the SE, keeping it clean. Over 8ft by the arvo, so that’s expert territory. Sunday the 27th holds at 8ft in the morning, still strong, and the afternoon cleans up with a 8ft SSW swell and a cross-off breeze. That energy stays strong all weekend. Then it tapers down through the start of October.
But if you want the absolute best, it’s that Monday the 21st into Tuesday the 22nd. Glassy or clean cross-off winds, solid SSW groundswell, and a reef that loves that direction. The crowds? This spot can get busy, so expect company.
So if you can get out on Monday the 21st, do it. The rest of the window has waves, but you’ll be scratching your head with the wind for most of it.
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.
