The Lowdown
Alright, Rusty here. Let’s talk about what’s coming down the line for the region.
We’ve got a solid run of south swell on the way, but it’s not all blue skies. The water’s sitting at about 85° – that’s pretty much normal for this time of year, so nothing freaky going on with the temp.
The first real chance to paddle out doesn’t hit until Friday, 14 August. That morning, Scarecrows is cleaning up nicely. You’re looking at a 8ft south swell, period around 16 seconds – that’s serious groundswell energy, with a moderate combined energy of 2692. The wind is a light cross-offshore breeze, so the faces will be clean. This is for the experienced crew only; 8ft on a reef at that size, you need to know what you’re doing. The water is glassy, and that’s a major positive.
Saturday afternoon, 15 August, is another highlight. The swell drops to 5ft from the south, still a decent 13-second period, and the combined energy is 1406. Light offshore wind again, clean conditions. This is a great window for anyone who found Friday a bit too meaty. The reef will be working, but the size is more manageable.
Then, hold onto your board. The standout window is Tuesday morning, 18 August. Scarecrows gets a 7ft south-southwest swell, period 16 seconds, combined energy of 2313. The wind is light and from the southeast – clean, cross-offshore. This is the best on offer. The swell direction is right in the sweet spot for the reef. After that, Wednesday 19 August is pumping solid 8ft south-southwest swell, but the wind is more cross, so it’ll be a bit bumpy. That’s expert territory only.
The second week gets a bit more mixed. There’s another promising window on Saturday morning, 22 August, with a 8ft south-southwest swell and clean offshore winds, but it’s further out, so keep an eye on it. Later in the week, Thursday morning, 27 August, offers a smaller 5ft south-southwest swell with light winds, giving clean conditions again.
Overall, if you’re after the best, get on Tuesday 18 August. Friday 14 August is a close second for the bigger, experienced crew. The rest of the run has waves, but the wind and tide are a bit more fickle.
Stay safe, and don’t be a hero if it’s too big.

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.
