The Lowdown
Alright, Rusty here. Let’s have a look at what Hideaways has in store for us.
This is a reef break that really knows how to put on a show, but you’ve got to be patient. The first few days are a bit of a mixed bag, with some decent energy building but the bite of strong winds and that tropical rain squall potential making it feel a bit wild. The water's sitting at a normal 81°, nothing unusual there.
We kick off on Friday the 14th with a clean 6ft swell from the ENE, but it’s a bit weak with only 426 combined energy. It’s surfable, but nothing to race for. Saturday the 15th sees the swell jump to 7ft from the east, and the energy ramps up to 905 – moderate and clean in the morning, but getting choppier through the afternoon as the wind swings more cross-shore. Sunday the 16th is the first real standout of the window. We’re looking at a solid 15ft swell from the east, with a massive 4361 energy rating. That’s a lot of water moving. The wind is cross-offshore, keeping things clean, but at that size, this is for experts only. Beginners, stay well clear.
Things settle quickly after that. Monday the 17th drops back to 6ft, and from Tuesday the 18th through to Friday the 22nd, it’s a stretch of weak, marginal surf. Most days are under 5ft with combined energy often below 200-300. It’s not great. There’s a tiny bright spot on Thursday the 20th afternoon, where a 4ft swell and a "good surf conditions" tag pop up, but it’s fleeting and the wind is barely offshore.
Then we get a solid gap of nothing much until the end of the month. That’s where the real gold is. Starting Wednesday the 26th morning, we get a clean 6ft from the ENE with 697 energy. It’s good. But the true highlight is from the 27th to the 28th. The swell drops back to 4ft to 4ft, but the period jumps to a very long 16-18 seconds – that’s a proper groundswell. The combined energy climbs up over 1300, and the wind is light to gentle offshore. That’s the kind of classic reef setup where the lines just roll in with power and shape. For experienced surfers, Thursday the 27th and Friday the 28th mornings are the best on offer.
By Saturday the 29th, the energy starts to fade back down into the 800s, still with a long 14-15 second period, but the size drops to 3ft. Good for a fun last session, but not a standout.
Overall, if you can wait out the first two weeks of mediocrity and strong wind, that final week of August has some absolute gems waiting. But remember, at Hideaways you often get crowds, so keep your eyes open.
Rusty.

Information about the Hideaways Surf forecast
The above surf forecast table for Hideaways provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hideaways can be found by selecting the local surf guide option on the grey menu. Our Hideaways 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 (Hideaways) 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 Hideaways 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.
