The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
We’ve got a pretty flat run ahead. The entire 16-day window is a tough one for Castles, with nothing but poor surf conditions across the board. The first real opportunity to get wet doesn’t even show up until the 13th of September, and even then it’s a bit of a stretch. There’s a significant gap of almost two weeks of no-go surf from the start of the period.
The only standout, and I’m using that term loosely, is the Sunday morning of the 13th of September. We’ll see a brief window of glassy conditions with a 3ft swell from the SW. The combined swell energy is a weak 46. It’s a short period swell of just 4 seconds, so it’s not going to have much push or shape, but it’s the only time the wind truly cooperates. For a seasoned local, it might be worth a paddle for a few small, clean ones. But honestly, for beginners, even that 4ft later in the day is a bit much, and the 3ft is just about the limit for a total beginner on a good day.
Just a heads up, the water temp is about average for the time of year, nothing unusual there.
The whole rest of the forecast is a write-off. The wind is mostly cross or cross-on, and the swell is tiny, with periods often under 8 seconds. The 2nd of September sees a bump in energy to 123 (moderate) with a 2ft, 11-second SE swell, but the cross-on wind chops it up. The 11th of September has some fresh offshore wind, but the swell is only 1ft to 2ft, just not enough to do anything with. It’s a frustrating run for a wave-starved surfer.
Hang in there. The forecasts can change. Rusty.

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