The Lowdown
Alright, this is Rusty comin' at ya from the beach. Let's have a look at what's on the menu for the next couple of weeks.
Right off the bat, I gotta be straight with you – the first week or so is a bit of a tough one. We're looking at a real dry spell, with tiny, weak, messy waves. You'll be waitin' until the 31st of August just to see a ripple that's barely surfable, and even then, it's nothin' to write home about. The real action doesn't start to build until we get into September.
The best bet on the whole board, the one that's got me a little excited, is the morning of Thursday, September 3rd at Castles. This is a sandbar break, so it's a bit of a gamble, but the conditions are aligning. We've got a clean 4ft swell rollin' in out of the SE, with a nice 13-second period behind it. That's some proper groundswell with real push. The wind is a light WSW cross-off, which is gonna leave the surface glassy. The combined energy is a solid 374, which is moderate, but it's the cleanest, most promising window we've got. The water is much warmer than usual for this time of year, sittin' around 78°, so you can leave the steamer at home.
The morning of Friday, September 4th is another one to circle on the calendar. The swell is pushin' up to 6ft from the ESE, still with that 13-second period and a cross-off wind from the W. The energy jumps way up to 1001, which is strong. Now, 6ft is getting into the territory where it might be a bit much for beginners, but for the rest of us, it's a solid, clean wave. Keep an eye on that tide, though, as the report flags it as a bit questionable.
The whole first week of September is a definite step up from the August doldrums. The swell stays consistent, and the winds are mostly offshore. The 6th of September has a nice 5ft swell with a clean offshore wind in the morning, though the period drops to 8 seconds, making it a bit more of a windswell feel.
So, to sum it up for a local lad: Wait it out. The beginning is a write-off. The standouts are the mornings of September 3rd and 4th at Castles. Get on it before the wind shifts in the afternoon. It's a promising forecast, but it's a game of patience.
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.
