The Lowdown
Alright, let me put it in feet and miles per hour for you. Rusty here. Straight up, the next two weeks are a bit of a drought. Mostly tiny, bumpy surf with only a few windows that look half-decent.
We've got a bit of a gap at the start. The first few days of September are a total loss—weak and choppy. Your first real look-in comes Monday morning, September 7th, at Castles. This is a sandbar that can hold a few people, so don't be surprised if you're not alone. The swell is a modest 3ft from the ENE, with a clean cross-offshore breeze. The energy is mild (109), so you'll be working for it. Water temp is about what you'd expect for this time of year.
Tuesday the 8th is much the same—around 2ft from the ENE, clean and light, but the energy is still only moderate (100). It's a "maybe get a few grovelers" kind of session.
If you're holding out for something with a little more punch, look to Wednesday the 16th of September. The energy jumps to a solid 154, with a 3ft swell from the E at a longer 10 seconds. That longer period will give the waves some shape, and with light winds it should be pretty clean. It's your best bet for a decent paddle.
There's a bigger bump on Sunday the 6th with 6ft from the ENE, but a fresh cross-wind of 19 mph turns it into a lumpy mess. Honestly, that's kite-surfing weather, not surfing weather.
So, bottom line: nothing huge, but Wednesday the 16th is the standout. The smaller mornings on the 7th and 8th are your other options. It ain't prime, but it won't stay flat forever.
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.
