The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks at Castles.
Honestly, it's a tough start. We're looking at a long, dry spell right through the first few days of September, from Wednesday the 2nd right into the week after. There is simply no real surf to get excited about. The waves are tiny, mostly around 1.5ft to 2ft, and the energy is weak – you're looking at combined swell energy values mostly under 160. The wind's not doing us any favours either, with a lot of cross-shore chop messing things up. It's a real struggle.
Things finally start to show a pulse around Monday the 7th morning. We get a pulse of ENE groundswell at 3ft, and it's got a solid 10-second period behind it. The energy jumps up to a moderate 197, and for the first time we see a clean, light offshore wind out of the WNW. This is the best we've seen, but it's still only rated as "surfable but very ordinary". It's a small window of clean, lined-up waves on the sandbar, but it's brief. The afternoon gets chopped out again.
The next real glimmer is a long way off, on Wednesday the 16th morning. Another pulse of easterly swell, 3ft at 7 seconds, with clean conditions and a light offshore breeze. The energy is moderate at 116. It's still just "surfable", so don't expect fireworks.
If you're an absolute beginner, that Monday the 7th morning is your best shot – small, clean, and beginner-friendly. For everyone else, it's a waiting game. The end of the forecast window, on Thursday the 17th morning, shows a jump to 6ft from the east, with a moderate energy of 230, but the period is a short 6 seconds. That's going to be a bit of a bumpy, messy closeout, and it's over the 5ft mark, so not ideal for beginners either.
For a standout? Honestly, there isn't one. If I had to pick, it's the Monday the 7th morning session just for that brief moment of clean, offshore glass. But don't expect a classic. The wind and swell just don't line up for a proper session here.
Stay patient, mates. This is a quiet run for Castles.

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.
