The Lowdown
Alright, let's break down what's brewing for Castles. Gotta be honest, the surf forecast is looking pretty bleak for the next couple of weeks. We're in for a long stretch of small, messy conditions.
The only real window that has any potential is that Thursday the 10th. It’s not a world-beater, but it's the best of a bad bunch. In the morning, we'll see a 5ft swell coming from the SSW with a weak 6-second period. The wave energy is moderate at 173. The wind will be offshore from the WSW, so the surface should be clean. That's a rare bright spot. The afternoon sees the swell drop a little to 5ft from the same direction, still clean with a cross-off breeze from the W, and the energy bumps up to 284. It’s surfable, but with that short period it’ll be a bit weak and fat. It's not too big, so most folks can handle it, but the experts will be left wanting.
Beyond that one day, it's a total desert. We've got a big hole from the 7th of September all the way up to the morning of the 10th. After that Thursday afternoon, it goes quiet again. The 12th and 13th might have a few 2-3ft sliders, but the wind is onshore or cross-onshore, making everything choppy and uninviting. The 16th of September shows a hint of a clean offshore breeze from the WNW with a tiny 1ft swell from the SE with a 9-second period, but the energy is a measly 33. That’s barely a ripple. Then it fades again, with the 20th showing a 4ft NE swell in the afternoon but with a cross-shore wind and lumpy chop. Not a paddler's friend.
Look, if you really need a fix, pencil in that Thursday the 10th, but don’t get your hopes up for anything else. On the bright side, the water is way warmer than usual for this time of year, a balmy 77°F.

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.
