The Lowdown
Alright, surfers, Rusty here. Let's be straight with you: the next couple of weeks are a bit of a slow grind for our stretch of coast. We're looking at a lot of small, weak, or messy conditions, so we've got to be patient and pick our moments.
For the first few days, from Friday the 4th to Tuesday the 10th, it's pretty much flat to tiny. There might be the odd knee-high ripple, but nothing with any push or shape. We're talking weak energy readings in the 30s and 40s, and a lot of it is chopped up by cross-shore winds. You're better off waxing your board for later, or just enjoying the beach. Thursday the 10th sees a bit more push with the swell jumping to 5ft, but it's still poor quality, with onshore winds making a mess of it.
We finally see a flash of something on the morning of Sunday the 13th. There's a jump in the energy to around 316, which is moderate, and a clean 6ft swell from the NE with a 7-second period. This is the standout morning of this stretch. This is a sandbar set-up, so it should offer some corners. It's fairly exposed, and if we get that morning light and clean conditions, Castles could be the spot to be. The NE direction is right in its wheelhouse. The brutal part is, the onshore wind swings around in the afternoon and pretty much kills it, and it looks like it's back to the small stuff for the following days. So, Sunday 13th is the one to circle.
After that, the rest of the second week is again mostly small. We get another pulse of 5ft on Saturday the 19th, but the energy is a bit weaker and the periods are short. At over 5ft, it might be a bit much for beginners if it gets any bigger, but it's worth a paddle for the more experienced crew.
So, the call is this: it's a lean couple of weeks. There are long gaps of nothing, so don't get your hopes up. Your best bet is the clean Sunday morning on the 13th. If you miss that, you might be waiting a while. The early calls are the most reliable, so keep an eye on the forecast closer to the 19th, but for now, that's the outlook.
Rusty out.

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.
