The Lowdown
Alright folks, Rusty here. Honestly, this is a flat spell you could drive a truck through. The forecast is a real snoozer at Castles, a sandbar set-up that’s fairly exposed to swell but just isn't getting any love. The water's sitting at a balmy 77°, which is much warmer than normal for this time of year – feels more like a tropical bath than a surf zone.
Looking at the run, Tuesday the 8th kicks off with tiny knee-high 1ft waves from the ENE, but it’s a clean morning with a light cross-offshore breeze. We're talking brown water conditions, not surf. The swell energy is barely there, a weak 27, and it's poor. That's the story for days. Wednesday comes, the swell bumps up a bit to 2ft, but it's a messy 4-second wind-slop with a 12 mph cross-shore wind – not worth a paddle.
By Thursday the 10th, the wave heights hit 5ft from the SSW – the biggest of the run. The energy reading climbs to 212, which is moderate, but the period is a short 6 seconds. The wind is cross-off, so it’ll be clean, but it's just a lumpy, weak windswell. Not the kind of wave that makes you smile. Friday the 11th is a bust, back down to under 3ft.
There’s a long gap of nothing recommended here at all. The best we get is a fleeting moment on Monday the 14th morning. It’s tiny at 2ft from the SE, but the wind goes glassy. Zero wind. It’ll be a slick, pretty surface, but with that little energy (58) and a 9-second period, it's just a kiddie pool. Not really surf.
After that, the forecast is just a parade of weak, onshore, or cross-shore conditions with tiny waves. Saturday the 19th bumps up to 5ft from the NE with a moderate 206 energy, but the wind is a fresh 22 mph cross-shore, making it a choppy, lumpy mess. It looks more like a kite-surfing setup than a paddle-surfing day.
Truth is, there are zero standout days here. The consistency is low, the energy is low, and the quality is poor. It’s a blank run. Just leave the board in the shed and go for a swim in that warm water.

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.
