The Lowdown
Alright, this is Rusty, and I’ve got to be straight with you—looking at the next 16 days around Castles, it’s pretty bleak. The whole run is a flat spell, no real swell to get excited about, and the conditions are mostly messy. We’re talking small, weak waves and a lot of cross-shore and onshore wind. The water’s sitting at a warm 78°, which is a solid 4° warmer than usual for this time of year—so you’ll be paddling in a bath, but there’s nothing to ride.
From Wednesday the 19th right through to the end of August, it’s a write-off. Swell heights barely crack 3 ft, and even then that’s a short-period, weak east windswell that’s just choppy and unrideable. The wind is a problem—cross-on or onshore most days, with a few mornings of cleaner conditions but literally no swell to work with. The combined energy numbers are all in the weak range, mostly under 100, so there’s just no power in the water.
There’s a long gap of nothing worth paddling out for until the very end of the window. The best you’re looking at is around Sunday the 30th of August. That morning, we get glassy conditions with a light northeast breeze, and the swell is a tiny 2 ft out of the southeast at 9 seconds—still weak, but at least it’s clean. The energy is 85, which is still weak, but you might get a few waist-high, crumbly ones if you’re desperate. That’s the only real standout, and it’s not much.
Then into early September, a little more energy rolls in—moderate levels around 150–160—but the swell direction stays southeast and the period is still short, so it’s not going to produce any proper waves. Winds are messy again. The morning of Wednesday the 2nd of September has cross-off breeze and a clean look, but again, tiny swell.
Bottom line: there’s no surf to speak of for the next two weeks. Castles is a sandbar setup that usually needs a decent swell to work, and it’s just not happening. If you’re a kite surfer, the stronger wind days might be more interesting, but for paddle surfing, save your energy.

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.
