The Lowdown
Right, gather 'round, it's Rusty here. Let's have a look at what's cookin' for the next couple of weeks.
First up, to be straight with you, it's a tough start. We're looking at a long, quiet stretch with barely a ripple. The first real chance of a wave doesn't come until Sunday morning, August 9th, at Castles. Even then, it's a modest 4ft SSW swell, but with a clean, cross-offshore wind making it look tidy. The energy is moderate (224), and it's a sandbar setup that's fairly consistent. It's not pumping, but it's the first sign of life after a flat spell. For a beginner-friendly spot, it's a decent way to ease back into it.
After that, it's back to the doldrums for a solid week. The water temp is about average for this time of year, so you won't need a steamer, but you'll be waiting.
Now, for the real glimmer in this forecast. Look ahead to Tuesday morning, August 18th. The wind goes glassy, the air is still, and the water turns into a mirror. We've got a 2ft SE groundswell pushing in with a period of 10 seconds, and moderate energy (113) to back it up. It's a long period, so it'll be more drawn out, but at a sandbar, it might still offer some fun lines. Conditions will be the real winner here.
Then, the true standout. Saturday morning, August 22nd. Another glassy morning, with a 3ft SE swell, this time with a 12-second period and a solid 212 energy reading. The wind is a whisper from the SE at 5 km/h, and the report says "glass" – the cleanest of clean. The area is "sometimes" crowded, so expect some company, but for a spot that's been quiet, this is the session to aim for. It's not a big wave, but it'll be a beauty.
Finally, on Sunday, August 23rd, the swell jumps up to 7ft from the S, with a period of 7 seconds. That's a short period, bumpy energy, and it's likely to be a messy, powerful close-out. The energy is strong (703), but it's a marginal forecast. For a sandbar with that size and short period, it'll be a washing machine. This one is for the experts only, and even then, it's going to be a handful.
So, to sum it up: the first week is a write-off. The second week has two real standouts: the glassy Tuesday morning on the 18th, and the pristine Saturday morning on the 22nd. Mark your calendars.
Rusty.

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.
