The Lowdown
Alright folks, Rusty here. Let's talk about what we've got cookin' at Castles.
The next couple of days are a write-off, to be honest. The swell is there, sure, but it's messy. We've got a long-period SW groundswell pushing in at 8ft on Tuesday morning, but the wind is a cross-on from the SSW. It's choppy, and the water temp is sitting at 60°, which is about average for this time of year, nothing to write home about. The wave energy is strong at (2872), but it's just not clean. Tuesday afternoon is a little better with some cross-shore wind, but it's still got a slight chop.
The real window opens up on Wednesday the 15th. This is the standout. The morning is looking clean with a gentle offshore breeze from the ENE. The swell drops a bit to 5ft from the SW, but that wave energy is still healthy (1108), and with a long 15-second period, these are proper groundswell lines. This isn't a beachbreak, it's a reef, so that long period will actually set up beautifully, offering some real shape and power. The conditions stay glassy through the afternoon, too. This is the time to be in the water.
Thursday the 16th still has some decent 5ft SW swell with a 15 to 17-second period, and the wind is a cleaner cross-off, but the energy is already starting to drop off. It's surfable, but not the standout Wednesday is.
From Friday the 17th onward, the swell fades fast. We get a few days of marginal 4ft to 3ft surf, but it’s weak. Then there's a long, flat spell from around the 19th through the 22nd. The swell energy drops into the 200s and 300s, and the wind turns messy. Tuesday the 21st morning looks interesting for a moment – glassy conditions and 4ft – but the wind swings onshore by the afternoon and kills it.
We get another pulse around Thursday the 23rd, a SW swell pushing back up to 6ft with pretty strong energy (1363). But the wind is a cross-shore with some chop, and it's a week and a half out, so keep an eye on it, but don't lock it in.
The end of the run on Wednesday the 29th afternoon throws a curveball. A sudden spike to 8ft from the WSW with a short 9-second period and light offshore wind. The energy is solid (1360). That's a lot of juice and size for an afternoon session, but with such a short period, it’ll be a bit walled-up and fast, more for the crew who know their way around a reef.
So, for the best bet: don't miss Wednesday the 15th. That's the one where it all comes together. After that, you've got long stretches of flat, small stuff, so make that day count.

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.
