The Lowdown
Alright, let’s get this out there. It’s been a bit of a flat, frustrating stretch for us here at Castles, and I’m not going to sugarcoat it. The finder is showing a whole lot of nothing for the foreseeable future. We’re looking at a solid run of poor conditions that stretches nearly two full weeks. You might see a ripple, but for the most part, it’s a waiting game.
To give you an idea of what we're dealing with, that first window offering anything at all isn't happening until Friday the 18th, and even then it’s marginal at best. The wait is the story here.
For that Friday morning (September 18th), we finally see a little life. The swell is a modest 4ft from the SSW with a short 6-second period. The wind, though, is the saving grace – a light NE offshore breeze and the conditions are clean. The water is a warm 77° which is almost 5° warmer than usual for this time of year, which is a pretty unique treat. It’s the only time the forecast even gives a one out of ten, which tells you all you need to know. But with such a short period, it’s not going to have any real punch. The combined energy is moderate at 107, but it's just too messy to get excited about.
After that, it’s right back to the same old story. The period from the 19th through the 24th just fades out, with nothing cracking the surface. The swell remains small and period stays short. The winds are mostly onshore or cross-onshore, and we get a few days of stronger SSW winds on the 23rd that will just chop the place up. The energy levels stay weak, mostly in the 30-90 range. This isn't a spot that needs a huge swell, but it needs *something* with a bit of period and a clean wind.
So, there you have it. One half-decent morning on the 18th and a lot of staring at an ocean that doesn’t want to play. The water is warm, that’s for sure, but that’s about the only highlight. It’s a bummer, but we’ve seen worse. This stretch of flatness is more normal for the area, so don't go thinking the surf is broken. Forecasts can change, and we just have to be ready when they do.

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.
