The Lowdown
Alright, folks, let's get into it. We're looking at a pretty flat stretch ahead for Castles, that sandbar break we all know. Gotta be honest, the next week and a half is looking like a bust. The wave energy is just not there. We're talking tiny swell heights around 1.3ft to 3.6ft most days, with short, weak periods of 5 to 7 seconds. The combined energy readings are low, often scraping around the 20 to 125 mark – that's weak energy, no way around it.
From Tuesday, August 4th right through the weekend of August 9th, it's all poor surf conditions. The winds are all over the place, mostly cross or cross-onshore, chopping up what little bump there is. The water temp is about average for this time of year, nothing special there.
Now, there is a tiny glimmer. Look at Monday, August 10th and Wednesday morning, August 12th. We get a clean, glassy surface with light offshore winds (cross-off) from the west and north-northeast. The swell is still puny, only 2.3ft to 3.0ft, and the period is short at 6 to 7 seconds, so it'll be weak and crumbly. But for a longboard or a funboard, those windows might offer the only ridable, smooth little waves of the whole forecast. It won't be epic, but it'll be clean.
After that, it fades right back out into tiny, choppy, or onshore junk through to Wednesday, August 19th. Some of those later days have a slightly longer period around 8 to 9 seconds, but the swell height drops to practically nothing (0.7ft to 1.3ft), so it's just not enough to push you.
Honestly, this is a rough one for Castles. If you're desperate and own a big board, maybe check the windows on August 10th and 12th. Otherwise, save your wax.

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.
