Table - best surf conditions forecast for Castles over the next 16 days.
Alright folks, Rusty here. Let’s have a look at the forecast for Castles. It’s a reef break, exposed to a WSW swell, and it’s consistent. The water temp is sitting at 60°, which is about average for this time of year – nothing to complain about there.
The next 16 days start off pretty rough, I’m not gonna lie. We’ve got a gap of no real surf to recommend right through the first few days. Saturday the 11th and Sunday the 12th are a write-off. The wind is howling onshore from the WSW and SW, pushing up a messy 7ft to 7ft swell with short, weak periods. The combined energy is moderate, but it’s all raw and lumpy – not worth paddling out for.
Monday the 13th actually sees a big jump in size and energy, with a 8ft to 10ft, 16-second groundswell packing a lot of punch (combined energy reading 3039 and 8310). But the wind is still onshore or cross-onshore and strong, making it a total mess. This is one for the experts only, if anyone, and honestly, the setup looks more interesting for kite surfing than paddle surfing right now.
Tuesday the 14th is still marginal. The swell is still a solid 7ft to 7ft with that long 16-second period, but the wind is light and variable, keeping it choppy and onshore. It’s just not clean.
Now, here’s the standout. Wednesday the 15th of July is your best window. The swell drops to a clean 5ft to 6ft from the SW, with a nice 14-second period. The real magic is the wind: it goes light offshore from the NE and ENE. That’s clean, glassy conditions for a reef break. The combined energy is still moderate (1187 and 998), but for a point break or reef, that long-period groundswell will line up beautifully. The break is exposed and consistent, and with offshore winds, this is the best on offer. Crowds are a possibility, so get in early.
Thursday the 16th through Friday the 17th, the swell drops to 4ft to 4ft. The wind is clean from the NNE, but it’s a cross-offshore breeze. The surf is rideable but marginal, with moderate energy. It’s not a standout, but it’s a lot better than the weekend.
Saturday the 18th is a mess again. The swell gets tiny (2ft to 3ft) and the wind cranks up to 25 mph from the north. Not worth it.
Sunday the 19th brings a fresh pulse of 6ft to 7ft, 17-18 second groundswell, but it’s hammered by strong onshore winds. Another pass.
From Monday the 20th through to the end of the period, the surf is a mixed bag of small to moderate swell (3ft to 7ft) but the wind is almost always onshore or cross-onshore and strong, keeping it lumpy and choppy. There are a few mornings with cleaner cross-offshore breezes, but nothing that tops Wednesday the 15th. That Wednesday is your day.
Signing off, 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.
