The Lowdown
G’day, Rusty here. Let’s have a look at what’s coming down the pipe for our stretch of coast.
The next 16 days are a bit of a mixed bag, and honestly, there’s a quiet start before we see any real reason to get excited. The first worthwhile surf doesn’t show up until Wednesday morning, the 22nd of July. Before that, Tuesday the 21st is a write-off – small, choppy, and messy, with weak energy (62) and a short period wind swell. Not worth paddling out for.
So, the standout, and really the only highlight worth chasing, is Wednesday morning, the 22nd of July at Castles. We’ve got a solid 8ft swell rolling in from the SSW, with a period of 8 seconds. That’s a moderate amount of energy behind it (1152), meaning there’s some proper push. The wind is a cross-offshore from the WSW at 15 mph, keeping the surface clean. The water is a touch warmer than normal at 77°F – feels about right for summer. It’s a sandbar break that’s fairly consistent, though it can get crowded sometimes. This swell is a touch big for beginners, but it’s the best on offer by a long shot.
The rest of the week is pretty ordinary. Wednesday afternoon hangs on with smaller 5ft clean waves, but the quality drops. Thursday through Sunday the 26th of July is all small to tiny, poor surf with cross-onshore winds and choppy conditions, and energy levels are weak (under 100). Not worth a look.
We get a few flickers of life later. Wednesday morning, the 29th of July has a clean 3ft swell from the SSE with light cross-offshore winds, but the energy is only moderate (142). Conditions are clean, but the wave size is pretty marginal. Friday morning, the 31st of July is another one to keep an eye on – glassy conditions with a light 3ft SSE swell, but again, it’s very ordinary in terms of quality.
Heading into the first week of August, there’s a long gap with no real recommendations. Monday morning, the 3rd of August has glassy conditions and a 3ft SSE swell, but the energy is low (93) and it’s only surfable, not good. After that, the surf dries up again with tiny, clean waves and weak energy until the end of the forecast window.
So, if you’re keen, your best bet is that Wednesday morning, the 22nd of July. Get out there early for the cleanest conditions. The rest of the month is a waiting game, but it tends not to stay this flat for long – forecasts can change.

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.
