The Lowdown
Alright, Rusty here, let’s talk about Newcastle Beach for the next couple of weeks.
Firstly, the water’s sittin’ around 64°F, which is a bit more than a degree cooler than average for this time of year – not a huge shock, but you’ll feel it if you’re not used to it.
The standout session of the whole run is Tuesday the 25th of August afternoon. We’re talkin’ glassy conditions with a light WSW breeze, and a 4ft swell from the ENE – combined wave energy at 231, so moderate and fun. The period’s only 7 seconds, so it’s a bit short and junky, but the surface will be clean as a whistle. Perfect for a late-afternoon paddle when you just want to feel that glide.
Another good one: Thursday the 27th of August morning. Glassy again, with a 5ft S swell, period 8 seconds, and energy at 302. That’s the punchiest, cleanest window in the first week. Newcastle’s very consistent, so you can bank on it.
After that, the quality fades. Friday the 28th morning is clean enough with a 4ft S swell and light offshore NW wind – okay, but nothing special. Then Saturday the 29th through Monday the 31st is mostly cross-shore winds, chop, and small swell. On the 31st, the period jumps to a long 18 seconds, but the swell’s only 2–2ft and the wind is cross-on. Those long-period waves won’t have the size to shape up properly.
Into the second week: Tuesday the 1st of September morning has a clean offshore NW wind, 2ft S swell with a 15-second period, energy at 280 – moderate but skinny. By Wednesday the 2nd, it’s even smaller. From there, the rest of the week is mostly weak, short-period, and often messy. The best you’ll get is Friday the 4th of September morning – a moderate offshore NW breeze with a 2ft S swell, period 7 seconds – surfable but not memorable.
So bottom line: you’ve got two real highlights – Tuesday 25th afternoon and Thursday 27th morning. The rest is mostly small, choppy, or just too weak to get excited about. It’s not a total dud – Newcastle’s consistent – but this forecast is more about pickin’ your moments than a full-on run of good waves.
Rusty.

Information about the Newcastle Beach Surf forecast
The above surf forecast table for Newcastle Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Newcastle Beach can be found by selecting the local surf guide option on the grey menu. Our Newcastle Beach 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 (Newcastle Beach) 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 Newcastle Beach 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.
