The Lowdown
G'day, Rusty here. Look, I've had a good look at Newcastle Beach and the next couple of weeks are a bit of a mixed bag. The water's sitting at 63°, which is a bit colder than we'd normally expect for this time of year, so you might want an extra springy.
For the first few days, from Friday the 21st right through the weekend, it's pretty flat and unappealing. We're looking at tiny waves, mostly under 2ft, with weak energy (30) and short period swell. Not worth paddling out for.
The first real hint of something worth checking comes on Sunday the 23rd morning. We've got a glassy 3ft south swell coming in with a solid 11-second period. The combined energy jumps to 162, which is moderate, and with those calm, glassy conditions, it's going to be clean. It's a small, long-period groundswell, so it might be a bit too straight for the beach break, but it's your best bet for a quiet, easy paddle.
Then we get a bit of a lull through the week, with small, onshore days. The energy picks up a bit on Monday the 31st. The afternoon session looks the goods: clean with a moderate offshore breeze, 4ft of east swell, and combined energy of 226. It's not huge, but it's clean and surfable.
The real standout, though, is looking like Thursday the 3rd of September. That morning we've got a clean 3ft swell from the ENE with a 10-second period, combined energy of 352 – that's a solid, moderate push. The wind is light and offshore, making it clean. The swell direction is also a good match for the break. Just keep an eye on the crowds, as it can get busy here.
After that, we're back into small, clean conditions for the weekend of the 5th, but nothing to get too excited about. Overall, if you've got a longboard, Sunday the 23rd morning is your glassy, quiet session, but for the best all-round quality, pencil in Thursday the 3rd of September.
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.
