The Lowdown
Alright, mate, Rusty here. Let’s have a look at what we’ve got cookin’ at Newcastle Beach over the next couple weeks.
Right off the bat, honest truth? It’s a bit of a mixed bag. Not a whole lot of straight-up glory days, but there’s a flicker or two if you’re patient. The first few days are pretty ordinary, with small, weak swells and iffy winds. It’s not until Saturday the 12th that we see a real window of opportunity, but even then, it’s short-lived. The standout for the whole period is going to be that Saturday morning.
So, let’s get into it. The first real sniff of something worthwhile is Saturday morning, September 12th. Newcastle Beach is a beach and reef setup, exposed to a SE swell. The water temp is sitting around 65°F, which is pretty much bang on average for this time of year, so no surprises there. That Saturday morning, we’re looking at a tiny 2ft swell from the SSE, but here’s the kicker – the wind is glassy, dead calm from the south at just 3 mph. That means the ocean will be like a mirror. The swell period is a very long 19 seconds, so it’s pure groundswell energy. This will bring long, clean lines, but with that tiny height, I’d call it a small-wave special. Perfect for a beginner or anyone wanting to get a longboard out and glide without a ripple on the water. Combined energy is moderate at (468), and with the glassy conditions, it’s the cleanest the break will look all fortnight.
Now, don’t get too excited for later that same day – Saturday afternoon the wind swings onshore and chops it all up. Then we’ve got a bit of a lull. The next interesting one is a couple weeks out. On Friday, September 25th, we’ve got a clearer outlook for the morning. Swell bumps up to 4ft from the SSE with a long 12-second period. The wind is a light offshore from the NNE at 6 mph. That’s a cross-offshore, which is a major plus for keeping the faces clean. The combined energy is moderate at (359), and the forecast points to good conditions. It’s a promising option for a session, but being that far out, take it with a pinch of salt – forecasts can shuffle around.
Before that, on Wednesday, September 16th, we get a serious pulse of swell – 10ft from the south on Wednesday morning. That’s big, solid power with combined energy hitting (1680), which is very strong. But don’t get your hopes up. The wind is a fresh cross-onshore blow at 22 mph, turning it into a lumpy, choppy mess. That’s more of a kite-surfing kind of energy than a clean paddle situation. Not recommended for the average surfer, and definitely not for beginners.
For the rest of the period, it’s mostly small, weak, or onshore. There’s a gap of several days between the glassy Saturday and the next real highlight on the 25th where you’re just looking at ankle-to-knee high slop. No real standouts other than that.
So, if you’re keen, pencil in Saturday morning, September 12th for the cleanest, glassiest little waves, or keep an eye on Friday morning, September 25th for a slightly bigger but less certain option.
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.
