The Lowdown
G’day, Rusty here. Let’s have a look at what Newcastle Beach has got cookin’ for us over the next couple of weeks. Right now, the water’s sitting at 64°, which is a bit colder than normal for this time of year – about 2° off the average, so you’ll want a decent wetsuit if you’re heading out.
Honestly, the next week or so is pretty flat and messy. We’ve got a long gap with nothing worth paddling out for until late in the forecast. The first real chance of a wave doesn’t show up until Sunday the 30th of August, and even then, it’s a big one.
For most of this week and next, we’re looking at tiny, weak surf with combined energy readings barely tickling the 100 mark – mostly 30 to 100, just weak energy. Winds are all over the shop, and conditions are ordinary at best.
The one true standout, and the only time I’d get excited, is Sunday morning the 30th of August. Newcastle Beach is an exposed beach and reef setup, and we’ve got a serious, powerful SSE groundswell rolling in at 12 ft with a very long 18 second period. The combined energy is a massive 10,361 – that’s very strong. Now, that’s a lot of punch. For beginners, this is way too big (over 8 ft) – we’re talking expert territory only, and even then, a long period swell like this can break a bit straight on a beach break, so watch for that. It’s a big, clean, powerful setup but it’s not for the faint-hearted. Winds are gentle cross-shore from the SSW, keeping the surface tidy.
After that, Monday morning the 31st cleans up nicely – glassy conditions with an ESE breeze and a solid 6 ft SSE groundswell (moderate energy at 956). That’s a great window for experienced surfers wanting clean, lined-up waves. Tuesday morning the 1st of September also offers some clean glassy conditions with a 4 ft SSE swell – worth a look if the Monday is too big for you.
So, to be blunt: there’s a long dry spell until the last day of August. When it fires, it fires big. If you’re an expert, mark that Sunday the 30th morning. If you want something a bit more mellow, the Monday morning glass-off is your best bet. Crowds are often on this beach, so expect company.
This is Rusty, signing off.

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.
