The Lowdown
Alright folks, Rusty here with a look at what Newcastle Beach has cookin' over the next couple weeks. On the whole, it's a bit of a mixed bag. The first few days are a total washout, then we get a quick bump of solid size that gets ruined by ugly wind, before a couple of clean windows show up. You'll have to be patient.
We start off with nothing doing. Tuesday the 15th sees tiny 1ft leftovers from the south, and even though Tuesday morning is glassy and clean with a light offshore, the energy is just not there – we're talking a weak 34 units of combined energy. Not worth waxing up for. Wednesday and Thursday are a different story, but not in a good way.
Wednesday the 16th gets slammed with a big 12ft south groundswell (period around 10 seconds) that's packing some serious punch – over 2000 units of combined energy. But it's all blown out by a strong 21 mph SSW cross-onshore. That's a kite-surfing setup, not a paddle-surfing one, and it's only for the experts if anyone dares. That mess carries into Thursday the 17th with the swell still a chunky 10ft from the south, but the wind stays ugly, keeping the quality poor.
Finally, we get a real highlight. Friday morning, September 18th, is the standout of the whole outlook. The swell drops to a much friendlier 5ft from the SSE, and the wind swings around to a light offshore from the NNW. Clean waves, gentle breeze, the water temp is sitting at 65°, which is pretty average for this time of year. The energy is moderate but clean (383 units). This is the one to aim for if you can get out of work. Newcastle Beach is a very consistent, exposed beach and reef setup, so when it's good, it's good. Hit it early.
Saturday morning the 19th is a second, smaller chance with clean 3ft south swell and a light offshore from the WNW. It's smaller, but still rideable and clean. Score it if you missed Friday.
Then the taps turn off. Sunday the 20th through to the middle of the second week is mostly tiny to small, onshore slop. There's a pulse of 8ft SSE swell on Tuesday the 22nd, but it's again cross-onshore and rough. Not worth it. The second week shows a few marginal moments, but the window for really good waves is shut.
Just keep an eye on that Friday morning (18th) – that's your best bet. The rest is either too big and windy or too small and messy.

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.
