The Lowdown
G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks are a bit of a grind for waves around here. We’ve got a long stretch of small, messy, and often wind-affected surf before things finally fire up at the very end of the outlook. Don’t get too excited early on—this is a patience game.
The window starts with the best of a pretty average bunch on Wednesday morning. Newcastle Beach (Newcastle-Beach) will have a 4ft south swell with a 10-second period, and the WNW wind is blowing gentle and offshore, keeping things clean. The water’s sitting at 64°F, which is a touch colder than normal for this time of year—nothing crazy, but you’ll feel it. The combined energy is weak at 268, so it’s not punchy, but it’s the cleanest it’ll be for a while. If you’re a beginner, this is your window, because it’s not big and it’s not wicked. The swell direction is S, which is fine for the exposed setup here.
Thursday and Friday are ordinary. Thursday morning has a 4ft SSW swell, but the period drops to 7 seconds and the wind swings cross-shore, making it a bit of a mess. Friday morning glass off with a small 3ft south swell, but it’s lacking energy. These days are more about a paddle than a proper session.
The weekend turns ugly. Saturday and Sunday bring onshore SSE winds and rain, with swell bumping up to 5ft and 5ft, but the period stays short and the surface is chopped up. This is not the time to be out there unless you’re chasing something messy. The combined energy does jump on Saturday morning to 470, but it’s all short-period windswell, so it’s not worth the effort.
We’ve got a real gap from Sunday the 16th through to the 25th. There’s surf on the charts, but it’s small, weak, and mostly onshore or cross-onshore. Heights hover around 2ft to 5ft, but periods are short, and the wind is all over the place. There’s one brief moment on Wednesday the 23rd afternoon where a NW offshore breeze kicks in with a 3ft ENE swell at 10 seconds, and combined energy gets to 218. That’s a fun little clean wave if you’re desperate, but it’s not a standout. The rest of that stretch is just flat to gutless.
Now, here’s the payoff. Mark your calendar for Thursday the 27th, because that’s the day it all comes together. The swell pumps up to a solid 10ft from the south with a 10-second period, and the combined energy is massive at 2418. The wind is light and offshore from the west in the morning, making for excellent, clean conditions. This is a serious groundswell, and it’s going to be firing. But hear me out—this is only for experienced surfers. Anything over 8ft is expert territory, and this is pushing 10ft. The beach and reef setup here will have some juice, and with that size, it’s not for the faint-hearted. The morning session is the go; by the afternoon the wind swings onshore from the SE, the size backs off to 8ft, and it gets messier. This is the one true standout in the whole period, and it’s a week and a half away, so treat the long-range call with a bit of caution, but it’s looking proper.
So, in short: don’t waste your time this week. The surf is small and messy. If you’re keen for a wave, the Wednesday morning glass-off is your best bet for a clean, manageable surf. But the real event is Thursday the 27th—a big, clean south swell that’s going to have the banks working. That’s the one to plan for.
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.
