The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Newcastle Beach.
Right now, we’re in a quiet spell. The beginning of the period is pretty average, nothing to get excited about. Our first proper look comes on Wednesday the 12th. It’s not a classic, but we’ll take what we can get. The swell is a modest 4ft from the S with a period of 10 seconds, giving a moderate combined energy of 268. A WNW breeze keeps things clean and offshore, which is exactly what you want. The water temp is about average for the time of year. It’s a solid beginner-friendly option to get wet.
Thursday the 13th turns ugly. The wind goes all wrong, swinging cross and onshore, and the swell period drops below 8 seconds. It’s a write-off.
There’s a glimmer on Friday the 14th morning. A tiny 3ft S swell with a very short period, but the wind is light and cross-offshore, so the surface is clean. It’s surfable but ordinary, a real grovel session for the longboard or a foiler.
The weekend is a total mess. From Saturday the 15th through to Tuesday the 19th, we’re looking at onshore winds and choppy conditions. The swell builds a bit, hitting 6ft on Monday the 17th, but with a short period and wind on it, it’s just a lumpy, ugly beast. The combined energy gets up to 416 (moderate), but it’s not worth paddling out for.
Now, here’s where things get interesting. Mid-week, we have a proper standout. Wednesday the 19th morning is the one to circle on the calendar. The wind goes glassy—dead calm—with a light S breeze. Swell is 6ft from the E, with a period of 8 seconds, and the combined energy jumps to a strong 623. The guidance says it’s a SE optimum, and while this is E, the glassy conditions and solid size will make it clean and fun. For a beach break, that period means it’ll have some shape, and the paddling out won’t be a nightmare between sets. It’s the best on offer, no question.
After that, we get another nice window. Thursday the 20th morning is glassy again with a 5ft E swell and a combined energy of 317 (moderate). Another clean session, but the swell is a touch smaller.
The following weekend, the 22nd and 23rd, looks promising with clean conditions and a longer-period E swell (10-11 seconds). The swell is 4ft to 4ft, but the long period and light offshore winds will make for some nice, lined-up waves.
Then we hit a gap. Monday the 24th and Tuesday the 25th are marginal at best, with strong offshore winds that might make it tricky. Tuesday the 25th afternoon has a weak, short-period S swell that’s onshore—skip it.
The very end of the window, Wednesday the 26th and Thursday the 27th, offers a big punch. Wednesday morning has a glassy, clean 6ft S swell, but Wednesday afternoon sees a massive 12ft S swell with a period of 10 seconds and a combined energy of 2357 (very strong wave energy). That’s huge, and with cross-onshore wind, it’ll be a choppy, expert-only mess at Newcastle Beach. But Thursday the 27th morning looks like the real payoff: a clean 8ft S swell with a 9-second period and a combined energy of 999 (very strong). The wind is light and cross-offshore from the NNW. This is the second standout of the outlook—big, clean, and powerful. It’s a long way out, so things can change, but the potential is there for a proper session.
So, to sum it up: the first week is a write-off until Wednesday the 19th. That’s your first real standout with glassy conditions. The second standout is the very end, Thursday the 27th, with a solid swell and clean wind. Don’t waste your time on the in-between.
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.
