The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for Newcastle Beach.
Right now, things are a bit of a mixed bag. We’ve got a solid run of swell coming through, but the wind is going to be the main character for a while. The first real action worth talking about kicks off on Wednesday the 12th. It’s not going to blow your mind, but there’s a little pulse of S swell at 2ft and a period of 8 seconds pushing through. The wind is offshore from the WNW, so the surface will be clean. The wave energy is weak (101), so you’ll be hunting for the little runners. It’s a beginner-friendly spot, so it’s a good day to get the wobbles out.
Thursday the 13th sees a jump in size. The morning brings a 5ft S swell, short period at 8 seconds, with a cross-shore breeze. The combined energy is moderate (289), so there’s some push. But by the afternoon, it’s onshore from the SSE and the swell jumps to 6ft (558 energy). That’s getting a bit chunky for the beginners, and the onshore wind kills the quality. It’s marginal.
Friday the 14th is a day for the early bird. The morning has a clean 3ft SSE swell from a W light breeze. It’s weak (140) but clean. The afternoon turns onshore, so call it a morning session only.
The weekend is a write-off. From Saturday the 15th through to Thursday the 20th, the surf is consistently poor. The wind is cross-shore, cross-onshore, or onshore, and the swell is small and weak. It’s a long stretch of flatness and chop. Don’t bother.
Now, there is a glimmer of hope. The standout for the entire forecast is the morning of Friday the 21st. The wind goes glassy – dead calm – and we’ve got a 4ft E swell with an 8-second period. The energy is moderate (177), and conditions are described as surfable but ordinary. However, glassy conditions at Newcastle Beach are a major score. You’ll get clean, peaky little waves. It’s the best the forecast offers for a while.
The real highlight, though, is the morning of Saturday the 22nd. This is the one to circle. The wind is glassy with a calm, and the swell is a clean 4ft from the E with a period of 9 seconds. The combined energy bumps up to 210 (moderate). The forecast says "expect good surf conditions". This is the pick of the bunch. The water temp is about average for the time of year.
Then, Sunday the 23rd morning is also a ripper. A 6ft E swell (10 seconds) with a light offshore breeze (NNE). The energy is strong (674) and the forecast says "expect very good surf conditions". This is shaping up to be the best size and quality on offer, but it’s over a week away, so keep your fingers crossed. It’s a little too big for beginners, but for the experienced crew, it’s going to be pumping.
Monday the 24th morning is still decent at 4ft E swell with clean offshore winds, and Tuesday the 25th morning has a light offshore and a 3ft E swell, so the run of decent surf looks set to continue into the second week.
So, if you’re picking one session, make it the morning of Saturday the 22nd for the glassy conditions. For a bigger wave, Sunday the 23rd morning is the one to watch, but it’s a long way out.
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.
