The Lowdown
Alright folks, Rusty here. Let’s have a look at what Newcastle Beach has in store for us over the next couple of weeks. It’s a bit of a slow start, but there’s a couple of proper windows to get excited about if you’re patient.
We’re looking at a classic beach and reef setup, exposed to the southerly swells. The water temp is sitting right around average for this time of year at 66°F, so no surprises there.
The first proper surfable window doesn’t really open up until Monday the 7th. The weekend is pretty flat and ordinary, with a small 2ft S swell on Saturday the 5th blown out by a NNW wind at 15 mph. Sunday the 6th is even worse, with a tiny 2ft S swell and messy cross-onshore wind. It’s a grim start.
Monday the 7th morning brings a bit of hope. We’ve got a 5ft S swell, period around 8 seconds, with a light cross-shore wind. The combined energy is moderate at 288, but it’s a marginal call. The wind turns onshore by the afternoon, so early morning is your only look that day.
Tuesday the 8th sees the swell build to 7ft from the SSE, but with a strong cross-onshore wind, it’s a no-go. Wednesday the 9th and Thursday the 10th are also messy with onshore wind, even though the swell sticks around 5ft to 8ft. This is a period of plenty of water but lousy conditions—if you’re into kiting, the beach setup might actually be more interesting than paddling.
Now, here’s the standout. Friday the 11th morning is the one to circle on the calendar. We’ve got a solid 6ft S swell, period stretching out to 11 seconds, and the wind is glassy—dead calm, SW at just 3 mph. The combined energy is pumping at 946. That’s a proper groundswell, and at Newcastle Beach, that longer period can make for some excellent, clean lines. The crowd is often there, and with conditions this good, expect a few locals out. It’s not for beginners at that size—6ft is pushing it for the less experienced—but for the crew who know what they’re doing, it’s going to be magic.
Saturday the 12th morning is still decent with a 5ft SSE swell and glassy conditions again, but the energy drops to 458. Worth a paddle if you missed Friday.
The following week is a mixed bag. Sunday the 13th morning offers a clean 3ft S swell with an offshore NW breeze, and Monday the 14th morning keeps that clean feel with a similar 3ft SSE swell and offshore wind. These are small but fun, easy-going sessions.
We get a bit of a windswell bump mid-week on Tuesday the 15th and Wednesday the 16th, but it’s blown out again with strong winds. Skip it.
The next real highlight comes late in the window. Thursday the 17th morning looks clean with a 4ft S swell, 11-second period, and a light cross-offshore breeze. Then Friday the 18th morning is another cracker: a 5ft S swell, 11 seconds, combined energy a strong 1014, and a light offshore cross-off breeze. That’s a proper session for experienced surfers—clean, powerful, and well-shaped. It’s 18 days out, so keep an eye on it, but it’s got real promise.
After that, the swell tails off into smaller, cleaner but weaker waves through the weekend of the 19th and 20th, with 2ft to 3ft SSE swells and offshore winds. Fine for a longboard or a cruise.
So, bottom line: the standout is Friday the 11th morning at Newcastle Beach. Glassy, solid S groundswell, and all the energy you need. The second week’s Friday the 18th morning is also a beauty to watch for. The rest is mostly average or blown out, but those two windows are worth the wait.
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.
