The Lowdown
G’day, Rusty here.
Look, it’s gonna be a tough couple of weeks for a surf at Newcastle Beach. We’ve got a solid run of small, messy, or just plain flat days to start, but there’s a proper pulse of swell working its way in for the end of the month and into September. You’ll need patience, but there are a couple of sessions worth circling on the calendar.
The first real sniff of anything rideable comes Thursday morning the 20th. The swell’s only 3ft from the ESE with a short 7-second period – weak energy (64). The water’s sitting at 63°, a bit colder than normal for this time of year, so don’t expect tropical warmth. The wind’s a light northerly, which is cross-off, and the wave comment says it’s surfable but ordinary. Honestly, it’s a 1-out-of-10 kind of morning. Not the place to be.
Then we hit a real dry spell. From Thursday afternoon the 20th all the way through to the 29th of August, it’s basically a write-off – poor conditions, tiny swell, messy wind. A few mornings have offshore breezes but the swell is just too small (0.7ft to 2ft) to make a wave worth paddling for. The combined energy readings are in the low teens to low hundreds, confirming the lack of push. You’d be better off waxing your board and staring at it.
Now, hang in there. Sunday the 30th of August morning shows a jump: 5ft from the ENE, 7-second period, light NNW offshore, and the combined energy hits 175 (moderate). It’s still only a 1-out-of-10 on the score, described as “surfable but very ordinary,” but it’s the first sign of life. The afternoon pushes up to 5ft, but the wind swings onshore and it gets marginal.
The real standout kicks off Monday the 31st of August morning. The swell is 5ft from the east at 8 seconds, combined energy is 385 (moderate), and we’ve got a light northerly cross-off breeze keeping it clean. That’s a 2-out-of-10 rating – first “expect good surf” call in the whole window. Newcastle Beach is an exposed beach and reef setup, so with the swell pushing from the east and the wind light offshore, the bank should offer up some fun, clean lines. It’s not huge, so beginners can have a crack, but it’s still over 5ft – keep your wits about you if you’re learning. Crowds are “often” around here, so expect company.
Tuesday the 1st of September is the absolute pick of the bunch. Morning session: 7ft from the east, 10-second period, so that’s a nice long-period groundswell, with a moderate WNW offshore wind. Combined energy is strong at 854. The wave comment says “expect very good surf conditions,” a 3-out-of-10. That’s the best we see. The afternoon glass off with 7ft easterly swell and glassy wind is equally clean. Now, 7ft to 7ft is getting into expert territory – beginners will be out of their depth. For the experienced crew, it’s going to be pumping. The long period (10 secs) will push the waves in with good shape and organised sets, though it might break a little straight on the beach. Chances are the banks will handle it.
Wednesday the 2nd of September cops a cross-shore wind and the quality drops. Thursday the 3rd is marginal. But then Friday the 4th morning brings another chance: 5ft from the south, 9-second period, light WNW offshore, combined energy 448 (moderate), and another “good surf” call (2-out-of-10). It’s a solid, clean option if the earlier windows don’t work.
So, bottom line: the first week and a half is a near-total blank. Save your energy for Monday 31st August morning and especially Tuesday 1st September – that’s the true standout. Friday the 4th September morning is a worthy backup.
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.
