The Lowdown
Alright, Rusty here, checkin' in from the beach. We've got a bit of a slow burner on our hands for the next couple of weeks. The first few days are a write-off, but there's a couple of windows if you're patient.
Right off the bat, Wednesday the 26th and Thursday the 27th are a complete mess. The wind is all wrong, onshore and choppy, with the swell all over the place. You'd be paddling out for a fight, not a fun wave. Put the board away for a couple of days.
So, everything starts to look up on Friday the 28th of August. That's our first real chance. Newcastle Beach is the go-to, and it’s a classic setup for this region. The water temp is sitting at 63.9°F, which is a touch under the norm for this time of year, but nothing to stress about. Friday morning is the absolute standout. The wind swings light offshore from the WNW, and we’ve got a solid 5.2ft of groundswell rolling in from the SSE with a nice 11-second period. That’s proper energy pushing through – you can feel the 664 (combined energy units) in the water. It's gonna be clean, lined up, and just a damn good session. The afternoon gets a bit messy as the wind picks up onshore, so get in early.
The weekend offers a couple of moments, but nothing like Friday. Saturday morning the 29th has onshore wind, so it's a pass. Sunday morning the 30th will be worth a look, with cleaner conditions and a dropping 3.0ft SSE swell, but it's a definite step down in size.
Looking further ahead, Monday the 31st of August has a proper little gem. The morning is glassy, flat calm, with a long-period 2.0ft SSE swell at 16 seconds. That’s pure groundswell, making for beautiful, clean lines on the bank. It’s small, but it'll be perfect for a longboard or a funboard. The energy is a moderate 345 (combined energy units). Then on Tuesday the 1st of September, we get a clean offshore wind from the NW again, with a consistent 2.6ft SSE swell. Good, clean, fun waves.
After that, the second week dries up fast. From Wednesday the 2nd of September onwards, the swell drops right off. We're looking at tiny waves, under 2.0ft, with very weak energy readings (mostly under 100 combined energy units). There're a few morning windows with offshore wind, like Thursday the 3rd and Friday the 4th, but the swell is just too small to get excited about. It's a long, flat run until we get a couple of glassy, tiny bumps on the 8th and 9th of September. Those are for the most dedicated souls with a foamie.
So, to sum it up: the only true standout is Friday morning, the 28th of August at Newcastle Beach. Get that session. The rest is a waiting game or a longboard cruise.

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.
