The Lowdown
Yo, Rusty here. Let's get into it.
So, we’re looking at a bit of a slow start for Newcastle Beach, but there’s some real promise on the horizon if you’re patient. The gist is that the first week is pretty flat or just ordinary, but the second weekend and into the following week have a solid pulse of swell that could be the standout.
The water temp is sitting at 64°F on the first day, which is about 1°F cooler than average for this time of year, so nothing unusual, just your standard late winter chill.
The first real window of opportunity comes on Monday, August 3rd, in the morning. Newcastle Beach will see a 4 ft SE swell, period of 11 seconds, with a clean offshore breeze from the NNW at 9 mph. That’s a proper clean window with gentle offshore winds, making for tidy lines. The combined energy is moderate (311). It’s a nice, manageable size for beginners and intermediates alike, but it’s not massive. This is a good, solid option for a morning session.
After that, things go quiet. We’ve got a few days of small, weak surf – mostly under 3 ft, with short periods and poor conditions. There’s a gap from Tuesday the 4th right through to Thursday the 7th, where the surf is just too small or messy to bother with. Friday the 7th morning has a slight chance with a 4 ft S swell and a light WSW breeze, but it’s not a standout.
The real standout, the one you should circle on the calendar, comes on Sunday, August 16th. That’s when a new S swell kicks in at 6 ft, period 13 seconds, and builds further. The combined energy jumps to 1150 by the afternoon – that’s strong wave energy. But the real gem is Monday, August 17th, morning. We’re looking at a 6 ft S swell with a very long period of 15 seconds, glassy conditions with a light NW breeze. The energy is very strong (1388). This is excellent surf for experienced surfers – the size and period mean powerful, well-shaped waves, but it’s definitely not for beginners. The long period will likely make it break best at the point or reef sections of Newcastle Beach, giving you some nice, clean lines. The wind is glassy, so it’s going to be pristine. This is the best option in the entire 16-day window.
So, in short: the first week is mostly a dud, but hold out for that Monday, August 17th morning session for the best chance of a proper wave.

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.
