The Lowdown
G'day, I'm Rusty.
Let's be honest – Newcastle Beach is in a bit of a flat spell to start. The first week is mostly a bust with small, weak swell and onshore winds creating poor conditions. You'll see waves from 1 to 2 feet, coming from the SSE and ESE, with combined energy staying low, under 300. Nothing to write home about.
The water is sitting at 63°F, which is a bit colder than usual for this time of year. Bring a thick suit.
The only real highlight is Wednesday morning, 19th August. We've got 1.1m (about 4 feet) of SE swell with a 7-second period, energy at 214, but the wind is dead calm – glassy. For a beginner-friendly spot like Newcastle Beach, that's as clean as it gets. The surf will be small but fun, and crowds can be common here. Just remember, it's a beach and reef setup, so the short period won't give much power.
After that, Thursday 20th and Friday 21st offer small clean waves with light offshore winds, but the swell drops to 0.8m (3 feet) or less, and energy falls below 100. It's surfable but pretty ordinary.
Then there's a long quiet stretch until Sunday morning 23rd August, when we get another glassy morning with 0.8m (3 feet) S swell at 8 seconds, energy at 132. It's okay, but nothing special.
The last week stays small and messy, with onshore winds and weak energy, until the very end of the forecast. Saturday 30th August sees a huge jump – 5.0m (16 feet) from the S with a 13-second period and massive energy of 14754, but the wind is onshore and conditions are poor. That's for experts only, and even then it's a messy, dangerous situation. Sunday 30th still has 2.5m (8 feet) from the SSE with moderate energy, but again, onshore winds mess it up.
Bottom line: if you want a surf, hit that Wednesday morning glass-off. The rest is a waiting game.
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.
