The Lowdown
Hey, Rusty here. Let’s talk Newcastle Beach. The next 16 days look like a bit of a struggle, so I’ll break it down.
Wednesday the 16th is a no-go: a solid 12 ft south swell but with a 19 mph cross-onshore. That’s a washing machine. Thursday the 17th is still messy with 12 ft and bumpy winds. Skip it.
Your first real window is Friday the 18th, early morning. Swell drops to 4 ft from the south, but the wind goes light offshore from the WNW at 3 mph. Clean conditions, and the wave energy is moderate (338). The period is 9 seconds – nothing special, but it’ll be rideable. This is the best call of the whole outlook for most surfers.
Saturday the 19th morning is tiny – 2 ft from the south, but with a very long period of 17 seconds. At a beach break, that can be a bit too straight, but the wind is light cross-off and it’s clean. Wave energy is weak (276). Not a standout.
Sunday the 20th morning: 3 ft from the south, glassy, with 3 mph winds from the SW. Period of 11 seconds gives it some shape. Wave energy is moderate (323). For clean small waves, that’s the pick of the weekend.
Monday the 21st morning has 3 ft from the south, 13-second period, and a light offshore from the NW at 9 mph. Clean but small.
After that, it’s a dry spell until Thursday the 1st of October. That morning brings 4 ft from the SSE with a light offshore from the WNW, but the period is a weak 6 seconds – so it’ll be sluggish. The afternoon jumps to 6 ft from the SSE (10-second period) with light cross-on winds. Wave energy is 776 – moderate to strong – but the quality isn’t there.
Water temp is around 65°F, right on average for the season. Crowds are often at Newcastle Beach, so expect company on the few clean windows.
The only true highlight is Friday 18th early. Don’t bother with the rest unless you’re desperate for a paddle. There are long gaps with nothing worthwhile – the first two days are bad, and it goes quiet for over a week after the 21st. That’s pretty standard when the winds aren’t cooperating.
Rusty out.

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.
