The Lowdown
G’day, Rusty here. We’ve got a solid 16-day window ahead for Nyang-Nyang, but it’s a mixed bag of serious swell and a lot of onshore chop. Right now, there’s no surf on offer until the morning of Sunday, August 16, so we’ve got a short gap of nothing to worry about before things kick off.
The first real chance comes Sunday morning, August 16, with a 6.9ft SSW swell riding a very long 16-second period. The wave energy is strong (2156), but the wind’s coming from the ESE at 6 mph, making it a cross-shore breeze. The forecast flags dodgy tide conditions, so it’s not a clean winner. The water temp is about average for this time of year. From Sunday afternoon, the wind picks up to 12 mph and turns cross-onshore, chopping things up through the rest of the week. Monday morning, August 17, still has a 5.2ft SSW swell, but the cross-shore wind at 12 mph keeps it marginal. Honestly, the morning of Sunday, August 16, is the best on offer in the first week, but it’s not a standout because of the tide and wind concerns.
The real standout for me is the morning of Sunday, August 30. That’s when we see a 6.6ft SW swell with a very long 19-second period, and the wave energy is powerful (3433). The wind is a gentle breeze from the SE at 9 mph, but it’s cross-onshore, so still a bit choppy. The following Monday morning, August 31, is even bigger: 9.8ft SW swell, 17-second period, and massive energy (4991). The wind drops to a light breeze from the SE at 6 mph, still cross-onshore, but the size is something else. This is only for experts, as it’s over 8.2ft. The August 30 morning is the pick, with a promising long-period groundswell that’ll groove well at this reef break, though the cross-onshore breeze keeps it from being perfect. Crowds are possible at Nyang-Nyang, so keep an eye out.
The second week (from August 24) stays similar: moderate to large swells with cross-onshore winds, mostly marginal. The morning of August 27 has a 4.9ft SW swell with a 19-second period and a gentle cross-shore breeze, offering a slightly cleaner window, but still with dodgy tide conditions.
Overall, if you’re locked in, Sunday August 30 morning is your best bet – big, powerful groundswell, manageable wind, and a reef setup that’ll handle the long period. Just be ready for the crowd.

Information about the Nyang-Nyang Surf forecast
The above surf forecast table for Nyang-Nyang provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nyang-Nyang can be found by selecting the local surf guide option on the grey menu. Our Nyang-Nyang 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 (Nyang-Nyang) 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 Nyang-Nyang 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.
