The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming our way for Singleton over the next couple of weeks. There’s some serious energy on the horizon, but the wind is going to be the boss for most of it. We’ve got a nice clean window to start, but after that, it gets stubborn.
We kick things off on Thursday, August 20th with a solid pulse. It’s a morning mission only. Singleton is seeing a solid 8ft swell from the WSW, with a very long 16-second period. That’s proper groundswell. The water temp is sitting at 64°F, which is totally normal for this time of year. The best part? Glassy conditions with zero wind. The combined swell energy is pumping at 3529 (moderate to strong), so there’s heaps of push. This is proper, thick, lined-up surf but it’s steep and powerful, so it’s strictly for experienced surfers. A standout session if you’ve got the skills.
Friday the 21st morning continues the run. Clean conditions again, glassy with a light ENE breeze. Swell eases slightly to 7ft, still from the WSW with a 15-second period – excellent quality. Energy is still solid (2120). This is another top-notch morning for confident surfers. Saturday morning the 22nd keeps the glassy theme going with a 7ft swell and the same long 16-second period. Energy down a touch (2068) but still plenty of grunt. These three mornings are the clear highlights of the outlook.
Things get rougher from Saturday afternoon onward. The wind shifts to a strong cross-onshore and the surf quality drops off quickly. Sunday the 23rd and Monday the 24th have some clean-ish moments, but the wind and chop make it unreliable. By Wednesday the 26th, the wind cranks up to 25 mph with rain and thunderstorms, making it a total mess. The swell spikes to 12ft, but the wind blows it out completely – that setup looks far more interesting for kite surfing than paddle surfing.
We get a brief reprieve on Friday the 28th morning. The wind drops to glass again (0 mph from the east), and the swell is a clean 7ft from the WSW with a 13-second period. Energy at 1316. Another clean, powerful morning for experts. After that, it’s back into the wind. The end of August and start of September brings more strong onshore winds and building swell, but with the chop and lump, it’s not worth paddling out. There’s a couple of marginal windows on Tuesday the 1st and Friday the 4th of September, but the wind is never fully right.
So, the standout windows are the mornings of Thursday August 20th, Friday August 21st, and Saturday August 22nd. Clean, proper groundswell, and consistent. The rest of the period is either blown out or too rugged for anything but the most die-hard.
Stay safe out there.
Rusty.

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