The Lowdown
Alright, this is a bloody ripper of a forecast, if you know what you're doing. Look, I'm not gonna lie to you, the opening days are for the brave. We’ve got a serious pulse of energy coming through, but it's not messing around. The combined swell energy is huge, hitting 6388 on Tuesday, and that's a massive number. The water temp is sitting at 64°F, which is about 2°F cooler than normal for this time of year, so it's a bit fresh but not unusual.
The standout by a country mile, if you've got the skills, is Singleton itself. This spot is exposed and fairly consistent. The big news is a clean, glassy window on Thursday morning, August 20th. The wind is dead calm, the swell is a solid 8ft from the WSW, and it's a proper long-period groundswell of 16 seconds. That combination is rare. The energy is still very strong at 3594, so these won't be small waves. For a confident experienced surfer, this is the best session on offer. The offshore wind direction is ENE for this break, so the glassy conditions are a massive bonus.
Before that, the swell is just too damn big. Tuesday and Wednesday see 12ft and 10ft waves with strong winds, making it a real handful. Friday morning, August 21st, is another glassy gem with a 7ft WSW swell and 15-second period, but the energy is still high at 2087. It's a good option for the experienced crew, but Thursday has the edge for quality.
The second week gets a bit messy. We have a stretch from Tuesday, August 25th, through to Friday, August 28th, where the wind is howling, mostly onshore, and the quality drops right off. A couple of those days have wind speeds over 25 mph, making it pretty much a write-off for surfing. You'd be better off kiting on that Tuesday the 25th if you're into that.
Things start to look up again on Sunday morning, August 30th. We get another glass-off with a 6ft W swell. The period is a nice 15 seconds, and the energy is a moderate 1371. It's a solid, clean option for the experienced surfer, but the combined energy is lower than Thursday the 20th, so it won't have the same punch.
The very end of the run, on Tuesday, September 1st, sees a big 10ft W swell pop up, but with a shorter 14-second period and cross-shore winds. It's going to be a big, tricky wave, not the clean, lined-up beast we saw on the 20th. For my money, lock in the morning of Thursday, August 20th, that's the one.

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.
