The Lowdown
G’day, Rusty here.
Alright, let’s chew the fat on Long Reef for the next couple of weeks. Fair warning – it’s looking pretty ordinary for the most part. The first real chance you’ll have to get wet is this Friday morning, the 14th, but even then it’s a modest offering.
Right now, there’s a bit of swell around, but Thursday is a total washout – messy wind, poor conditions, nothing happening. Thursday afternoon the swell bumps up to about 5 feet from the south, but it’s onshore and ugly.
Friday the 14th morning is where I’d aim. It’s not epic, but there’ll be clean 4 ft south swell with a light offshore breeze from the west. The swell period is a short 9 seconds, so it’s not got a ton of punch, but it’ll be clean and rideable. The combined energy is moderate at 266. Water temp’s at 62°F, which is about a degree and a half colder than normal for this time – you’ll want a good wetsuit. The breeze goes a bit cross-onshore in the arvo, so hit it early.
After that, it’s a dry spell. Saturday morning (15th) is marginal with 4 ft from the south and some cross-shore wind, but it’s not worth the drive. Sunday through to the following Thursday morning (20th) is mostly small, onshore, or just plain ordinary. There’s a quick flash on Wednesday the 19th morning with 4 ft from the east-southeast and light cross-offshore wind making things clean, but the swell’s weak and short-period – not worth chasing. Thursday the 20th morning is similar, small and clean but barely enough energy (combined energy of 105) to get your heart racing.
From the 21st onward, it’s a long, slow fade into tiny swell – most days seeing 1 ft to 3 ft, with the odd clean morning but zero push. There’s a slight pulse around the 23rd (Sunday) and 24th (Monday) with clean 3 ft from the east-northeast and offshore winds, but the energy is weak to moderate at best. The 24th afternoon goes glassy, which is nice, but the swell’s only 3 ft with a mediocre 10-second period. Nothing to phone home about.
Now, Thursday the 27th – that’s where things get serious, but not in a good way for a paddle surfer. The swell jumps to 7 ft from the south, with a long 11-second period and a combined energy of 925 – that’s strong. But the wind is a fresh 22 mph cross-offshore, which will tear it up. The following day, Friday the 28th, sees even more energy (1092) with 7 ft south swell and a 12-second period, but again, strong onshore winds at 25 mph – this is a full-on washing machine. At that size and wind, Long Reef is going to be a windy, lumpy mess. I’d honestly say this setup looks more interesting for kite surfing than paddle surfing – the swell energy’s there, but the quality is gone.
So, what’s the pick? Friday morning the 14th is your best bet – clean, small fun waves for a few hours before the wind switches. After that, the *only* other thing worth a look is Monday morning the 24th – glassy conditions and clean 3 ft east-northeast swell, perfect for a longboard but not much else.
The rest of the 16-day run is largely flat, onshore, or blown out. There’s a gap of about five days of barely surfable slop in the middle. It’s not a classic winter run, that’s for sure. Keep an eye on the charts though; it tends not to stay poor for long around here.
Rusty.

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