The Lowdown

G'day, it's Rusty here. We’ve got a mixed bag coming in over the next couple of weeks, with a few windows of real promise but plenty of ordinary days to sit through first. The early part of the outlook is pretty flat and uninspiring, so don't rush out the door just yet.

The first decent session shows up on the morning of Friday the 7th. At Long Reef, we’re looking at a small 2-foot south swell, but it's clean with a light offshore breeze from the west. The water is sitting at 63°, which is a touch below average for the time of year, so you might want a decent spring suit. The combined energy is weak (119), so it's more about getting a few grovelly turns than anything special. The afternoon goes cross-on, so forget it.

Saturday morning, the 8th, is a repeat of very small, clean conditions with that 2-foot southerly swell and a glassy offshore wind. The energy is still weak (111). It's surfable, but there's no power in it. The rest of the weekend and into the start of the next week is a write-off with messy winds and poor conditions.

Now, keep an eye on Tuesday the 13th. The swell starts to build properly. Thursday the 14th is the real standout. The afternoon session at Long Reef sees a solid 7-foot south swell, with a light offshore wind and very strong wave energy (1162). The conditions are rated excellent for experienced surfers. This is a proper groundswell with a period of 11 seconds, meaning proper lines and power. It's a reef break and exposed, so it'll handle it well. The water is still around that 63° mark. This is the one to pencil in. Crowds are possible here, so get in early.

Friday the 15th morning still has some size (4-foot south) but the wind starts to howl, and it gets messy quickly after that. There’s a big gap of poor conditions after that, with nothing worth paddling out for until the 20th of August.

Looking further out, the morning of Friday the 21st of August brings a fantastic setup. A 7-foot east-northeast swell with a very long 13-second period, and light offshore winds. The combined energy is strong (1398). This is a point-break style swell, and Long Reef is a reef, so it should hold beautifully. Again, this is for experienced surfers only as it's well over 8 feet. The next morning, Saturday the 22nd of August, also looks promising with a 10-foot south swell and clean conditions, but that's big, powerful, and only for the experts. These late-August standouts are promising, but they are still a way out, so keep an eye on the forecasts closer to the time.

Stay safe out there, and I'll see you in the lineup.

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.
