The Lowdown
G’day, it’s Rusty.
Alright, looking at this stretch, we’ve got a solid run of surf on the horizon for Tongo Reef, but it’s not all blue skies and barrels. The first couple of days are a bit of a write-off with messy, cross-shore wind and poor conditions. But hang in there, because once we get past that initial bump, it cleans right up for some proper sessions.
We start off a bit rough on Wednesday the 5th. There’s some swell in the water, around 3ft from the southwest, but that cross-shore breeze and cross-chop are making it messy and not worth your time. The energy is moderate at 470, but the quality just isn’t there.
The real action kicks off Thursday morning, the 6th. The wind swings to a gentle cross-offshore breeze, the water cleans up, and you’ve got a nice 2.6ft SSW groundswell with a long 17-second period. This is where it starts getting good. The energy jumps to a solid 652, and the surf is looking clean. That afternoon is also decent, holding at 3ft with a 16-second period.
Friday the 7th is a standout. The morning brings a light offshore breeze, and the swell pushes up to 3.9ft from the SSW with a 15-second period. The energy is pumping at 751, and the conditions are textbook clean. This is your best bet for the first week. The afternoon stays just as good, though the wind goes a touch cross-off.
Through the weekend, Saturday the 8th and Sunday the 9th, we’re still in the zone. Saturday has consistent 3.6ft SW swell with clean conditions and moderate energy in the 520s. Sunday morning dips a little to 2.6ft, but the afternoon comes back up to 3.6ft with a 15-second period and energy at 689. All good, clean surf.
Monday the 10th is another highlight. There’s a nice, gentle offshore breeze on the morning session, 3ft of SSW swell, and energy jumps to 785. It’s clean and lined up. The afternoon gets a bit stronger wind and the tide looks questionable, so the morning is your window.
From Tuesday the 11th into Wednesday the 12th, things get a little less appealing. The wind picks up to a moderate breeze, and while it’s still cross-offshore, the surf gets a bit lumpy. The swell also drops off, and we see some short-period windswell mixed in on Wednesday, with 5.6ft at a short 7-second period. That’s just messy and not a great look for the reef. The energy also drops into the 380-550 range.
Now, here’s where things get interesting. Starting Thursday the 13th of August, we see a significant jump in energy. The numbers go from moderate to strong, with the combined energy hitting 1352 in the morning and 1495 by the afternoon. The swell is 4.3ft to 4.9ft from the SW with an 18-second period. This is proper groundswell. The conditions are clean, but the guidance calls it marginal on tide, so you’ll need to pick your moments. This is a powerful, long-period swell that will work well on this exposed reef, but be aware that the long period can make it break a bit straight at times. This run continues through Friday the 14th, with similar 4.9ft waves and strong energy around 1243-1301. This Thursday-Friday combo is the peak of the whole window – it’s got the size, the energy, and the clean winds. This is for experienced surfers, as the size is getting up there.
After that, things taper off through the weekend of the 15th and 16th, with 3.6ft to 3.9ft of SW swell and moderate energy in the 700-970 range. Still surfable, still clean, but the magic is gone.
The second week is a bit more of a mixed bag. We see another pulse building towards Wednesday the 19th and Thursday the 20th. The energy climbs back up to solid three-digit numbers, over 1000, with 4.6ft to 4.9ft SSW swell at 14-15 seconds. The wind stays gentle and cross-offshore, keeping it clean. These late-period swells look promising, but like all long-range calls, they’re a bit less certain. There’s good potential there for another solid run.
One thing about this spot – it’s a reef break, and it’s only for advanced surfers. With the swell over 5ft on those peak days, it’s definitely too big for beginners. And when it gets over 8ft, you can bet only the experts will be out. Crowds are sometimes a factor here, but with the quality of surf on offer, a few more people in the water is a price worth paying.
Also, the water temp is a real talking point. When you paddle out at Tongo Reef, it’s a balmy 78.4°, which is a whopping 9° warmer than average for this time of year. That’s very unusual – you’ll be surfing in boardies or a thin suit for sure.
So, to sum it up: get out for Friday the 7th for the cleanest, most manageable session. And mark your

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