The Lowdown
Alright, mates, Rusty here. Let’s talk about what’s on offer for Tongo Reef over the next couple of weeks. It’s a bit of a strange run, to be honest. We’ve got a solid, long-period groundswell filling in from the southwest, which is exactly what this reef wants, but the ocean just isn’t playing nice for most of it. The winds are pretty much constantly cross-offshore, which keeps things clean, but the swell height just isn’t there to make it worthwhile. It’s going to be a grind for the first week or so.
The opening days, starting from Friday the 14th, look pretty lackluster. We’ve got around 5ft of SW swell with a very long 16-second period, so there’s plenty of energy moving through the water (1423), but it’s just not translating into good surf at this spot. The tides are looking questionable and it’s just a bit of a mess. The swell drops off slowly over the weekend and into next week, getting down to around 3ft to 4ft. The wave quality stays poor, all with that cross-off wind. This isn’t the time to be paddling out. Save your energy.
Now, there is one bright spot, and it’s a bit of a late call, but it might be worth circling on the calendar. On Friday the 21st of August, things finally shift. We get a lighter offshore breeze, from the ESE, and the swell, while smaller, is still a long-period SW groundswell. The forecast says “expect very good surf conditions” for the morning. It’s a much smaller 3ft, but that period is still a hefty 14 seconds, and with the wind finally swinging offshore, the reef will be clean and lined up. This is the standout, the one real window of quality in the whole period. It’s the only morning that looks worth getting out of bed for. The winds stay light for the afternoon too, and while the swell bumps up slightly to 4-5ft, the period drops off to a short 9 seconds, so the morning is the time.
After that little tease, things just fade away again. The second week sees the swell drop right down to an inconsistent 2ft, with energy falling away. It’s a lot of nothing, to be frank. The long-period SW swell is still trying to push through, and there’s another hint of a better day on Friday the 28th, with 4ft and a 14-second period, and the forecast is a bit more promising. But that’s two weeks out, so treat it as promising but far from certain. For a reef break that likes the size and power, this run of small, junky waves is a bit of a bummer. If you’re an old hand and just want to get wet, there’s always something to ride here, but for a decent session, your best bet is that Friday morning on the 21st. Don’t sleep on it.

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.
