The Lowdown
Right, let’s have a look at what’s brewing for the next couple of weeks. Only one spot on the radar worth talking about, and that’s Tongo Reef. It’s a reef break, takes a south swell best, and it’s pretty exposed. The water is a toasty 77°, which is much warmer than normal for this time of year.
We’ve got a bit of a slow start, to be honest. From Sunday the 30th of August right through the rest of that week, the surf is small and lacks any real punch. We’re talking swell heights under 4ft, and the energy’s moderate at best, with readings around 420 to 756. The wind’s cross-off, which is okay, but the waves are just not doing much. It’s marginal surf, really.
Now, hold on to your board, because Thursday the 3rd of September and Friday the 4th of September are where it’s at. The swell jumps up to a solid 5ft to 6ft from the SW, with a period of 16 to 17 seconds. That’s proper groundswell, mate. The energy ramps up big time, hitting 1889 on Thursday afternoon. Those are serious numbers. The wind stays cross-off, so it’ll be chunky, powerful, and clean. This is the standout window. That swell is a bit much for beginners, but for advanced surfers, Tongo Reef will be firing. Just keep in mind, with that long period, it’ll be breaking deep and fast, so it’s all about the take-off.
After that, the swell slowly fades through the second week. We’re back to 3ft to 4ft from Sunday the 6th onwards, with the energy dropping back into the hundreds. The wind remains cross-off, so it’s still ridable, but nothing like that Thursday-Friday peak. Things get really small by the 12th and 13th of September, with barely 2ft to 3ft of swell. There’s a bit of a pulse in the period on the 13th afternoon, with 18 seconds, but the height is tiny, so it’s more of a novelty than a session.
So, the clear winner is that Thursday the 3rd and Friday the 4th of September window. That’s your best shot for some real, powerful waves at Tongo Reef. Get 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.
