The Lowdown
Alright, let me get this straight. It's a quiet start for sure, but we've got a nice run coming down the line later on.
Honestly, looking at the whole 16-day window, it's a slow burn here for Tongo Reef. The first few days are just not worth paddling out for. You’re looking at a real flat spell from Saturday the 29th of August right through to maybe Tuesday the 1st of September. That’s a handful of days with nothing doing, just small, weak swells and cross-off breezes that won't give you anything clean.
Now, things start to get interesting from Wednesday the 2nd of September. Wednesday afternoon is where we see the first glimmer of hope. We’ve got a 3ft SW groundswell rolling in with an 18-second period, carrying moderate wave energy (753). The wind is a gentle cross-off from the south, keeping the surface clean. It’s small, but that long period will give it some punch for the more refined boards.
The standout, the one you really want to circle on your calendar, is Thursday the 3rd of September and into Friday the 4th of September. Thursday morning sees the swell building to 5ft from the SW with a 17-second period, and the combined energy jumps right up to strong (1569). By Thursday afternoon, it's even bigger at 6ft, and the energy is pumping (1909). That’s a proper SW groundswell.
This is when Tongo Reef, an advanced-level reef break that's fairly consistent, will start to fire. The water temp is 78°F, which is much warmer than normal for the time of year, so you can get away with a spring suit or maybe just a rashie. Keep in mind, it can get a bit crowded here sometimes. That southwest swell lines up perfectly with what this break wants, and with a clean cross-off breeze, expect some lined-up, powerful waves. Because the period is long (over 15 seconds), these are proper groundswell lines, which a reef setup like this will handle beautifully. They might close out a bit at a beach break, but on Tongo, they’ll hold their shape.
Friday the 4th holds similar energy, with 6ft SW swell in the morning (1868 energy) before easing slightly in the afternoon. From Saturday the 5th onwards, the swell starts to fade slowly through the second week, but we still see some waist-to-chest high sets with clean conditions. The long-period swell sticks around, so there’s always a chance for a sneaky bomb set on the better tides.
If you’re a beginner, those days around the 3rd and 4th of September when the swell is over 5ft will be a handful, especially on a hollow reef like this. By the time it drops back to the 3ft to 4ft range in the second week, it'll be more manageable for intermediate surfers, still with that long-period quality.
So, the best bet is Thursday the 3rd and Friday the 4th of September. Get ready for a session that could be the best of the foreseeable future. Everything after that is smaller but still worth a look if you’re needing a fix.

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.
