The Lowdown
G’day, I’m Rusty, and I’ve been staring at charts for this spot all week. Let’s talk about Tongo Reef (Tongo-Reef). This is a solid reef setup, exposed to the south, and it’s been firing up a consistent run of groundswell. The water temp is sitting at 78°F right now, which is much warmer than normal for this time of year – a full 9°F above the long-term average, so you’re looking at pretty unusual warmth. Don’t expect a wetsuit thicker than a springy.
The first couple of days are a bit of a tease. Wednesday the 26th of August is small and marginal – we’re talking 2ft to 2ft on a very long 18-second period SW swell, but the energy is weak (401). The cross-off SSE wind keeps it clean, but honestly, it’s not worth paddling out for. Thursday the 27th perks up a little, with 2ft to 3ft SW swell, the period still long at 19 seconds, and the wave energy climbing to 558. The morning looks promising with a gentle S breeze and clean conditions, but it’s still small. The real standout arrives Friday the 28th of August. The morning brings 6ft SW swell with a 16-second period, the energy surging to 1543, and the wind is a gentle S cross-off. That’s excellent surf for experienced surfers – clean, powerful, and that reef will handle the long period beautifully. It’s a little too big for beginners, but for anyone with a bit of time in the water, this is the session to chase. Expect crowds sometimes, as this spot can get a bit of attention.
The energy drops a notch on Saturday the 29th – 5ft SW swell in the morning, still a solid 14-second period, and the energy is 1009. Another good morning with clean conditions, but the afternoon gets a bit lumpier. Sunday the 30th fades into the 4ft range, and the period drops to 13 seconds, with a moderate S breeze. It’s still surfable but nothing special. The first week closes out with a steady decline, and by Monday the 31st, we’re at 4ft and 12-second period, energy down to 419. The reef is still clean, but the punch is gone.
The second week kicks off with a pulse on Tuesday the 1st of September – 3ft SW swell, but the period jumps back to 17 seconds, and the energy is 722. The wind is a moderate S cross-off, so it’s clean, but small. Wednesday the 2nd is more of the same, 3ft to 3ft on a 15- to 18-second period. Then Thursday the 3rd of September brings a noticeable uptick: 5ft to 6ft SW swell, 17-second period, and the energy rockets to 1683. The morning is clean with a light SE breeze. This is another standout for the week ahead – a bit further out, so keep an eye on the forecast, but it’s promising. Friday the 4th holds at 5ft to 6ft, 15- to 16-second period, energy around 1596, with a moderate SSE cross-off. Clean but a tad windier. Saturday the 5th drops to 4ft to 5ft, and Sunday the 6th fades to 4ft, with the period settling at 13 to 14 seconds. The last real highlight comes on Tuesday the 8th of September – 5ft SW swell, 16-second period, energy 1464, and a light SSE cross-off. That’s excellent surf for experienced surfers, clean and punchy. The week trails off with 5ft to 4ft through Wednesday the 9th and Thursday the 10th, but the energy backs off to 985 by Thursday afternoon.
Overall, your best bets are Friday the 28th of August and Thursday the 3rd of September for the bigger, cleaner, longer-period SW groundswell. The long period means the waves will have plenty of shape and power, but at a reef break like this, it’s a dream. Just be aware that crowds are possible on the standout days. The wind stays mostly cross-off through the whole period, so the surface is usually clean. The long 16-plus-second periods on the bigger days mean the sets will be spaced out, making paddling out a bit easier, but the waves will be grunty. If you’re a beginner, stick to the smaller days around 4ft or less – the 6ft to 6ft stuff is for the experienced crew.
That’s the story from here. Stay stoked.

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.
