The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for this patch of reef.
Right off the bat, I gotta be straight with you – the next week or so is looking pretty average. The swell is small, the wind is a persistent cross-off, and we’re just not getting the juice. The combined wave energy is weak, sitting mostly in the low hundreds to mid hundreds (around 279 to 692). The water is a toasty 78°F – that’s 9°F warmer than usual, which is a real oddity for this time of year. You’ll be sweating in your wetsuit, that’s for sure.
Saturday the 22nd through Thursday the 27th is a real grind. Waist-high dribble from the SSE, with periods around 9 to 19 seconds. That long-period groundswell from the SW on the 23rd and 24th is enticing on paper, but at 2 ft to 3 ft, it’s just not wrapping in with enough height. The wind is a steady cross-off, so it’s not blown out, but it’s hardly a standout. This is a quiet spell for Tongo Reef.
Friday the 28th of August is where things start to wake up. The swell jumps to 6 ft to 6 ft from the SW, with a period of 16 seconds. That’s proper groundswell energy. The combined energy jumps to 1546 and then 1711 – that’s a solid push. The morning looks clean with a gentle cross-off breeze, but the afternoon gets a slight cross-chop. That morning session is the one to aim for. This is still a spot for the experienced crew; 6 ft on a reef break is not for beginners.
We then have a bit of a lull through the weekend, with 5 ft and 5 ft swell dropping back down, before a real beauty of a window appears.
Thursday the 3rd of September is the standout in this whole outlook. The swell is 6 ft to 7 ft from the SW, with a period of 18 seconds – that’s very long-period groundswell. The combined energy is a massive 2588 and 2669. That’s powerful. The wind is light and cross-off, or a gentle breeze. This is excellent surf for experienced surfers. The long period will make the reef lines stack up and peel beautifully. This is your best bet.
Friday the 4th holds onto that energy, with 6 ft to 6 ft swell and still clean conditions. It’s a strong tail end to the swell.
After that, the size fades back to 5 ft and below through the first week of September, with the energy dropping below 1100. The wind stays cross-off, so it’s not a total washout, but the second week is definitely the weaker half.
Overall, the real standout is that Thursday the 3rd – mark it in your calendar. It’s a long way out, so the forecast could wobble, but right now it looks like the best push of the month.

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.
