The Lowdown
Alright, Rusty here, let’s break down what the ocean’s got cooking.
So the main spot on the menu for the next couple of weeks is Tongo Reef. It’s a reef break for advanced surfers only, and it’s fully exposed. There isn’t much action for a couple of days right at the start, but things get rolling properly on Friday, August 28th, with a solid, long-period southwest groundswell. That’s a real pulse of energy.
The absolute standout is gonna be Thursday, September 3rd. The morning and afternoon are the ones to save. You’re looking at a 5ft to 6ft SW swell with a 17-second period – that’s proper long-period groundswell, packing a ton of power. The combined energy is super high (1596 and 1902). For a reef like this, that’s what you want – it’s gonna line up and be heavy. The wind is a gentle breeze from the SSE and S, sitting cross-offshore, so the faces will be clean and hollow. That’s expert territory, no doubt – 6ft on a reef with that kind of period is serious. The water is also weird: it’s way warmer than usual for this time of year, with an anomaly over 4°F, so you’re in for some warm bathwater.
Leading up to that, the surf is mostly just so-so. The wind stays cross-off from the south, keeping things clean, but it’s not glassy. Saturday and Sunday, August 29th and 30th, have waves in the 4ft to 5ft range, but the energy is dropping off from the earlier pulse, and it’s just average. The first week is a slow climb to that Thursday peak.
After the 3rd of September, the swell backs off through the 4th and 5th, still offering 5ft to 6ft surf, but the quality is not as good. Still clean, but not the same. There’s another decent window on Thursday, September 10th, with a 5ft SW swell and a long 16-second period, plus light offshore wind and a gentle breeze. That morning holds moderate energy (1084), so it’s worth a look for the experienced crew.
Overall, once the surf starts on August 28th, there aren’t any big gaps, but most days are just okay. The real highlight is the 3rd of September – that’s the one. The rest of the time, you’ll get clean, consistent waves for the advanced crowd at a reef that can get a bit busy, so plan for company. And with that long-period energy, this spot will handle it way better than a beach break, so the shape should be juicy. Just don’t paddle out if you’re not ready for a powerful, solid reef break.
Rusty out.

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.
