The Lowdown
Alright folks, Rusty here, checking the charts for what's headed our way. It's a slow start, but if you're patient, there's some serious potential waiting for you.
Right now, it's pretty flat. The next few days are showing tiny waves around 2ft to 2ft from the SSW/SW with a long period, but the juice just isn't there (combined energy of 167). The wind is a steady cross-off from the south, keeping the surface clean, but there's no power behind it. The water is a weird 78°, which is way warmer than normal for this time of year – a solid 8° above average. Strange, but nice for a paddle.
Thursday, August 28th is when the switch flips. We get a strong push of swell, jumping to 6ft on the Friday morning from the SW, with the combined energy ramping up to a powerful 1543. This is expert territory, way over 5ft, so leave the foam boards at home. The wind stays a gentle cross-off, and the period is a proper 16 seconds – that's real groundswell. Tongo Reef, being a reef break, is the perfect setup for this kind of long-period energy.
The one to lock in, the absolute standout, is Thursday, September 3rd. The Friday morning session is showing 5ft of SW groundswell with a period of 17 seconds and a very strong combined energy of 1662. The wind is light and cross-off, so it's looking absolutely firing and clean for the advanced crew. That's your best chance for the whole outlook.
After that peak, the swell holds in the 5ft to 6ft range for a few more days, but the wind picks up a bit during the afternoons. Still surfable, just not as perfect. By the second week, from September 6th onwards, the swell fades back to around 4ft. The energy stays moderate and the wind is still favourable, so there will be fun waves, just nothing to write home about. Tongo Reef is for experienced surfers and it can get busy when the swell hits, so expect to share the peak.
For now, rest up. The real action is waiting for us in the first week of September.
Stay stoked,
Rusty

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.
