The Lowdown
Alright, let’s talk Tongo Reef in feet and Fahrenheit. This is an advanced reef break, and the next couple of weeks are going to be a slow burner. The water is sitting at a very unusual 79°, which is about 10° warmer than normal—you won’t need much rubber.
First surf is Saturday afternoon, September 12th. Swell is 5ft from the SSE with a short 8-second period. Energy is moderate at 496. Wind is SSE at 12 mph, cross-off, so it’ll be clean, but the quality is marginal—more of a paddle than a session.
Sunday the 13th, swell picks up to 5ft, still SSE and 8 seconds. Energy hits 592 in the morning, 666 in the afternoon. Wind goes to 19 mph in the afternoon, still cross-off. Clean, but nothing special.
Monday the 14th is where it gets interesting. Swell swings to the SW with a long 17-second period—proper groundswell. Size drops to 3ft in the morning, then 4ft in the afternoon. Energy jumps to 1027 in the afternoon, which is strong. Wind is S at 12 mph, cross-off. That long-period SW groundswell on a reef is a good combo. Best day of the first week.
From Tuesday the 15th through the next week, it’s a steady run of SW swell between 3ft and 4ft, periods slowly dropping from 16 seconds down to 12 seconds. Energy stays moderate, mostly 300 to 700. Winds are cross-off or light cross-shore, so the surface is clean. Consistent but not epic.
The standout is Saturday, September 26th, morning. Swell is only 2ft, but it’s a long 18-second period from the SW, and energy is strong at 688. Wind is light from the S at 9 mph, cross-off. Forecast says “expect very good surf conditions.” For a reef, that long-period groundswell with clean conditions will produce smooth, well-shaped waves.
Sunday the 27th is also good: 3ft to 4ft SW swell, 13-second period, light winds—6 mph in the morning. Both sessions are flagged as very good, with energy around 690 to 754. A solid end to the outlook.
No big swell here—stays under 5ft the whole time, so it’s fine for experienced surfers. Crowds are possible but not likely given the modest quality most days. The long-period SW groundswell days will have proper shape and longer lulls between sets.

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.
