The Lowdown
G’day, Rusty here. Let’s run through what’s cookin’ at Tongo Reef for ya.
The real action is upfront. Starting Thursday the 3rd of September, we get a solid SW groundswell pushin’ 6 ft with a long, drawn-out 17-second period. The combined energy is strong at 1882. This is proper reef grind, but the wind is cross-off from the south at 12 mph. Not glassy, but clean enough for the skilled crew. The water temp is a weird 78°, runnin’ about 9° warmer than normal for this time of year. The reef should handle that long-period energy alright, but with that kind of period, the waves’ll be powerful and lined up—strictly for advanced folks. Friday the 4th keeps the size goin’ with a 6 ft SW swell in the mornin’ (energy 1862) and 6 ft in the arvo (energy 1595). Winds stay cross-off, so it’s still clean. That first 48 hours, starting Thursday, is the clear standout.
Saturday the 5th drops to 5 ft and 5 ft, same SW direction, period down to 14 seconds. Energy’s still moderate at 1097 and 983. Wind holds cross-off. Still surfable. Sunday the 6th slides further: 4 ft in the mornin’, then 4 ft in the arvo. The afternoon has a “very good” note, but energy’s down to 698.
From Monday the 7th onward, it goes small. Heights between 2 ft and 5 ft for the rest of the run. There’s a brief blip on Wednesday the 9th with a 5 ft SW swell and energy of 1441, but wind’s still cross-off and conditions look marginal. The second week—say from the 10th to the 18th of September—is mostly tiny, with swells under 3 ft most days. There’s a couple of super long-period pulses on the 16th and 17th—like a 23-second interval from the SSW with only 2 ft and energy at 819, and a 21-second period—but with no size to back it up, you’re just watchin’ the horizon.
Best bet is that first window, Thursday the 3rd and Friday the 4th. It ain’t perfect with that cross-off breeze, but the size, period, and energy make it the clear winner. Tongo Reef can get some company, so keep an eye out.
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.
