The Lowdown
G’day, Rusty here. Look, I’ll level with you—this Tongo Reef outlook is a bit of a mixed bag. It’s a reef break, so it’s for advanced surfers only, and it’s fairly consistent, but the crowds can show up sometimes. The water temperature is about average for this time of year, nothing wild there. We’ve got a long stretch ahead, but it’s not all firing.
The overall pattern is a whole lot of marginal conditions with cross-off winds and moderate breezes. The swell energy is moderate most of the way, with a few spikes, but the wind is rarely doing us any favours. The best on offer is honestly just a couple of days where it gets a little cleaner or the swell has a bit more grunt.
From Monday 10 August, we’re looking at a 3ft SSW swell, but it’s a long 14-second period. The energy is moderate (852) with a cross-off SSE breeze at 12 mph. The tide or something is making it marginal, so it’s not a standout. That long period groundswell is better suited to a reef like this, but the cross-off wind keeps it from being clean. The afternoon bumps to 1001 energy, but still cross-off and marginal.
Tuesday 11 August is a write-off with 3ft and 2ft swells, both cross-off, and a fresh breeze on the morning. The energy drops to 757 and 554. Not worth paddling out.
Wednesday 12 August sees a shift to a 4ft SSE swell, but the period drops to 8 seconds—short-period, junky energy. The energy is 452 and 371, weak. Still cross-off winds. No good.
Thursday 13 August picks up a bit: 4ft to 4ft SW swell with a nice 18-second period. The energy jumps to 1137 and 1327, moderate. But it’s still cross-off winds. The swell is there, but the wind is messing with the shape. If you’re desperate, it’s the best of a bad week.
Friday 14 August is the same story: 5ft SW swell, 16-second period, energy around 1458. The wind is still cross-off, though, so it’s not the clean session you’d hope for. The afternoon clears up but the wind stays cross-off.
From Saturday 15 August through to Tuesday 18 August, the swell drops to 4ft to 4ft, with energy falling to 685-1161. The wind is still cross-off, and the scores are low. A real flat spell.
Then on Wednesday 19 August and Thursday 20 August, we get a 6ft to 5ft SSE swell, short period around 9 seconds. The energy is moderate (792 to 562). Thursday morning finally sees a switch: a light offshore SE breeze at 9 mph, and the forecast says “expect very good surf conditions.” That’s the standout. The swell is 5ft from SSE, period 9 seconds—short but with offshore wind on a reef. It’s going to be clean and punchy. For advanced surfers, this is the one. The afternoon goes back to cross-off, so hit it early.
After that, Friday 21 August to Tuesday 25 August fades out. Swells drop to 2ft to 3ft, with some longer periods (15-21 seconds) but very little size. The energy stays moderate (510 to 1262), but the wind is cross-off again. One morning on 22 August has a gentle breeze, but the swell is a tiny 3ft. Not worth it.
So, to wrap it up: Thursday 20 August morning is the pick. A 5ft SSE swell with offshore SE wind on a reef—clean, punchy, and for the experienced crew. The rest of the 16-day window is a grind of cross-off winds and marginal conditions. Stay patient.
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.
