The Lowdown
Righto, let’s have a look at what’s cookin’ for Tongo Reef over the next couple of weeks. Straight up, this is a reef setup that needs a decent push from the south-west to get goin’ proper. It’s an advanced wave, so we’re talkin’ hollow, fast, and no place for learners.
We’ve got a steady run of swell from the SW direction, but the wind is stuck in a cross-off pattern from the SSE and S nearly the whole way through. It’s not ideal offshore, but it’s clean enough. The real story here is the water temp – it’s sittin’ at a balmy 78°, which is a massive 8° warmer than usual for this time of year. That is seriously wild. You won’t need a thick suit at all.
Now, the first few days – Tuesday 1st September through to Thursday 3rd – are small to medium-ish. The swell bumps up from 3ft to 6ft by Thursday afternoon, with a long period of 17 seconds, giving that reef some proper grunt. The combined energy hits 1885 (moderate to strong) by Thursday arvo. That’s gonna be the pick of the early period. The wind is light enough from the south at 15 km/h, keepin’ the surface tidy. It’s a standout – but only for experienced crew. That 6ft on a reef with a long period will be pitchy.
From Friday 4th through to Tuesday 8th, we hover in the 4ft to 6ft range, but the period drops back to 14-16 seconds. It’s still surfable, but the energy backs off, especially by Sunday 6th. Crowds are “sometimes” here, so you might have company, but it’s not a circus.
The middle of the run, Saturday 12th, looks flat – just 3ft, short period, and barely any energy (420). That’s a write-off. Then Sunday 13th comes back with a little bump to 3ft, okay for a grovel.
The second week gets smaller again. From Monday 14th through Wednesday 16th, we’re back to 2ft – 3ft. The period on Wednesday 16th spikes to 23 seconds on a tiny 2ft SSW swell – that’s a very long period but almost no height, so it’ll be fat and slow. Not worth the paddle.
Overall, the best on offer is Thursday 3rd September afternoon: 6ft, SW, 17 seconds, clean cross-off breeze, energy of 1885. That’s the one to aim for. The rest of the window is a long, slow fade into small, weak waves. If you’re a beginner, it’s too big for you on that Thursday, and after that, it’s too small for anyone to get excited about. This stretch looks more like a kite-surfing breeze than a paddle session on most days.

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.
