The Lowdown
G’day, Rusty here. Alright, let’s have a look at what’s coming up for Tongo Reef. This is a solid, exposed reef break that handles a south swell really well, and it’s a spot for the advanced crew only. The water temp is running pretty standard for this time of year, nothing out of the ordinary.
We’ve got a bit of a slow start right now. The best window for a proper session kicks off on Wednesday, the 16th of September, with the morning looking the pick. The swell is coming in from the southwest at 4 ft, with a long-period groundswell of 14 seconds, and that cross-off breeze from the south at 9 mph is keeping it clean. The wave energy is moderate (709). This is the standout of the whole run, no question.
The following days from Wednesday afternoon through to Tuesday the 22nd will see the size drop just a touch, mostly hanging between 3 ft and 3 ft from the southwest. The winds stay cross-off, keeping things clean, but the forecast scores are just not there for a top-notch session. The energy remains moderate (ranging from 400 to 830). It could be fun for a keen surfer, but there’s nothing that screams “drop everything and go.”
We hit a bit of a rough patch from the 22nd of September through to the 25th. The wind swings cross-shore and picks up, creating a bit of chop, and the surf quality drops. A few sessions on the 25th see a slight bump in height to 4 ft from the southwest, but the wind is still messy, making it less appealing for a paddle.
Now, heading into late September and the start of October, it gets interesting again. On Saturday the 26th of September, conditions look prime: a clean 3 ft from the south-southwest, light breeze at 6 mph from the south, and a long-period groundswell of 18 seconds. Wave energy is strong (823), and the forecast is very good. This is the second real standout – it’s a quieter crowd day, with only “sometimes” mentioned, so you might get more waves to yourself. For experienced surfers, this is a cracker.
During the last few days of September and into October, there are more clean, cross-off mornings, but the swell hovers around the 2 ft to 3 ft mark, still with respectable period. The morning of Thursday, the 1st of October, has a very good forecast with a 3 ft south-west swell at 16 seconds, light southeast wind, and clean conditions. Wave energy is moderate (521).
Overall, lock in the mornings of Wednesday the 16th of September and Saturday the 26th of September for your best bets. The reef handles the long-period swell beautifully, and with that offshore wind, Tongo Reef will be on.

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.
