The Lowdown
Alright folks, Rusty here. Let's break down what's cooking for the Tongo Reef stretch. There's a solid run of swell lined up, but it’s not all perfect. The water is a warm 78°, which is much warmer than usual for this time of year, so leave the thick rubber at home.
Our best bet kicks off on Thursday, August 27th. It’s not massive, with a 3ft SW swell, but that 19-second period is something special. That's proper groundswell energy, hitting the reef with 916 combined energy. It's clean with a light cross-off breeze, so it won't be a messy lineup. If you can get out there, those long-period lines will be for the advanced crew only.
The real standout comes on Friday, August 28th morning. The swell jumps to 6ft from the SW, with a 16-second period and a massive 1543 combined energy. The wind is a gentle cross-off from the SSE, keeping things clean. This is the pick of the early window. The afternoon holds similar size and power at 6ft and 1751 energy, but you won't need to rush.
We get another excellent window on Thursday, September 3rd afternoon. The swell is a solid 6ft from the SW, riding a 17-second period, and the combined energy is a beefy 1727. The wind stays light and cross-off, making for excellent conditions, specifically for experienced surfers. That long-period groundswell on a reef setup is a dream.
Then again, on Tuesday, September 8th morning, we see another top-quality window. A 4ft SW swell, 17-second period, and 1301 combined energy. It says excellent conditions for experienced surfers, and with that clean, gentle cross-off breeze, it’s going to be worth the wait. That's your long-range promise.
Most of the days in between are marginal, with moderate cross-off breezes, but the swell is consistent enough to keep the reef alive. Don't expect much on August 31st or September 1st as it drops right off. The window from the 5th to the 7th of September looks average, with smaller swell and messy conditions. Things really pick back up from the 8th onwards.
Tongo Reef is a consistent spot, so even on the weaker days, there'll be something to ride. The crowds can get on it sometimes, so be early. If you're a beginner, keep an eye on those 6ft+ days, as that's getting a bit big. For the experts, the 6ft to 6ft days with those long, perfect periods are as good as it gets.
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.
