The Lowdown
Alright, let’s switch gears to feet and miles per hour.
First few days are a wash. Swell’s around 4ft, but the cross-offshore wind is a pain, and the energy is just mediocre. Water temp is normal for this time of year. You’re looking at marginal surf from the 17th through the 20th, with a moderate breeze. Not worth rushing out.
Then we hit a real dead spell on the 21st and 22nd. Swell drops to barely 2ft, and the energy is pitiful (260 to 77). That’s a total flat patch.
Now, here’s the good news. The 23rd shows a pulse building with a massive 24-second period. The energy is climbing (701 to 837), but it’s still a bit raw. The real standout is Sunday, July 26th.
That morning, the wind goes glassy-light from the east at just 3 mph, blowing offshore. You’ve got a clean 4ft swell from the south-west with a 19-second period. The energy is a beast at 2214. This is your day. Tongo Reef is going to be a ripper, with clean, long lines. It’s a reef, so it’s for the advanced boys, but man, it’ll be worth it. The afternoon stays okay but picks up a little cross-shore bump.
The 27th still has strong energy (2285) with 5ft swell from the SW, but the wind is more side-offshore, so not as clean as Sunday. After that, it’s a slow fade into the end of the month. The 31st has a crummy, short-period 4ft from the south with only 8 seconds – back to mushy.
So, same story: the first week is a dud, but that Sunday the 26th is your one chance at glory. Don’t miss it.

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.
