The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window for Tongo Reef, and it’s a mixed bag of a forecast. The overall pattern is one of persistent cross-off winds and a lot of marginal conditions, but there are a couple of windows where things line up.
First up, the water is cooking. We’re talking 78° degrees, which is a massive 9° warmer than usual for this time of year. It’s properly tropical out there, so a steamer isn’t happening.
The first real chance to get wet is on Friday, August 7th afternoon. We’ve got some clouds, a 4ft SW swell with a solid 15-second period, and a cross-off wind from the SSE at 9 mph. The combined energy is moderate (737). It’s a bit of a tester, but the tide could be a factor. It’s not the standout, but it’s a start.
Saturday, August 8th morning is where it gets interesting. The sky clears, the wind drops to a light 6 mph from the SE, and it goes *offshore*. That’s a major positive. The swell is a clean 4ft from the SW, period still a healthy 14 seconds. The combined energy is moderate (523). This is your best bet for the early part of the week—clean, lined-up waves with light winds. It’s a genuine shout for a good session. The afternoon picks up a bit of breeze, turning it cross-off again.
Sunday the 9th morning is another decent option with a similar set-up: 3ft from the SSW, 14-second period, and a gentle breeze. The energy is moderate (572). It’s worth a look if you missed Saturday.
From Monday the 10th onwards, the wind stays cross-off, and the swell drops a bit, but the period gets *very long*. On Monday afternoon, we see a 3ft SW swell with an 18-second period, pushing moderate to strong energy (1015). That’s a proper groundswell. At a reef like Tongo, that long period is a gift—it’ll wrap in nicely and offer some real shape, but be ready for longer lulls between sets.
The middle of the week, from Tuesday the 11th through to Wednesday the 12th, gets a bit messy. The wind cranks up to 15-18 mph, and we see a short-period, 5ft SSE windswell with a pathetic 7-8 second period. The energy is moderate (854) but the quality is poor. This is more of a washing machine.
Things pick back up on Thursday, August 13th. The morning sees a 4ft SW swell, 18-second period, and moderate energy (1074). The afternoon jumps to 4ft SW, still 18 seconds, and strong energy (1343). The wind is still cross-off, but the swell quality is there. Friday, August 14th looks even better on paper: 5ft SW swell, 16-second period, and strong energy (1445 and 1346). The wind is a gentle breeze. This is the standout for the second week. If you can only pick one day, Friday the 14th is the call. The size is solid for an advanced reef, the period is long, and the energy is high. It’s a proper swell.
After that, the swell slowly backs off into the 3ft to 4ft range through the rest of the week, with the period settling around 14 seconds. The wind stays cross-off, so the conditions are rideable but not perfect. The combined energy drops back to moderate (722-986).
Into the third week, from the 19th onward, the swell drops to 2ft to 3ft, and the period shortens up to 8-9 seconds. The energy tails off to weak-moderate (323-442). The wind is still cross-off. It’s small and not really worth getting excited about.
The best of the window is clearly Saturday, August 8th morning for the cleanest conditions, and Friday, August 14th for the biggest, most powerful swell. Keep in mind, Tongo Reef is a proper advanced break, and with a 5ft swell and strong energy, it’s not for the faint-hearted. The long-period swells are perfect for this reef, so the shape should be excellent.
Stay safe out there.
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.
