The Lowdown
Alright, Rusty here. Let’s check out what’s on the menu for Tongo Reef. It’s a slow start, but there are some gems in the second week if you’re willing to wait.
For the first several days, from Wednesday July 29th through to about August 5th, the swell is hanging between 2.3ft and 4.6ft, coming from the SW with a period of 12 to 14 seconds. The wind is cross-off from the SSE to S, blowing at 9 to 16 mph, keeping things clean. The combined energy is moderate, ranging from 280 to 801. Water temp is a warm 79.5° with a big anomaly of +5.4°, so it’s far warmer than usual for this time of year. But the surf quality is mostly marginal or poor, so it’s a bit of a flat patch with no real standouts.
Now, pay attention to Thursday August 6th. The morning brings a clean 3ft SSW swell with a very long period of 17 seconds, and the combined energy jumps to strong at 1027 (strong wave energy). Wind is a gentle cross-off from the SE at 9 mph, and conditions are excellent for experienced surfers. That long period groundswell will wrap into this exposed reef, giving it shape and power, though sets will be spaced out. This is advanced-only territory.
Friday August 7th keeps it going with a morning swell of 4.6ft from the SSW, period at 15 seconds, and energy still strong at 992 (strong wave energy). Gentle cross-off wind from the SSE keeps it clean. Another very good session.
Then circle Monday August 10th. The morning is glassy with a light offshore wind from the SE at 9 mph, and a 2.6ft SW groundswell with a very long period of 19 seconds. Energy is high at 935 (strong wave energy). This will be clean and lined up, perfect for a reef that likes swell from the S. Crowds can be a factor sometimes, so get out there early.
The rest of the second week fades back into smaller, marginal conditions with cross-off winds and moderate energy. Nothing to match those two standout mornings on the 6th and 10th.
My picks: the morning of Thursday August 6th and Monday August 10th. That’s where Tongo Reef will be cooking.

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.
