The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a 16-day window for Tongo Reef, and honestly, it’s a slow burn for a while before things get real. The early part of the period is just not worth paddling out for – the swell is tiny, a mere 2ft to 3ft, with combined energy that barely gets into the moderate range (264 to 640). Winds are cross-off from the SSE or S, but it’s not doing much for tiny, weak waves. The only real standout in this whole window is right at the end, and that’s a long-range call.
The water is notably warm – about 8°F above average at 78°F, which is very unusual for this time of year. You won’t need more than a spring suit.
From the 23rd of August through to the end of the month, it’s mostly marginal. There’s a little lift on the 27th with a 3ft swell from the SW and energy hitting 887, but the wind is still cross-off, not ideal. The 28th of August finally shows some muscle: a 6ft to 6ft SW groundswell with a 16-second period, energy pumping at 1546 to 1733. This is proper swell, but it’s still cross-off wind, not the clean offshore we want. Still, for experienced surfers, Friday the 28th offers excellent conditions. Best of the first week? That Friday morning.
A big gap follows with nothing special, then the real standout arrives on the 3rd and 4th of September. Swell jumps to 7ft from the SW, period 16 to 17 seconds, and the combined energy is massive – over 2700. That’s very strong wave energy. The wind is a gentle breeze from the SSE, which is cross-off but light enough to keep it reasonably clean. This is expert-only territory at that size. The 4th of September morning is the pick: 7ft SW swell, excellent conditions for experienced surfers. If you’re advanced and can handle a heavy reef break, that’s your session. Just be aware this is long-range, so keep an eye on it.
Tongo Reef is a reef break that’s fairly consistent, exposed to the swell, and works best when it’s coming from the S. It can get crowded sometimes, so you might have to share. The long periods (15 to 20 seconds) mean the waves will have plenty of energy and shape, but at a reef, that’s a beautiful thing. If you’re not comfortable in the big stuff, skip the 3rd and 4th of September.
So, bottom line: the first week is a write-off until Friday the 28th, then a few days of mediocrity, then a real heavy-hitter window at the start of September. Hold out for the 4th.
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.
