The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming up at Tongo Reef over the next couple weeks.
This run starts with a solid pulse that fades out quick, then there’s a big gap of flat days before something builds back. The first few days pack a punch but have some strings attached. The real standout is further out, in the second week – you’ll have to be patient.
Monday, 27 July kicks it off with a proper SW groundswell, 6ft, with a long period of 18 seconds. The combined energy of all swells directed here is a strong 2063. The water is a warm 79°, which is about 9° warmer than normal for this time of year – that’s very unusual. Wind is SSE at 15 mph, blowing cross-offshore, keeping the surface clean. This is advanced territory at that size, the reef will be working, but it’s not a beginner’s wave. Crowds are possible. The score isn’t top-tier, but the raw swell is there.
Tuesday, 28 July holds similar conditions – 5ft, 16-second period, cross-off SSE wind at 12 mph. The energy is still strong at 1303. The swell is easing, but it’s still clean.
From Wednesday, 29 July, the swell starts dropping – 5ft, then 4ft, and by Saturday, 1 August, it’s down to 2ft. The period also drops, and the combined energy falls into the weak range, below 500. The wind stays cross-off, but there’s just not enough swell to get excited about. This is a lull, a proper gap of several days with no real recommendation.
On Sunday, 2 August, a new swell tries to show up – 4ft, but from the SSE with a short period of just 7 seconds. The energy is only 367. That’s weak, short-period windswell, not the kind that makes Tongo Reef work. This continues through the middle of the week – 3 to 5 August – with heights around 4ft to 4ft, periods still short, and energy in the 300-400 range.
The real turnaround shows up on Friday, 7 August. This is the standout. The swell is 4ft from the SSW, with a period of 16 seconds – proper groundswell. The combined energy climbs to 934, which is moderate to strong. The wind turns offshore from the SE at 9 mph, giving you clean, glassy conditions. This is a very promising window, but it’s over a week away, so treat it as a hopeful call. The reef will handle that long-period swell well.
The weekend of 8-9 August sees the swell mix up. The SSW groundswell hangs around, but by Saturday afternoon it shifts to a shorter-period SSE swell at 5ft and 10 seconds. The wind stays cross-off, but the quality drops.
The following Monday, 10 August, we see the swell bump to 6ft, still SSE with a period of 9 seconds. Combined energy is 988. The wind is a gentle cross-off, but the short period means the swell will be a bit junky. Tuesday, 11 August, drops back to 5ft, still SSE and short period.
So, the best of the whole run is a toss-up between the opening pulse on 27 July, which is big and powerful but only for experienced surfers, and the cleaner, more promising window on 7 August with offshore winds and a better swell direction. If I’m picking one, I’d say the 7th is the pick – less size but better quality with that offshore wind and a solid groundswell. It’s a long way out, but it’s the one to keep an eye on.
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.
