The Lowdown
Alright, let me tell you how things are shaping up here. The window starts on Monday the 14th of September at Tongo Reef. This is an advanced-level reef break, so it’s not one for beginners, and it’s fairly consistent. The water is 79°F, which is 10°F warmer than normal for this time of year—that’s way warmer than usual, so the water’s feeling like a bath.
We kick off Monday afternoon with a clean 4ft SW swell, period around 17 seconds—that’s a long-period groundswell, full of energy, nice and lined up on a reef. Winds are cross-off from the SSE at 12 mph, so it’ll be a bit textured but still clean. The combined energy is moderate at 993, so you’ll feel the push.
Tuesday morning is the standout early in the period. We’ve got a 4ft SW swell, period 16 seconds, clean with a gentle cross-off breeze at 9 mph. This is the best on offer in the first few days—an expected very good surf session. It’s only about 4ft, so it’s manageable for a strong intermediate, but with a reef and long period, the sets will be meaty and spaced out, making the paddle out easier. The energy is 905, still moderate but solid.
Through the rest of that week and into the next, the swell stays consistently around the 3ft to 3ft mark, all SW direction, with periods dropping from 17 seconds down to 12 seconds. The winds remain mostly cross-off from the SSE or S, 9-12 mph, so the surface stays clean. But the scores are lower, and the wave comments turn to marginal surf or questionable tide conditions. The energy drops gradually through the 700s, 600s, and into the 500s. It’s not poor, but it’s not cooking like that Tuesday session.
By Saturday the 19th, the wind picks up to 16 mph in the afternoon, and the energy dips to 749. Still ridable, but you’ll want to be on it earlier.
From Monday the 22nd of September, things take a turn. The winds shift cross-shore from the SSW at 9-12 mph, and the sea state gets a cross-chop. The surf quality drops off noticeably from the 22nd onward, with many records showing poor surf conditions. The swell holds around 3ft to 3ft, but the energy sinks into the 200s and 300s. This is when you’re better off doing something else.
There’s a gap of a few days with no solid recommendations. But then, on Sunday the 27th of September, the wind drops to a light breeze from the SSE at just 6 mph, and we get a 2ft SW swell with a 16-second period. The combined energy is 408—moderate—and the morning session is clean. That’s promising. It’s small but glassy, and with that period, the reef should produce a few fun ones. A nice way to end the stretch.
Monday the 28th morning also offers clean 2ft SW swell, 14-second period, gentle breeze from the SE. Another small but workable session if you’re patient.
Overall, the clear best session is Tuesday morning the 15th of September at Tongo Reef. Right-size, clean, and the longest swell period. After the 21st, it gets choppy and small, so don’t expect much until the final weekend, when things clean up again but stay tiny.

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.
