The Lowdown
Alright, Rusty here, giving the lowdown on Tongo Reef for the next couple weeks.
Right now the ocean is pumping in some southerly groundswell, and the water is way warmer than normal – a full 8°F above average, so leave the thick wetsuit at home. The whole stretch is seeing cross-off breezes from the SSE and S, keeping the surface pretty clean for this exposed reef.
The action starts Wednesday afternoon, September 2nd, with a small 3ft SW swell on a very long 18-second period. It’s tiny, but the power from that long period will make it wrap nicely over the reef for the advanced crew. By Thursday the 3rd, we’re into the prime window: 5ft to 6ft SW swell, still pumping on 17 seconds. The wave energy is strong, pushing well into the thousands. The wind stays clean and cross-off all day, so Thursday morning and afternoon are the true standouts. This is heavy reef surf – too big for beginners.
Friday the 4th holds similar size at 6ft, and the wind is still good. Saturday the 5th eases a bit to 5ft and 5ft. The wind remains your friend.
After that, the swell tapers through the first week, dropping below 4ft by Sunday the 6th. Monday afternoon the 7th sneaks in a small 3ft SW swell with a 16-second period and very clean conditions – a nice, quiet session on the reef.
The second week from September 9th has a few pulses. Wednesday the 9th sees a bump back up to 5ft SW swell on 17 seconds, but the winds stay cross-off. Not as flawless as the first week but still rideable. By the 15th, Tuesday afternoon gets a cross wind instead of cross-off, so quality drops.
The best of the second week looks like Wednesday afternoon, September 16th, with 4ft SW swell, 14-second period, light breeze, and very good conditions noted. A promising little window.
So the no-brainer standout is Thursday September 3rd and Friday September 4th – solid 5ft to 6ft SW groundswell, long periods, strong energy, and clean cross-off winds. Tongo Reef will be cooking. Crowds are possible, so beat the pack.
This is Rusty, signing off.

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.
