The Lowdown
Right, let’s have a squiz at what’s going down, crew. We’re talking about Tandjung-Lefts. It’s a consistent, advanced-level reef break, taking south swells. The water temp is about average for this time of year, nothing to note there.
A bit of a slow grind at the start. Today and tomorrow the wind is cross-onshore and choppy, with surf around 6ft from the SSW, but the conditions are just rubbish. Not worth getting wet. The combined energy is strong (2009), but that doesn’t do much when the wind’s all over the shop.
By the 3rd and 4th, it’s still poor, with energy dropping into moderate levels. Gotta be patient. Saturday the 5th shows a flicker – still marginal, but the swell lifts back to 6ft–6ft (SSW) and the wind backs off to a gentle breeze. That’s the first chance.
The best stretch runs from Monday the 7th through Wednesday the 9th. The swell sits around 7ft to 8ft from the SSW, period 14–16 seconds – that’s a real groundswell with proper shape for a reef. The wind finally goes cross-shore on the 8th and the morning of the 9th with light breezes, so the surface will be clean. That’s the standout. Energy numbers are sky-high: 2612, 2910, 3227 – that’s strong, meaty swell. But at 8ft, that’s experts-only; keep the beginners on the beach.
After that, the second week gets messy again with more cross-onshore wind and moderate chop. The 15th tidies up a bit with cleaner winds and swell around 7ft, but it doesn’t have the same punch as that early-week window.
So if you’re gonna pick, go Tuesday the 8th and Wednesday the 9th. That’s your best shot – proper reef waves, clean faces, and plenty of power. Expect a crowd, but it’ll be worth fighting for a wave.

A general guide to surfing at Tandjung-Lefts can be found by selecting the local surf guide option on the grey menu.

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 Tandjung-Lefts 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.
