The Lowdown
Righto, grab a coffee and pull up a chair. Rusty here. Gonna be a long 16 days for this stretch of coast, so let’s get into it.
Overall, the pattern is one big frustration. There’s a serious amount of swell coming through, but the wind is just cruel – it’s almost always tearing across the face from the east or southeast. The only break on the radar is Tandjung-Lefts, a heavy, advanced reef. The water temp is about average for the time of year, so nothing unusual there.
The first few days from Wednesday the 29th of July through to Friday the 1st of August are a write-off. Swell is building, but it’s all cross-on and choppy. The energy is moderate to strong, but the wind is a solid 16 mph messing it up. Not worth paddling out for.
There’s a slight tease on Sunday the 2nd of August. The swell is bumping up to 6 ft from the SSW, with a very long period of 16 seconds, and the combined energy kicks up. The wind drops to 9 mph from the ESE, but it’s still onshore. The surf is labelled “marginal” – you might get a couple, but it’s going to be a battle.
The best of a rough bunch looks like Sunday the 9th of August. The swell is a solid 8 ft from the SSW, and the period is a pumping 17 to 18 seconds – that’s groundswell with proper energy. The wind finally shifts to a gentle 9 mph from the SSE, going cross-shore. That’s the cleanest it’s going to get. This is for experts only, though – at 8 ft on a reef with a long period, it’s gonna be powerful and lined up. It’s a standout, but keep your expectations in check because it’s a week and a half away.
The days after that see the swell stay big (7 ft to 8 ft) but the wind swings back to cross-on. The energy is very strong but the quality isn’t there for a paddle session. For a beach break, this setup would be screaming for kites, but for a reef, it’s just frustrating.
Honestly, if you’re not an expert, there’s nothing here for you. If you are, keep your eye on Sunday the 9th of August. Could be a few gems.
Rusty.

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.
