The Lowdown
Alright, folks, Rusty here again. Let’s talk about Tandjung-Lefts, a proper advanced reef break that needs a south swell to line up. The water’s about 81°F, which is just about normal for the season—nothing unusual there.
I’m not gonna sugarcoat it: the next 16 days are a total bust. The first surf window opens on Saturday the 18th, but every single session from then until the 2nd of August is rated “poor surf conditions.” There’s no standout, no hidden gem. The best you can say is that some days have more size, but it’s always blown out.
Let’s walk through it. Saturday the 18th and Sunday the 19th: the swell is 4ft to 4ft from the SSW, with a period of 13 to 15 seconds. That’s okay groundswell, but the wind is 16 mph from the ESE, cross-on and choppy. Energy is moderate, around 700 to 820. Not worth suiting up.
Monday the 20th brings a bump: 6ft to 7ft from the SSW, period 16 to 17 seconds, and energy over 2000 (strong). But the wind stays cross-on, 16 mph, and the surf is still poor. This pattern just repeats. Tuesday the 21st has 5ft to 6ft, Wednesday the 22nd drops to 3ft to 4ft, and Thursday the 23rd fades to 3ft. All cross-on, all choppy.
The morning of Saturday the 25th might catch your eye: 4ft from the SSW, 15-second period, wind from the ESE at 16 mph, but it’s “on”shore, not cross-on. Energy is 1166 (moderate). Still, the forecaster says “poor surf conditions,” so that’s a pass.
The end of the month and start of August see some solid size. The 28th of July has 5ft to 6ft from the SSW, period 17 to 18 seconds, energy over 3000 (strong). But the wind is cross-on, 16 to 19 mph, and it’s lumpy. The 1st of August hits 8ft from the SE, period 10 seconds, energy 2553—that’s a heavy wave, but with 19 mph cross-on wind, it’s only for the brave and the foolish.
Bottom line: this whole 16-day stretch is a wipeout. Tandjung-Lefts needs that clean south swell and offshore wind to shine, but we’re stuck with a stubborn cross-on breeze from the east and southeast. The reef’s there, the swell’s there at times, but the wind kills it. If you’re into kiting, maybe you’ll get a session, but for regular surfing, I’d wait for the next forecast. Things can turn around, but right now, it’s a no-go.
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. 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.
