The Lowdown
Alright, let’s get this in feet and miles per hour for you.
We’re looking at Tandjung-Lefts, a classic reef break that’s going to get some serious juice over the next couple of weeks. The water temp is about average for the season, so you’re good with a standard summer suit. The first week, though, is a total write-off. The wind is hammering from the ESE at 9 to 21 mph, blowing cross-on, and it’s turning the ocean into a mess. The swell is okay, but it’s short-period and choppy.
From Sunday, July 26th, through the week, the surf is poor. The swell is from the SE, with a period of 8 to 9 seconds, and the combined energy is moderate, between 700 and 950 (moderate). The conditions are just lumpy and cross-onshore. The best of a bad bunch is the afternoon of Friday, July 31st, when the wind drops to a gentle 9 mph, and the swell swings to the SSW with a period of 17 seconds. The energy is strong (1184), and the surf is *marginal*, but it’s still fairly choppy. The crowds at Tandjung-Lefts can be a thing sometimes, but with conditions this average, it might be quiet.
The weekend of August 1st and 2nd is a bit better. The swell is still from the SSW, but the period is getting long, 16 to 18 seconds, which is proper groundswell. Wave heights are in the 4 ft to 6 ft range, and the combined energy is strong, hitting 1416 to 1702 (strong). The wind is still cross-on, but it’s a gentle breeze, so the surf is only “fairly choppy” rather than a total mess. These are the best of the first week, but it’s not a standout. It’s a “marginal” call because of the tide and wind.
The real deal, and the only standout, is the period from August 8th to 10th. This is a week away, so keep it in the back of your mind. On Saturday, August 8th, the swell jumps to 7 ft from the SSW with a period of 17 seconds. The energy is very strong (2934). The wind is still cross-on, so it’s not perfect, but the size and power are there. The morning of Sunday, August 9th, it gets even bigger, hitting 10 ft from the SSW with a period of 17 seconds, and the energy is massive (5574). That’s a big, powerful groundswell. For a reef break, that long period (over 15 seconds) is a blessing, as the reef will shape it up nicely. But 10 ft is big, and with the cross-on wind, it’s going to be a challenging, expert-only session. The afternoon of the 9th and the morning of the 10th see the swell easing back to 8 ft to 10 ft, but still with very strong energy (4535 to 5527). The wind is still cross-on, so it’s not the cleanest, but the sheer size and power are the highlight. If you’re an advanced surfer, this is the window.
So, the first week is a bust. The second week of August has some real size and power, but it’s a long-range prospect and the wind is still a problem. The standout is the morning of Sunday, August 9th, for the biggest, most powerful swell of the run, but only for the experts.

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.
