The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for Tandjung-Lefts.
Honestly, for the first week, it’s a bit of a write-off. The wind is a constant problem. Through the 17th, 18th, and 19th, we’ve got a moderate to fresh cross-onshore breeze making a mess of things. The swell is hanging around 4 ft to 4 ft from the SSW with a decent period, but that wind is just ruining the surface. It’s choppy and lumpy. Not worth paddling out for.
We get a bit of a pulse on the 20th, with the swell kicking up to 6 ft to 7 ft from the SSW. The energy jumps up to a strong 2223, but it’s still a moderate cross-onshore wind. The forecast just calls it “marginal.” It’s not clean, and for a reef like this, you want it glassy. That’s a pass.
From the 21st through the 24th, it’s the same old story. The swell drops back down, the wind stays onshore, and the surf quality is poor. There’s a shift on the 24th where the swell direction swings to the SSE and S, but the period drops to 8-9 seconds—short-period, windswell stuff. Combined with the onshore wind, it’s just messy.
The 25th, 26th, and 27th see the swell size getting bigger, pushing 7 ft to 7 ft from the SSE and SE. That’s getting into expert territory for sure, but the wind is still cross-onshore and at times a fresh breeze. The period is short, too. It’s going to be a lumpy, blown-out mess. Not for surfing.
Into the 28th and 29th, the wave state is still poor. The 29th morning shows a slight improvement with a gentle cross-onshore and a 4 ft SSW swell, but it’s only “marginal.” The water temperature is about average for this time of year, but honestly, the conditions aren’t good enough to enjoy it.
The 30th and 31st have a bit of promise on paper. The 31st morning has a very long period swell of 18 seconds from the SSW, with energy at 2155. That’s a proper groundswell, but the wind is onshore. The afternoon shows a 22-second period with 2666 energy, but again, it’s cross-onshore and choppy. That long period will make the reef line up, but the wind is the enemy.
The first of August has a big 6 ft SSW swell with a 20-second period and massive energy at 3157, but it’s a fresh cross-onshore wind. That’s a kite-surfing setup, not a paddle-surfing one.
So, the honest truth? There is no standout. There is no single day in this 16-day window where the wind is truly offshore and the swell is lined up. The best you can hope for is a “marginal” session on the 20th or maybe the 29th morning, but it’s going to be a fight. The constant cross-onshore wind is the killer here. This is a long stretch of poor surf for Tandjung-Lefts.

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.
