The Lowdown
G'day, Rusty here. Let's have a look at what's on offer at Tandjung-Lefts (Bali) over the next 16 days.
Alright, straight up, the next week and a half is a bit of a write-off for quality surf. The wind is stubbornly hanging in from the ESE to SE, blowing cross-onshore, which is keeping the surface messy and choppy. There's a solid SSW groundswell running through the first week, but the conditions just aren't letting it show its best. The water temperature is sitting at 79°, which is pretty much standard for this time of year.
The real standout window opens up on Wednesday, 2nd September. That morning, things finally come together. The wind swings light from the SSW, giving us a clean cross-offshore flow. The swell drops to 6 ft from the SSW, with a period of 16 seconds, and the combined energy is moderate at 1411. This is the one to circle. Tandjung-Lefts is a consistent reef setup, and with clean conditions, it'll be offering some proper, well-shaped waves. This is the pick of the forecast.
Leading up to that, Thursday, 27th August, shows a brief flicker of hope with a long period 19-second SSW swell and a light, cross-shore wind, but the swell is a bit undersized at 4 ft. The morning of 28th August has a bit more size, with 8 ft from the SSW, but the wind is already back to cross-onshore, chopping it up.
From the start of the forecast through to the end of the first week, it's pretty much a grind. The energy is strong, with readings mostly in the 2000-3000 range, but the constant cross-onshore wind means you're looking at a fight. The 8 ft swell on Thursday, 20th August carries a very strong energy of 3174, but with a cross-onshore wind, it's a real handful. This is more for the kites out there than paddle surfing.
Overall, the Tandjung-Lefts forecast is a tale of two halves. Be patient, sit out the choppy, wind-affected first week, and wait for that clean Wednesday morning on the 2nd of September. It's a long way off, but it's the one that's got the most promise.
Rusty.
