The Lowdown
Alright folks, let’s talk Tandjung-Lefts. For the next 16 days, it’s the only game in town, so we’re stuck with what we get – and what we get is mostly choppy and messy.
Water temp is about 80°F – nothing weird there, right where it should be for late summer. But the wind is a problem: almost all day, every day, it’s coming from the ESE or SE at 10 to 16 mph, sitting cross-onshore. That means bumpy, ripply surf. Not clean.
We start on Tuesday 25th August. Swell is 5 ft from the SSW, period 15 seconds, and the energy is strong at (1155) – but the comment is “poor surf conditions.” That 16-second period later in the day is groundswell, which would normally be dreamy on a reef, but the cross-onshore breeze just trashes it.
The best bet in the first week is Thursday 28th August morning: swell hits 8 ft from the SSW, 16-second period, energy blasting at (3139). That’s expert territory. Wind is still cross-on from the SE at 9 mph, so it won’t be glassy, but there’s so much power you’ll get some proper slabs. The afternoon eases to 8 ft, but wind turns cross-shore from the SSE at 9 mph – the best wind of the whole run, with only slight cross-chop. If you can handle the size, that’s your session.
From 30th August through the start of September, it’s back to poor conditions with moderate breezes and chop. Crowds here are “sometimes” – on the rare clean windows, expect a few locals out.
Second week picks up a bit on Sunday 6th September: 6 ft from the SSW, 15 seconds, energy (2211), still cross-on but with a gentle breeze so the surface isn’t a total mess. The real standout in week two is Monday 7th September afternoon: 7 ft swell, cross-shore wind from the SSE at 9 mph, energy (1822), and that “gentle cross-shore with slight cross-chop” note. That’s as good as it gets – decent size, cleaner, and the reef will give you some nice lefts.
After that, it fades again into marginal and poor conditions through 9th September. Bottom line: this is a tricky run of wind-blown conditions. If you’re a solid surfer, aim for the 28th August morning for raw power, or the 7th September afternoon for the cleanest ride. Beginners should sit this one out.
Keep an eye on it – forecasts change.
