The Lowdown
G’day, Rusty here. Let’s break down Tandjung-Lefts. It’s a tough outlook for the most part, with a big run of poor conditions before a solid finish.
We start on Friday 28 August with a 8ft SSW groundswell, a long 16-second period, and huge energy (3043). The wind is cross-on from the SE at 9 mph, so it’s choppy. That’s a lot of power, but it’s messy. For advanced surfers only at that size. Water temp is about average for the time of year.
Friday afternoon is a touch better, with the swell easing to 7ft and the wind going cross-shore, but still a bit of chop. Marginal at best.
Saturday 29 August morning has the swell dropping to 6ft, with a light cross-shore wind. The energy is moderate (1382), and the period is a long 15 seconds. It’s a little cleaner, but still not great. The afternoon goes downhill.
From Sunday 30 August through Saturday 5 September, it’s a long, poor stretch. Swell hangs around between 4ft and 6ft, but the wind stays cross-on and moderate, making everything choppy. The energy drops off, and the conditions are poor for days. Nothing worth paddling out for.
Sunday 6 September and Monday 7 September are more of the same: moderate swell but cross-on wind. Tuesday 8 September morning has the lightest wind of the run at 6 mph, but it’s still cross-on, so only a little ripple on the surface.
The real standout comes at the end. Thursday 10 September afternoon shows a 6ft SSW swell with a very long 18-second period and strong energy (2097). Still cross-on, but the period gives it some punch.
But the best is Friday 11 and Saturday 12 September. Friday morning: 8ft SSW groundswell, 16-second period, huge energy (2950), and wind at 9 mph cross-on. Saturday 12 September morning tops it all: 8ft SSW, 18-second period, and a massive 4604 combined energy. That’s the biggest and most powerful swell of the entire forecast. The wind is lighter (9 mph SE), still cross-on, but for the advanced crew, that is the session to aim for. That kind of long-period groundswell really works on a reef like this. The water temp is average, so no surprises there.
For beginners, that 8ft is expert-only. The crowd at Tandjung-Lefts can be busy sometimes, especially on the good days.
In short, don’t bother for the first week and a half. The real highlight is Saturday 12 September morning. That’s the one to mark on your calendar. Everything else is poor to marginal.
Rusty.
