The Lowdown
Alright everyone, Rusty here giving you the lowdown.
First thing, the water is 80°F, which is right on the money for this time of year.
Honestly, it’s a bit of a slow start. From Thursday the 3rd right through the weekend, the wind is blowing from the ESE and SE at 15 to 16 mph, cross-onshore, and it’s got the ocean all chopped up. There’s swell in the water, 3 to 6 feet from the SSW with a long period of 14 to 16 seconds, but that wind is just wrecking the surface. The wave energy is moderate to strong (values between 839 and 1572), but it’s not surfable. If you’ve got a kite, this might be more your scene.
Things start to look up a bit from Monday the 7th. The wind relaxes a little and turns cross-shore, blowing around 9 to 12 mph. The swell holds steady at 6 to 7 feet from the SSW, with a 14-second period. The wave energy is strong (1399 to 1873). Monday afternoon is the best of the early week, with a gentle cross-shore breeze and just a slight chop on the surface.
Now, Tuesday the 8th is the one to watch. The morning brings a 5-foot SSW swell with a very long period of 19 seconds, and the afternoon bumps up to 6 feet with an 18-second period. The wave energy is very strong (2569 and 2947). This is a proper groundswell. For a reef break like Tandjung-Lefts, that long period is a good thing, as it will wrap in nicely. The wind is a gentle cross-shore, so the waves will be clean. This is the standout window.
Wednesday the 9th is still solid, with 7 to 8 feet of SSW swell and a 16-second period, and the cross-shore wind sticks around. That’s big enough for experts only.
From Thursday the 10th onward, the wind goes back cross-onshore, and the quality drops. The swell stays around 5 to 6 feet, but the surface gets rough again. The second week, from the 12th of September, is basically a no-go. The wind stays onshore and the swell fades away. The 17th and 18th are poor with choppy, onshore winds.
So, the best surf is Monday afternoon through Wednesday the 9th. The absolute standout is Tuesday the 8th, with that very long period groundswell and the clean, gentle cross-shore wind. It’s a reef break, so expect nice, wrapping waves. But it’s sizeable, so only for the experienced.
Remember, crowds can be a thing here, so keep your eyes open.
Rusty, out.
