The Lowdown
Alright, this is Rusty, lookin' at the waves for Shipwrecks on Nusa Lembongan. This is a reef break for the advanced crew, so don't even think about paddling out if you're not ready.
The water temp is about what you'd expect for this time of year, nothing crazy.
The swell starts pumping on Saturday, 22 August. You've got a clean 7ft SSW groundswell with a 16-second period, and a 20 km/h offshore breeze from the ESE. The energy is heavy (1958). This is a top-tier morning: clean, powerful, and lined up.
Sunday, 23 August, morning is just as good. A 6ft SSW swell, 15 seconds, with a lighter 15 km/h offshore wind. The energy is still strong (1699). Another very good session.
The middle of the week drops off a little. Tuesday, 25 August, morning has a 5ft SSW swell with offshore winds, 20 km/h. It's clean, but the energy is moderate (910). Still worth a paddle.
But the real standout is Friday, 28 August, morning. A 8ft SSW groundswell with a 16-second period, and offshore winds from the SE at 20 km/h. The energy is massive (2686). This is excellent surf, but it's for experts only. That's your best wave.
Going into the next week, Tuesday, 1 September, morning is another one to circle. A 5ft SW groundswell with a very long 19-second period, and solid offshore winds at 25 km/h. The energy is huge (2413). The long period might make it a bit walled at a beach break, but on a reef like Shipwrecks, it'll be a dream.
Wednesday, 2 September, morning keeps the run going with a 6ft SW swell at 17 seconds and a gentle 15 km/h offshore breeze. Clean and powerful.
There's no dead period here; the surf just keeps coming. Mornings are your best bet for the cleanest offshore conditions. The afternoons lean cross-offshore, which is still clean but not as perfect.
When the swell is over 8ft, it's strictly for experts. The smaller days at 5ft and under are more manageable for those who know what they're doing. The crowds here can show up sometimes, so be ready to share the peak.
Bottom line: Friday, 28 August morning is the one to plan for, and keep an eye on Tuesday, 1 September morning. Those are the real standouts.
Rusty.
