The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cooking for the Sanur - Grand Hyatt reef break over the next couple of weeks. I’ve got to be straight with you – the outlook is a bit of a tough one. The waves are there, but the conditions are fighting us every step of the way.
The main issue is the wind. For the entire forecast period, we’re looking at a persistent cross-onshore breeze from the southeast, and often it’s blowing straight onshore. That’s going to put a chop on the face and make things feel messy. The swell is coming from the SSW, which isn’t a bad direction for this spot, but it’s not the optimum south swell this reef loves. The water temp is sitting at 80°, which is pretty much bang on average for this time of year, so no wetsuit needed.
Looking at the first week, starting Tuesday the 8th of September, we’ve got a solid groundswell running. The swell is about 5 ft, with a long period of 18 to 19 seconds, which means proper, powerful lines. But, and it’s a big but, the wind is a cross-onshore 9 to 12 mph, and the wave comment just says “marginal surf forecast.” It’s going to be a choppy, bumpy ride. A bit of a heartbreaker, really.
Wednesday the 9th sees the swell bump up to 8 ft, still with that long 16-second period. The wind is still a cross-onshore, though a little lighter. The size is getting into that expert-only territory, and with the chop, it’s not going to be a pretty picture. It’s powerful, but it’s not clean.
The rest of that first week and into the second week is more of the same. The swell hangs around in the 4 ft to 7 ft range, and the wind just won’t let up. It stays onshore or cross-onshore, and the “poor surf conditions” and “marginal” comments are a constant theme. The crowds are “often” around here, so you’ll have company in the lineup, but honestly, I’d be looking for shelter elsewhere.
Now, there is a glimmer of hope right at the end of the forecast. Towards the 22nd and 23rd of September, we see the swell size pick up again, hitting 7 ft to 7 ft, with a period of 16 to 17 seconds. The wind is still not perfect, but it looks a little lighter. If you’re an expert surfer who can handle a bit of chop and loves a powerful, long-period wave, that might be the best window right at the end. But we’re talking about a week and a half away, so take that with a grain of salt.
The standout? Honestly, there isn’t a true standout. This is a reef break that needs clean conditions to shine, and it’s not getting them. The best on offer is probably the morning of the 22nd of September, with that 7 ft SSW swell at 17 seconds and a lighter onshore breeze. It’s powerful, but it’s not the clean, glassy day we’d all be hoping for. For beginners, the swell is consistently over 5 ft, and with the chop, it’s a no-go. For the experts, it’s a case of being ready for a bumpy, powerful session.
Alright, that’s the long and short of it. Not a classic run for Sanur.
Rusty.
