The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s happening at Sanur - Grand Hyatt (Bali).
Right off the bat, I gotta be straight with you: this isn’t a week for glory. The reef is putting on a show, but it’s a tricky one. The swell is coming from the SSW, which is the opposite of what this break really wants—it needs that S direction to be at its best. So, most of the time, the quality is just not there. We’re looking at a long stretch of “marginal” or “poor” conditions, with the wind blowing onshore from the ESE or SE, messing with the surface.
The first real pulse of energy hits Thursday afternoon, August 20th. Swell is 7ft from the SSW, with a long period of 16 seconds, so there’s plenty of power in the water (combined energy of 2628). But the wind is onshore at 12 mph, which means chop. Not ideal. The water is 79°, which is pretty normal for this time of year.
Friday the 21st is more of the same: 6ft to 7ft of SSW swell, still onshore, still messy. The energy is strong (2253 to 2791), but the wind is a buzzkill.
Saturday and Sunday, August 22nd and 23rd, offer no real improvement. The swell drops a little, but the wind stays onshore or cross-onshore. The combined energy is still high (around 1900 to 2100), but the surface is choppy. It’s frustrating, because there’s push there, but it’s not clean.
Now, hold on. Keep your eyes on Friday, August 28th. This is the standout. The wind swings around to the south, going cross-shore at 6 to 9 mph. That’s a game-changer. The swell is 7ft to 8ft from the SSW, with a 16-second period, and the energy jumps from 3037 to 4659—that’s serious power. For an advanced surfer, this is the best window we’ve got. The wind is light, the conditions are cleaner, and the reef will be working. Still, since the swell is coming from the SSW, not the optimum S, it won’t be perfect. But it’s the best on offer.
After that, the swell backs off into the first few days of September. We’ve got 6ft to 7ft from the SSW, with onshore winds again. The energy is still moderate (around 1500 to 2000), but the wind kills the vibe. It’s not terrible, but it’s not great.
Honestly, for this break, with the swell direction wrong and onshore winds dominating, the setup looks more interesting for kite surfing than paddle surfing for most of this period. The only day I’d really paddle out is Friday, August 28th, and that’s for the advanced crew.
Rusty.
