Sanur - Grand Hyatt Surf Forecast and Surf Report

Alright folks, Rusty here. Gotta be straight with you – this 16-day stretch for Sanur is a tough one. We’re looking at a long, drawn-out run of marginal conditions with no real standout sessions. The surf is there, but it's constantly battling onshore winds and questionable tide windows. Think of it as a two-week period of "almost but not quite."

We kick off on Thursday, 10th September at Sanur - Grand Hyatt. There’s a solid 7ft SSW groundswell rolling in with a long 16-second period, packing some serious energy (2032). But the wind is howling straight onshore from the SE at 9 mph, chopping everything up. The water temp is a normal 80° for this time of year. This is a reef break, so that long-period swell might offer some shape, but with the wind ruining it, it's going to be a battle. It’s also an advanced wave, so don’t even think about it if you’re a learner – anything over 5ft is pushing it for beginners.

The pattern just repeats. Friday the 11th and Saturday the 12th are the same story: onshore SE winds and dropping swell (6ft down to 5ft). The energy stays high (1708 down to 1463) but the quality is trash. The crowds are likely here too, which just adds to the frustration.

We get a pulse on Sunday the 13th – a 6ft SSW swell with a very long 18-second period, energy spiking back up to 2103. But again, the SE wind is on it. It’s like watching a good wave get ruined. By Monday the 14th and Tuesday the 15th, the wind sometimes swings cross-onshore, which just makes it choppy.

There’s a slight window mid-week. Wednesday the 16th afternoon and Thursday the 17th see the wind ease slightly, and the 6ft swell keeps rolling. It’s still onshore or cross-onshore, but it’s less aggressive. This is the best you’re going to get in the first week – still messy, but at least surfable. The energy is moderate (1379 to 1288).

Then things get really quiet. From Friday the 18th to Tuesday the 22nd, the swell drops off a cliff. We’re looking at 3ft to 4ft stuff with energy values barely cracking 1000 (942 to 920). The wind is still lousy. Expect a 3-day gap of very marginal, weak surf. Not worth paddling out for.

A glimmer of hope arrives on Wednesday, 23rd September. A fresh SSW groundswell of 6ft with a 17-second period hits, energy surging to 2310. It’s the strongest energy of the whole run. But again, the SE onshore wind is there in the morning. The afternoon tries to turn cross-onshore, but it’s still messy.

That energy keeps pumping into Thursday the 24th (2155) and builds again for Friday, 25th September. Friday morning looks promising on paper – 8ft SSW swell at 16 seconds, energy at 2821, and the wind is onshore but lighter. That’s a big, powerful swell. However, at 8ft, this is strictly for experts only, and with that onshore wind, it’s going to be a bumpy, powerful ride. It might be more interesting for kite surfing than paddle surfing if the wind holds.

Honestly, for the 16-day outlook, there are no true standouts. The best you can hope for is to pick a morning with the lightest onshore breeze and grab a few rugged, bumpy waves on the 23rd or 25th of September. But this is not a period to get excited about. The conditions just aren’t cooperating.

Rusty.
