Sanur - Grand Hyatt Surf Forecast and Surf Report

Alright mate, Rusty here. Let’s have a yarn about what’s coming up.

This outlook covers a decent 16-day stretch, but it’s a bit of a mixed bag. We’re looking at a solid run of swell from the SSW, but the wind is the main issue for most of it. There’s a lot of onshore and cross-onshore breeze, which is going to chop things up and keep the quality down.

Sanur - Grand Hyatt is the only spot on the menu, and it’s a tricky one. It’s an advanced reef break that’s pretty inconsistent, meaning it needs the right conditions to work. The water temp is sitting right on average at 79°, no surprises there.

Right from the get-go Tuesday morning (18th August), we’ve got a 4 ft SSW swell with a very long 16-second period. That’s a lot of energy (1868) but with an onshore ESE breeze at 9 mph, it’s looking messy. The tide or other factors are also questionable, so the overall score is low.

This pattern pretty much holds for the next week and a half. The swell stays solid, jumping up to 7 ft and 8 ft by Wednesday and Thursday (19th-20th August) with periods between 16 and 18 seconds. The energy is massive, hitting over 3500 at times, but the ESE and SE onshore winds at 9 to 12 mph are relentless. The notes keep saying “marginal” or “poor,” and for a spot that only breaks occasionally, we need it to be perfect. With this amount of wind, it’s just not that.

There’s a bit of a dip in swell by the 26th and 27th, dropping to 3 ft to 4 ft, and the energy falls off. Still, the wind is on it, so nothing changes.

Now, as we push into the second week, things get a little more interesting. On Sunday the 30th of August, the wind finally shifts. We get a light cross-shore breeze from the south at 6 mph. The swell is solid again at 6 ft from the SSW with a long 18-second period. The energy is strong (2633). This is the standout moment. While the conditions are still described as “marginal,” that light cross-shore wind is the cleanest we’ve seen in weeks. For an inconsistent reef like this, that’s a serious opportunity. It’s not a sure thing, but it’s the best chance for a proper session.

After that, the wind swings back onshore through Monday and Tuesday (31st August-1st September), with the swell holding at 7 ft to 8 ft. The energy is still very high, but the quality will be gone. Feeling like this spot needs a real clean-up to get its act together. Into the start of September, the swell hits 8 ft which is getting into expert-only territory, but again, the onshore wind will make it a battle.

Forget the rest of the forecast. Sunday morning, the 30th of August, is your best bet. Get there early for the cleanest windows.

Rusty.
