Sanur - Grand Hyatt Surf Forecast and Surf Report

G’day, Rusty here. Let’s be straight with you: this stretch of coast isn't going to be throwing any world-class barrels your way over the next couple of weeks. We’ve got a long, drawn-out run of average to below-average conditions, with only a couple of short windows that might just get your heart rate up. The swell is coming from the SSW, but the local winds and the way this spot sits mean it’s going to take a bit of effort to find something clean.

The first bit of the window is a write-off. From Monday the 17th through to Thursday the 20th, we’ve got waves, sure, but the quality is just not there. The size is there - 5ft to 8ft - but it’s all that “poor surf conditions” kind of energy. The wind is on it from the SE/ESE, and even though it’s a “gentle breeze,” it’s enough to mess things up. The period is around 14 to 16 seconds, which is okay, but the wave comment just screams “don’t get too excited.” You’ll see the combined energy is weak early on (around 800), then builds to a moderate 1910 on Tuesday, up to a strong 3075 on Wednesday morning. But strength without form is just a mess. Honestly, for the first four days, I’d be looking for something else to do.

Now, here’s the thing. The real standout, the one to mark on your calendar if you can wait, is the middle of next week. On Wednesday the 19th into Thursday the 20th, we see the swell push up to 7ft to 8ft with a solid 17-18 second period. That’s proper groundswell energy coming through. The combined swell energy tops out at a strong 3561 on Wednesday afternoon and 3179 on Thursday morning. That’s the biggest, most powerful pulse of the whole run. The problem? The winds are still SE/ESE, which is offshore for this spot. And that’s a big deal. Offshore wind on a decent-sized, long-period SSW swell at a reef like Sanur - Grand Hyatt is the recipe for clean, lined-up sets. This is starting to look like the best bet for a proper surf. The size is in the 7ft to 8ft range, which is starting to get serious. It's not for beginners, but for the advanced crew, this is the window. Sure, the forecasts are a few days out, so it's not a guaranteed lock, but this is the most promising part of the outlook.

After Thursday the 20th, it starts to taper off. Friday the 21st through the weekend still has size - 5ft to 7ft – but the wind is still on it, and the quality drops back to that “marginal” or “poor” category. The period drops back to 15-16 seconds, so it loses that punch. The 23rd and 24th see the wind shift a bit to a cross-on direction, which will make things choppy, and by Monday the 25th we’re down to 5ft to 5ft and the energy is weak, around 991. It’s a slow fade.

The back half of the second week, from about the 25th through the 28th, is pretty lackluster. Swell drops to 4ft – 5ft, period is down to 13-14 seconds, and the energy is weak. Not much going on.

But hold on. Just when you think it's all over, there’s a little spike at the very end. Around Sunday the 30th and Monday the 31st of August, we see a new pulse of longer-period SW swell, 18 seconds, with energy picking up to a solid 1927. The size is 5ft to 6ft, and the wind eases off to a light breeze, though it is cross-on. It’s still a step up from the doldrums, and those longer-period waves will have some push to them. This is a chance for some fun, less challenging waves, but still far from perfect. This one is promising, but it's a long way out, so temper expectations.

So, to sum it up: the first few days are a bust. The real standout is Wednesday and Thursday of next week, the 19th and 20th, when we get size, power, and clean offshore wind at Sanur - Grand Hyatt. That’s your best shot. The end of the month has a second, smaller pulse that might be worth a look if the winds hold. Water temp is about normal for this time of year, around 79°, so it’s warm.

This spot is a reef, and on those bigger days it’s for advanced crew only. Crowds can be a problem here often, so the bigger, more powerful days might thin them out a bit. For the most part, expect a lot of average to poor surf. If we do get a storm in the next 16 days, things could change, but based on what I’m seeing, this is your plan.

Stay salty.

Rusty.
