The Lowdown
Alright, this is Rusty comin' to ya from the shores of Bali, and we’re looking at a tricky stretch ahead at Sanur – Grand Hyatt. I’ve got the lowdown for the next two weeks, but I gotta be straight with ya: this isn’t gonna be a classic run. There’s some serious size coming in, but the wind is gonna be the main character here, and not in a good way.
We’re starting on Thursday the 13th of August with a pulse of solid swell already in the water. We’re talking a raw 8ft of S groundswell, with a long 17-second period. That means serious energy down there – the wave energy is a whopping 3426, so it’s got some punch. But the problem is the onshore wind. It’s howling out of the SE at 13 mph, putting a cap on things. The water temp is about average for this time of year, but with that wind, you won’t be thinking about the temperature, you’ll be thinking about the chop. By Thursday afternoon, the wind stays onshore and the conditions are just plain poor. This place is a reef break, so with that size and wind, it’s gonna be a washing machine for experts only, and even then, it’s not looking fun.
Moving into Friday the 14th, the swell drops a little to 7ft from the SSW, still with a lengthy 16-second period. The morning wind is still onshore from the ESE at 13 mph. The afternoon eases slightly to a 9 mph cross-onshore, which gives us a “gentle cross-onshore and fairly choppy” feel. Still not clean. The energy is still in the moderate-to-strong range at 2514. This pattern pretty much locks in for the weekend (Saturday 15th and Sunday 16th). The swell holds around 7ft to 7ft from the SSW, periods in the 15 to 17-second range, and the wind stays cross-onshore or onshore. It’s a grinding, choppy mess, marginal at best. The energy is always high, but the quality just isn’t there for clean paddle surfing.
By Monday the 17th, the swell starts to drop back to 5ft, but the wind is still onshore, and the conditions are described as “poor.” Honestly, the first week is a write-off for any sort of decent surf. There’s swell, but the onshore flow kills it.
We get a bit of a tease mid-week. On Tuesday the 18th, we see a spike in energy back up to 2068 with a 6ft SSW swell, 16-second period, and the wind stays onshore. It’s still marginal. Wednesday the 19th sees the swell jump back up to 8ft with a very long 18-second period. The energy is cranking again at 3347, but again, onshore wind kills the vibe. This pattern – big swell, bad wind – is a recurring theme.
Now, for the more promising part, but it’s a long way out so take it with a pinch of salt. As we head into the second week, from about the 24th of August onward, the wind looks like it might actually ease off. On Monday the 24th, we’ve got a 5ft SSW groundswell with an 18-second period and the wind is down to a light 6 mph from the ESE. That’s as close to glassy as we’re going to get in this forecast, and the energy is still strong at 2364. That’s the one to circle on your calendar. It’s still a long-period swell, which can be a bit straight at a beach break, but at Sanur’s reef, it should set up some nice lines if that wind stays light.
Tuesday the 25th holds a similar story: 6ft SSW swell, 16-second period, and light ESE winds at 9 mph. The energy is still there. The wind direction is still onshore, but the lighter speeds will mean much better conditions. This is the best-looking window we’ve got. The rest of the second week is a mixed bag of moderate onshore winds and solid swell, so keep an eye on that window from the 24th.
Overall, this is not a classic forecast for Sanur – Grand Hyatt. The first week is blown out. The second week offers a glimmer of hope, but it's a long-range gamble. If you’re a hardcore local, you might get a session in on the 24th or 25th. For anyone else, you might be better off checking the forecast again in a few days. This spot is a reef break, it’s inconsistent, and it gets crowded often, but when it’s clean, it’s worth the wait.
Stay stoked, but stay patient.
