Sanur - Grand Hyatt Surf Forecast and Surf Report

Alright, Rusty here. Let's take a look at what's on the menu for the next couple of weeks at Sanur – Grand Hyatt.

Honestly, it's a tough stretch ahead. We've got a solid, consistent SSW groundswell running, with periods often hitting 15 to 18 seconds, which is proper long-period energy. The combined energy values are strong, regularly in the four-digit range (like 1170, 1421, 2026), so there's plenty of push. But the wind is the story here, and it's not a good one. For the entire 16-day window, we're looking at persistent onshore and cross-onshore breezes from the ESE and SE, mostly 9 to 16 mph. That's going to keep the surface messy and chopped up. The water temp is sitting at 80.6 °F, which is bang on average for this time of year, so no surprises there.

The first few days, from July 30th right through to the end of the first week of August, are basically a write-off for quality surf. The wave comment on the data is constantly "poor surf conditions" or "marginal surf forecast." The scores back that up—mostly zeros and ones. It's a real shame because there is decent swell, but the wind just ruins it. This break is a reef setup that needs clean conditions, and it's just not getting them.

There is a tiny flicker of hope on Saturday, August 1st, and Sunday, August 2nd. The swell bumps up a touch to 5.2 ft to 6.2 ft from the SSW, and the wind eases to a gentle breeze onshore. That might produce the best conditions of this whole grim period, with the afternoon of Saturday the 1st being the pick of a bad bunch. The period is 18 seconds, which is a deep groundswell, meaning long lines and plenty of power.

Honestly, the second week doesn't look much better. The wind stays locked in from the SE and ESE. The swell does build. We see 7.2 ft on Thursday, August 6th, and even 7.5 ft on Monday, August 10th. That's too big for beginners anyway. By Thursday, August 14th, the swell is up to a solid 9.8 ft with a 17-second period and combined energy hitting 5859. That's a serious amount of water moving. But again, with a cross-onshore wind, that size at this reef is going to be unrideable—a washing machine for all but the most experienced, and even they would be fighting the chop. The best days in this second week are probably the afternoons of Saturday, August 10th, and Tuesday, August 13th, when the wind drops to a gentle breeze. But "best" is relative; it's still cross-onshore.

So, the call is simple. There are no real standouts in this 16-day window for Sanur – Grand Hyatt. The consistent onshore wind kills it. It's a long wait with no real payoff. The only day worth even looking at is Saturday, August 1st, afternoon. The swell will be 5.2 ft from the SSW with an 18-second period, and the wind will be onshore but light. If you're desperate, that's your window. For the rest, save your energy. This stretch is a blank run for a reef that needs offshore or glassy conditions.
