Sanur - Grand Hyatt Surf Forecast and Surf Report

Right, listen up. The next couple of weeks at Sanur – Grand Hyatt (Indonesia) ain’t shaping up to be anything special, to be honest. The water temp is about what you’d expect for this time of year, nothing wild.

The whole deal is a long-period SSW groundswell that’s just relentless. The periods are huge, often over 15 seconds, and the combined energy is strong – we’re talking numbers like 1126 up to 3520 in the afternoons, so there’s a ton of power. But the wind is a problem: it’s almost always onshore or cross-onshore from the ESE or SE at 9 to 12 mph. That’s messing up the surface, and the wave reports are all “poor” or “marginal.” The swell is coming from the SSW, which is off from the optimum S direction, so it’s not lining up right.

The first time you might even think about it is Thursday morning, 27th August. The swell is 4ft from the SSW with a 16-second period, combined energy of 1126, but the wind is onshore from the ESE at 9 mph. It’s “poor surf conditions,” so forget it. The afternoon has a 3ft swell with a 20-second period – that’s super long – and energy at 1646, but it’s “marginal” with a cross-onshore breeze. Not worth the paddle.

The next few days are a grind. Friday, 28th August, jumps up to 8ft in the morning and 7ft in the afternoon from the SSW, with periods around 16 seconds. The energy is high (3039 and 2504), but the wind is still cross-onshore, keeping it “marginal.” That’s getting into the “too big for beginners” zone, and the wind is making it messy.

Saturday, 29th August, is the best of a rough bunch. The morning has a 6ft SSW swell, 15-second period, and light cross-onshore wind from the SSE at 6 mph. The combined energy is 1382, and it’s the only day with a score of 3 out of 10. The report says “marginal” but with “light cross-onshore with small wind ripples.” It’s not glassy, but it’s the cleanest you’ll get. The afternoon drops to 6ft and a shorter 14-second period, with the wind picking up to 9 mph – back to “gentle cross-onshore and fairly choppy.”

After that, there’s a long dry spell. From Sunday, 30th August, right through to the afternoon of Friday, 4th September, it’s all “poor surf conditions” with scores of 0. The swell hangs around 4ft to 5ft, but the wind is onshore at 9 to 12 mph, and the energy is moderate (586 to 1210). No sessions worth talking about.

There’s a little flicker on the morning of Sunday, 6th September, with a 7ft SSW swell, 16-second period, and combined energy of 1988. The wind is onshore, so it’s “marginal” with a score of 1. The afternoon is the same size with a cross-onshore breeze – still “marginal.” That pattern repeats: Monday, 7th September (6ft, 14-15 seconds), Tuesday, 8th September (7ft morning, 7ft afternoon, 14 seconds), and Wednesday, 9th September (8ft morning, 8ft afternoon, 16 seconds). The energy is strong (1136 to 3520), but the wind is always on or cross-onshore, and the ratings are all 1 or 2. The 8ft on Wednesday afternoon is only for experts, and with a moderate cross-onshore wind making it choppy, it’s a tough slog.

The last few days, Thursday, 10th September, and Friday, 11th September, are more of the same: 8ft to 6ft, SSW swell, long periods, onshore wind, “marginal” calls. No standout.

If you’re a local, you know the score. The best shot is Saturday morning, 29th August – the light wind makes it the most surfable, but it’s still a cross-onshore breeze. The long-period swell works better on a reef, and this is a reef, but the direction isn’t ideal. With the constant onshore wind, this setup is more interesting for kite surfing than paddle surfing on most days.
