Kuta Beach Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ll be straight with you – this outlook for Kuta Beach is a mixed bag with one absolute standout session that’s worth circling on the calendar. We’ve got a solid run of swell, but the wind is mostly cross-offshore, which is okay, but it's not the classic glassy perfection we all dream of. The water temp is sitting right on 80°, which is bang on average for this time of year, so no surprises there.

The real story starts on Saturday, 8 August, with a clean 8 ft swell from the SSW, but it’s got that “marginal” feel – likely a tide issue or just not quite lining up. That theme carries through Sunday, 9 August, with 7 ft swell and a moderate breeze. It’s surfable, but nothing to get the heart racing.

Then we hit Monday, 10 August. The morning is still a bit average with 6 ft, but the afternoon is where it all changes. That session is the standout. The swell jumps to 10 ft from the SSW, with a period of 18 seconds – that’s proper groundswell, full of energy and shape. The combined energy is a massive 4753, which is strong. The wind is a clean cross-offshore, and the notes say the tide is favourable. But here’s the thing: at 10 ft, this is expert territory. If you’re not comfortable in big, powerful surf, sit this one out. For the experienced crew, this is the best on offer – the swell direction matches the optimum SW, and the quality will be there. Crowds are listed as “always” at Kuta, so expect it to be packed.

Tuesday, 11 August, is another big day with 10 ft swell, but it’s a repeat of the same theme – only for experts. The energy stays high (4325 to 5717), but the wind stays cross-off. It’s not a beginner’s day.

From Wednesday, 12 August, through to Saturday, 15 August, the swell drops back into the 5 ft to 8 ft range, but the reports keep saying “marginal.” The energy is still moderate, but it’s like the swell and tide aren’t clicking. The Saturday afternoon on 15 August does show a solid 7 ft, 17-second SSW swell with a gentle breeze, and the notes say “excellent surf conditions for experienced surfers” – a solid option for the intermediates who can handle a bit of size.

The second week, from 17 August onwards, is a slower taper. Monday 17 August has 5 ft to 5 ft swell, which is more manageable for the average surfer, but the energy is dropping (around 900). The 21-second period on Tuesday 18 August is very long period, which means long, clean lines at Kuta, but it’s a beach break, so those long-period swells can be a bit straight. The energy is moderate (1908 to 2927), so there’s still some push. The wind stays cross-offshore, keeping it clean.

The end of the run, around 20 to 23 August, sees another pulse of 8 ft to 10 ft, but the wind starts picking up to 15 to 19 mph. That’s a fresh breeze, and it’s going to chop things up. The Thursday 20 August afternoon session has the 10 ft swell with favourable tide and wind, but again, it’s big. For the average punter, it’s a pass.

To sum it up: the absolute best session is Monday 10 August afternoon. That’s the one. If you’re a confident surfer, that’s your window. The rest of the period is a lot of “almost” sessions with either size or wind holding it back. If you’re a beginner, give the first week a miss and look at the 17 August session for smaller, cleaner waves. For the kite surfers, there’s plenty of wind and swell, so it’s worth a look.

Rusty.
