Balangan Surf Forecast and Surf Report

G’day, I’m Rusty, and I’ve been looking at the charts for Bali’s Bukit Peninsula. We’ve got a proper run of south-west groundswell coming up for Balangan, and it’s looking like a solid winter window. The water temp’s about average for this time of year, so nothing unusual—just your normal tropical warmth.

The pattern starts Wednesday 5 August with a clean morning. Swell’s already pushing 6 ft from the SSW at a long 15 seconds, and with that ESE breeze blowing 25 km/h offshore, the reef is gonna be glassy. The combined energy is strong at 1468, and it’s a real gem for experienced surfers. If you’re a beginner, that 6 ft might be a bit much—stick to the inside.

Thursday 6 August sees the swell bump up to 7 ft, period stretching to 17 seconds. The morning offshore is fresh at 30 km/h, cleaning up the face. Energy’s climbing to 2460, and while the tide might play games, the afternoon looks even better. This is a standout for the first few days.

Friday 7 August is the pick of the early window. Swell hits 8 ft from the SSW, period at 17 seconds, and the wind stays offshore all day—20 to 25 km/h. The energy is massive at 3322 in the morning, peaking at 3605 in the afternoon. For a reef break like Balangan, that long period is perfect—it’ll wrap in cleanly. It’s expert territory now, so if you’re not solid, sit this one out.

Saturday 8 August holds similar size, 8 ft, with the same long period. The morning is another offshore clean-up, but the afternoon swings cross-off, so it’ll be a bit wonky. Still, consistency is high, and the energy sits at 2786.

Sunday 9 August brings rain showers in the morning, but the swell is still pumping at 7 ft. The wind is a fresh 30 km/h offshore, so expect some bumps. The afternoon clears up, and the energy is still strong at 1972.

Now, Monday 10 August—this is where it gets interesting. The morning has a 5 ft swell but with a ridiculous 20-second period, making it a very long-period groundswell. Energy is 3123. That’s a dream for Balangan’s reef—it’ll hold up and offer long, walling lines. The afternoon jumps to 10 ft with a 19-second period, energy hitting 5135. That’s massive, and while it’s marginal for tides, it’s a serious standout for experts.

Tuesday 11 August is the absolute peak. Morning swell is 10 ft at 17 seconds, energy 5128, with offshore winds. The afternoon drops to 8 ft but still with 16-second period. This is the best day of the whole run—big, clean, and powerful. If you’re an experienced surfer, this is your call.

The rest of the first week eases slightly but stays solid. Wednesday 12 August has 8 ft, Thursday 13 August 8 ft, and Friday 14 August 7 ft—all with offshore winds in the mornings. The energy stays in the 2000-3000 range, so it’s punchy but not insane.

Into the second week, Saturday 15 August and Sunday 16 August both have 7-7 ft swell with offshore winds, though the energy drops a bit. Monday 17 August sees a dip to 5 ft, but the period is still 14 seconds—still surfable.

Then Tuesday 18 August and Wednesday 19 August fire up again. Swell jumps back to 8-10 ft, period at 17 seconds, and the energy is back up to 4039 and 4852. The wind on Wednesday 19 August is light cross-off, which is fine, but the real standout is Thursday 20 August—morning has 8 ft swell, 16-second period, and a slight 5 km/h offshore breeze. That’s about as glassy as it gets. Energy is 3566.

Crowds at Balangan can be a problem—it’s a popular spot, and with this quality of swell, expect it to be busy. If you’re looking for a quieter session, it’s a trade-off, but the wave itself is worth it.

Overall, the best on offer is Tuesday 11 August and Thursday 20 August. The former is a full-on big swell day with offshore wind, the latter is a slightly smaller but glassy gem. For the rest, it’s a consistent run of quality groundswell—just pick your morning sessions for the cleanest conditions.
