Balangan Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a solid run of swell aimed at Bali, and Balangan reef is the main act for the next 16 days. The water’s sitting at 80°F, which is bang on average for this time of year – nothing weird going on there.

The pattern kicks off Monday morning, September 7, with a solid 7ft SSW groundswell, period a meaty 14 seconds, and clean offshore ESE breeze at 12 mph. The combined energy is strong at 2003, so there’s plenty of push. This is excellent for experienced surfers – the reef will be handling the size well, but it’s not for beginners. That offshore wind holds through the afternoon, with the swell easing a touch to 7ft, still SSW, and the energy staying strong at 1604. Clean, powerful lines.

Tuesday morning, September 8, the swell holds at 7ft from the SSW, but the wind shifts to a cross-offshore SSE at 12 mph. The waves will still be clean, but the angle’s not as perfect. Energy jumps to 2916 – moderate to strong. The period drops to 13 seconds, still a solid swell. By afternoon, the period stretches out to 18 seconds – long-period groundswell – with 6ft SSW and energy at 3342. That long period can make the reef a bit more lined up, but it’s still good.

Wednesday morning, September 9, sees the swell bump up to 8ft from the SSW, period 16 seconds, energy cranking at 3182. Wind is cross-offshore SSE at 12 mph. This is getting big for the average punter – more in the expert zone. By afternoon, the breeze drops to 9 mph, still cross-offshore, and the swell eases to 8ft but with excellent conditions. Thursday, September 10, keeps the 7ft to 7ft range, SSW, periods around 15-16 seconds, and cross-offshore winds. Good energy, clean.

Friday, September 11, brings a switch to offshore ESE wind, 12 mph, with a 7ft SSW swell, period 16 seconds. Finally, that true offshore glassiness. Energy is 2022 – strong. The afternoon turns slightly more SW in direction, still 6ft, 16 seconds, still offshore. This is a standout window. Saturday, September 12, continues the offshore theme, with a 5ft SW swell in the morning, dropping to 5ft in the afternoon. Periods at 14 seconds. Clean, but easing.

Sunday, September 13, the wind picks up to 16 mph offshore SE in the morning, with a 6ft SW swell, 18-second period, energy 2579. That’s a long period groundswell – the reef will love it. Afternoon holds 7ft SW, 17 seconds, energy 2813. Offshore wind again. Another standout.

Monday, September 14, through to Wednesday, September 16, the swell stays in the 5ft to 6ft range, SW, with periods from 14 to 16 seconds. Winds remain offshore, mostly ESE or SE, 9 to 16 mph. Consistent, clean, good for experienced surfers. Energy dips a bit to around 1157-1707, but still moderate.

Thursday, September 17, the swell is 6ft SSW, 14 seconds, offshore in the morning, then cross-offshore in the afternoon. Still clean. Friday, September 18, the swell drops to 4ft in the morning, then 6ft in the afternoon – a bit of a lull, but still offshore wind in the morning makes for a glassy session.

Now, the real kicker: Saturday, September 19, the swell jumps back to 8ft SSW, 16 seconds, energy 2799, with gentle offshore ESE wind. Sunday, September 20, is even bigger – 8ft SSW, 16 seconds, energy 3931, and offshore wind again. These are excellent for experienced surfers.

But the absolute standout is Monday, September 22 – the last day of the forecast. The swell jumps to a massive 10ft from the SSW, with a 20-second period – that’s very long period groundswell, and energy is a whopping 9187, very strong. Wind is light offshore SE at 6 mph – glassy. This is exceptional for expert surfers only. The afternoon gets even bigger: 12ft SSW, 19 seconds, energy 9875. This is the best on offer, but it’s for experts only. The reef will handle it, but it’s a serious session.

Balangan is a consistent reef break, and crowds are possible – it’s a well-known spot. The standout days are the mornings of September 11, 13, and 22, with the 22nd being the absolute peak. The whole period is solid, but those are the ones to circle.

Rusty.
