The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Balangan over the next couple of weeks. It’s a reef break that’s fairly exposed to the south-west swell, and it’s consistent, which means we’ve got plenty to look at. Water temp is sitting about average for this time of year, so nothing weird going on there.
Right off the bat, we’re in for a solid run starting Monday the 17th of August. The morning kicks off with clean 5ft SSW groundswell, period at 14 seconds, and that moderate offshore breeze from the ESE is keeping things tidy. Wave energy is moderate (911), and it’s good, surfable stuff for a beginner-friendly reef. The afternoon stays similar, just a touch smaller at 4.6ft.
Tuesday the 18th is where it starts to get a bit more serious. Morning sees the swell push up to 5.6ft from the SSW, period jumping to 16 seconds, and the energy ramps right up (2883). This is excellent surf for experienced surfers. Wind holds offshore and clean. Afternoon stays similar at 5.6ft from the SW.
Wednesday the 19th is the real standout of this whole stretch. Morning brings 7.9ft SSW groundswell at a long 18 seconds, and the energy is strong (3575). By the afternoon it hits 8.2ft from the SSW with a 17-second period, and energy is very strong (4103). That’s proper groundswell, and with the ESE offshore wind, it’s going to be pumping. Now, at this size, it’s expert territory—over 8ft is not for beginners. Long period like that (over 15 seconds) means the waves will have plenty of punch and shape, but at a reef like Balangan, that’s a good thing. Expect longer lulls between sets, which makes the paddle out easier, but when they come, they mean business. Crowds are possible here, and on a day like this, they’re likely.
Thursday the 20th holds steady—still 8.2ft in the morning from the SW, 16-second period, strong energy (3700). Afternoon is similar at 8.2ft. Wind stays offshore and clean.
Friday the 21st drops back a bit in the morning—4.6ft SSW at 18 seconds, but the energy is still strong (2685). The afternoon brings back the size to 7.9ft SSW, 17 seconds, and energy is very strong (3576). Conditions remain clean with offshore wind.
Saturday the 22nd is still good, with 7.2ft SSW in the morning, 16-second period, moderate energy (2433). The wind is offshore and clean. By the afternoon, it shifts to a cross-offshore breeze, still clean but not as lined up.
Sunday the 23rd starts clean again with 6.9ft SSW, 15-second period, and moderate energy (2061). Afternoon goes cross-offshore again.
Monday the 24th: morning is 6.6ft SSW, 15-second period, clean with offshore wind (1883). Afternoon turns cross-offshore, swell drops to 5.9ft.
Tuesday the 25th sees some clouds roll in, but the swell is still 5.6ft in the morning, 14-second period, moderate energy (1262). Wind remains offshore and clean. Afternoon drops to 4.9ft.
Wednesday the 26th: size drops to 4.3ft SSW in the morning, 13-second period, energy is lighter (601). Still clean with offshore wind. Afternoon goes to 3.6ft from the SW.
Thursday the 27th: morning is 4.6ft but with a cross-offshore breeze, period only 12 seconds (1106). The afternoon jumps back up to 5.9ft SSW, 15-second period, energy moderate (2066), and wind goes offshore again—clean conditions return. This is a nice little late-week pulse.
Friday the 28th: morning is 7.2ft SSW, 14-second period, light offshore breeze, clean (1941). Afternoon goes cross-offshore, swell holds at 6.9ft.
Saturday the 29th: swell drops fast—morning is 4.3ft from the S, cross-offshore, and the afternoon is just 2.6ft from the SSW, though the period is a very long 19 seconds (1262). Not much push.
Sunday the 30th: morning picks back up to 4.3ft SW, very long 19-second period (1504), clean with offshore wind. Afternoon holds at 4.6ft SW, 18-second period, with strong energy (2292). That’s a promising end to the run.
Monday the 31st: morning is 5.2ft SW, 17-second period, cross-offshore but clean (2028). Afternoon is 5.6ft SW, 16-second period, still cross-offshore.
Tuesday the 1st of September: the run fizzles out. Morning

Information about the Balangan Surf forecast
The above surf forecast table for Balangan provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Balangan can be found by selecting the local surf guide option on the grey menu. Our Balangan surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Balangan) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Balangan may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Balangan is 10 km (6 miles) from the city of Kuta. If you plan a holiday in The Bukit - Bali, look for hotels and other accommodation in Kuta. Kuta has rooms for a wide range of budgets as well as car hire and transport links.
