The Lowdown
G’day, Rusty here. We’ve got a ripper run ahead at Outside Corner. This is a reef and point setup, exposed to the swell, and it’s looking like a solid stretch for the advanced crew. The water temp is sitting around 79°, which is about average for this time of year—nothing out of the ordinary there.
The first recommendation kicks off on Wednesday, September 16th. It’s not a world-beater to start, with a clean 6 ft swell from the SSW at 14 seconds, but it’s a cross-off breeze and the combined energy is strong at 1322. A decent warm-up.
Thursday, September 17th, is where things start to fire. That Thursday morning session is the first standout: a clean 7 ft SSW swell, period at 14 seconds, with a gentle offshore breeze from the SE. The energy is very strong at 1766, and it’s glassy—this is prime for the experienced surfer.
Friday, September 18th, holds a clean 5 ft SSW groundswell in the morning, period 14 seconds, gentle offshore, energy 993. Still quality, but the real juice comes back on Saturday morning, September 19th. Another 4 ft SSW swell, 14 seconds, moderate offshore, with a big energy jump to 1260. It’s clean and lined up.
The absolute standout of the whole forecast is Sunday, September 20th. Both morning and afternoon are exceptional. Morning: 7 ft SW swell, period 16 seconds, gentle offshore, energy a massive 2092. Afternoon: 7 ft SW, 16 seconds, moderate offshore, energy 2139. This is long-period groundswell, so at a reef and point like Outside Corner it’ll be a thing of beauty—long, powerful walls with clean faces. Experts only, but this is the best on offer.
Monday, September 21st, keeps the run going with 6 ft and 6 ft SW swells, both with gentle offshore breezes and energy around 1300-1500. Tuesday, September 22nd, dips a bit in size but the Tuesday afternoon brings a sneaky 3 ft SSW swell with a very long 18-second period and energy of 1141—that’ll be smooth and fat.
Wednesday, September 23rd, is another cracker: 7 ft SSW swell, 16 seconds, moderate offshore, energy 2257. That’s a big, clean day. Thursday, 24th, holds 6 ft and 5 ft SSW swells, all offshore and clean, energy around 1000-1200.
Moving into the second week, Friday, September 25th, offers consistent 5 ft SSW swells, energy around 800-850. Saturday, September 26th, is interesting—the morning has a tiny 3 ft SSW swell but with a very long 22-second period and energy of 1310, then the afternoon jumps to 7 ft SSW at 20 seconds, energy 4068. That afternoon is powerful but with a cross-off breeze.
Now, the biggest call of the whole outlook: Sunday, September 27th. This is the true standout of the entire 16-day window. The morning delivers a solid 10 ft SSW swell, 18-second period, moderate offshore from the SE, and combined energy of 6008. The afternoon is 10 ft SSW, 18 seconds, gentle offshore, energy 5236. This is expert-only territory—over 8 ft and cranking. It’s exceptional, but you need to know what you’re doing. If you’re not an expert, stay on the beach for this one.
Monday, September 28th, sees 8 ft and 7 ft SSW swells, 16 seconds, energy 2632 in the morning. Still a big day, but the afternoon is cross-off. Tuesday, 29th, holds 6 ft and 6 ft SSW swells with moderate offshore winds and energy around 1400. Wednesday, 30th, offers 5 ft and 5 ft SSW swells, still offshore and clean, energy 1097 to 1460.
Finally, Thursday, October 1st, wraps it up with a bang: morning brings 7 ft SSW swell, 17 seconds, moderate offshore, energy 3409. The afternoon is 8 ft SSW, 17 seconds, cross-off, energy 3110.
Overall, there’s no gap of dead days here—this is a constant run of solid, clean swell. The standouts are Sunday, September 20th, for the perfect long-period groundswell with offshore winds, and Sunday, September 27th, for the absolute power and size. Crowds are sometimes an issue at Outside Corner, so if you can get in early on those Sunday mornings, you’ll be laughing.
Stay safe out there.

Information about the Outside Corner Surf forecast
The above surf forecast table for Outside Corner provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Outside Corner can be found by selecting the local surf guide option on the grey menu. Our Outside Corner 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 (Outside Corner) 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 Outside Corner 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.
Outside Corner is 15 km (9 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.
