The Lowdown
G’day, Rusty here. Let’s break down the next couple of weeks at the only spot that’s showing—Outside Corner, a reef and point setup that’s exposed to the SW swell. Water temp is 80°, which is about average for this time of year, so no surprises there.
The action starts Monday, July 20th, with a solid SW groundswell. Monday morning brings 5ft from the SW with a 14-second period, and the combined energy is pumping at 2087—that’s strong, powerful stuff. There’s a fresh ESE wind blowing straight offshore, so the surface will be clean and glassy. This is advanced territory—5ft on a reef and point will have some bite, and crowds are possible. The swell builds Monday afternoon to 7ft from the SSW with a 16-second period and even more energy (2321). That’s big, proper groundswell, and with the long period, it’ll be a bit more challenging at the peak, but the point will handle it nicely. Tuesday, July 21st, keeps the goodness rolling: 6ft in the morning, 5ft in the afternoon, both SSW with 14-second periods, clean offshore winds, and moderate to strong energy (1340 and 1193). This is the standout window—Monday and Tuesday are your best bets. The swell slowly drops off through Wednesday and Thursday, with 3-4ft, still clean, but the energy slips into the 600-800 range. Still fun, just not as punchy.
Then we hit a bit of a lull. Friday, July 24th, has small 3ft SSW swell with a 17-second period in the afternoon—long period but low energy (761-846). The surf is marginal, but the offshore wind keeps it tidy. Saturday, July 25th, picks up a little: 4ft from the SSW, 15-second period, energy back over 1000. Not a standout, but a solid session if you’re keen. Then Sunday, July 26th, things get messy. The swell shifts to SE, drops to an 8-second period, and the wind cranks up to 22-25 mph. The energy plummets to 630-788, and the short period means choppy, lumpy waves. The offshore wind is still there, but it’s strong and hard to paddle into. This is more of a kite-surfing setup than a paddle session. Monday, July 27th, is similar—5ft SE windswell, short period, fresh offshore, but not great quality.
The second week looks more promising. From Tuesday, July 28th, we’re back to SW groundswell with 16-second periods, but small at 3-3ft. Energy is moderate (558-621). Wednesday, July 29th, bumps up to 5-5ft SSW with 14-15 seconds, energy back over 1000. Then Thursday, July 30th, is the real highlight of the second week: 5-5ft SSW with a 13-16 second period, but the wind drops to 16 mph, and the energy jumps to 1658-1751. The conditions are excellent for experienced surfers—clean, powerful, and lined up. Friday, July 31st, is also a beauty: 4ft SSW with a 17-18 second period, the wind drops to 9-12 mph, and energy is 1391-1731. That’s a very long period groundswell—gorgeous, but it’ll be a bit too straight for the beach if it was a beach break, but here at the reef and point, it’ll wrap in beautifully. Crowds are possible, but it’s worth it. Saturday, August 1st, keeps it solid with 5-5ft SW, 16-17 seconds, and moderate wind. The run then tapers off into Sunday and Monday with 5-5ft and 3ft respectively, still clean but not as punchy.
So, overall: the standouts are the first two days—Monday, July 20th, and Tuesday, July 21st—with solid SW groundswell, clean offshore winds, and strong energy. The second-week highlight is Thursday, July 30th, and Friday, July 31st, with excellent conditions but a bit more uncertainty given the range. The rest is fun but not firing. No major gaps in the surf, just a few days of weaker energy here and there.
Rusty out.

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.
