The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a solid 16-day window to look at for Green Ball, but I’m not gonna lie to you – it’s a tough stretch. The ocean is pumping a lot of energy, but the wind is just not playing ball for most of it.
The first real action to talk about kicks off on Tuesday, July 14th. The water is sitting at a warm 81°, which is pretty much spot on for this time of year, so no worries about a wetsuit here. The swell is coming in from the SSW, which is exactly what this reef break wants to see. For Tuesday morning, we’ve got a 6 ft SSW swell with a very long period of 17 seconds, packing a hefty 2972 units of energy. This is a proper groundswell. That long period means the waves will have plenty of shape and power, but at a reef break like Green Ball, it’ll be working well. The problem is the wind. It’s a cross-shore ESE breeze at 16 mph, which is creating a cross-chop and making the surface lumpy. It’s not horrible, but it’s not the clean, glassy perfection we dream of. The tide conditions are also questionable, so it’s a bit of a gamble. Still, this is the best looking morning of the whole run.
The afternoon of Tuesday the 14th turns worse as the wind swings cross-onshore, so forget that. Wednesday the 15th morning is a similar story – a 7 ft SSW swell at 16 seconds (2228 energy), but again that same lumpy cross-shore wind. The rest of the week from Thursday the 16th through the weekend is a write-off. The wind stays cross-onshore, the swell drops a bit, and the conditions are consistently poor. The energy is still there, but it’s all chop and no shape.
We get a slight reprieve on Monday, July 20th – the swell bumps back up to 7 ft from the SW (2796 energy), but the wind is still cross-onshore and choppy. It’s a shame, because that’s a decent amount of juice. By Tuesday the 21st, it’s the same story.
Honestly, from the 14th all the way through to the 29th, we’re looking at consistent cross-onshore or cross-shore winds that are just ruining the surface. The surf is there, but it’s mostly poor conditions. The standout period is really that Tuesday morning, July 14th, if you can handle the lumpy cross-shore wind and catch the tide right. The swell is big, the period is long, and the reef will handle it. But if you’re looking for clean, silky waves, you’re going to be waiting a long time. The swell fades completely by the end of the month, dropping to 2 ft on the 28th with next to no energy (187).
Forget the afternoons. The only window is the mornings, and even then, it’s marginal. This is a period for the die-hards with a high tolerance for chop. If you’re a beginner, this 7 ft+ swell is too big, and the conditions are too messy anyway. Stick to the flat days.
That’s the picture from Green Ball. Not a classic run, but a few windows if you’re desperate for a paddle.
Rusty.

Information about the Green Ball Surf forecast
The above surf forecast table for Green Ball provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Green Ball can be found by selecting the local surf guide option on the grey menu. Our Green Ball 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 (Green Ball) 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 Green Ball 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.
Green Ball is 14 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.
