Alright mates, Rusty here. We’ve got a long, frustrating forecast for Green Ball. The swell is there, the wind ain't. Over the next 16 days, there’s really only one marginally okay window, and it’s a long way off.

Kicking off Saturday July 5th, we’ve got a solid 7ft SSW groundswell with a 15-second period – that’s proper energy (1974), but a 12 mph cross-onshore easterly has it all blown out. Water’s 81°F, about normal for this time of year, but that doesn’t help the chop.

That first week? Don’t bother. Swell runs from 5ft to 7ft, all from the SSW, long periods of 14-16 seconds, but every single session has 12-22 mph cross-onshore winds from the ESE or SE. The energy peaks at 2572 on Wednesday July 9th – that’s a lot of ocean moving, but it’s all lumps and bumps. This is more for kite surfers than anyone on a paddle board.

Our first real "maybe" is Sunday July 12th. Swell drops to 3ft from the SW (13 seconds), energy down to 560. It’s cross-shore, not fully onshore, with a 12 mph breeze. It’s marginal at best, especially in the morning. The afternoon brings a 5ft windswell from the SE with only a 6-second period – a total mess.

From July 13th to July 16th, we bounce between 3ft and 6ft, but it’s the same story: 12-19 mph cross or cross-onshore winds, moderate energy, and lumpy surface.

By July 17th and 18th, the swell is 4ft to 4ft from the SW with 16-second periods, but the ESE wind still won’t let up. Energy drops below 1000 by July 18th. The last couple days, July 19th, are flat: 3ft SW swell and weak 13-second periods.

The only session I’d point to is Sunday July 12th morning at Green Ball. It’s a reef break that loves SSW swell, and we get that direction off and on, but the wind is never right. This spot is fairly consistent when conditions click, but not with this wind. It’s exposed to every bit of that easterly breeze. Crowds can happen when it’s good – but that’s not now.

Overall, this is an unusually long stretch with no good waves. It doesn’t normally stay this poor for this long, so things could change. But right now, I’d take a break.

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.
