Table - best surf conditions forecast for Green Ball over the next 16 days.


Alright folks, Rusty here. Let’s have a honest look at what this stretch has for us. Straight up, I’ve got to tell you, the outlook for Green Ball over these next few weeks is pretty bleak. We’re looking at a long, frustrating run of poor conditions with hardly any windows worth paddling out for.

The main issue is the wind. It’s stuck in a cross-onshore or cross pattern, mostly from the ESE to SE, and it’s blowing with moderate to fresh strength for almost every session. That means the surface is going to be choppy, lumpy, and messy. The swell is coming from the SSW to SW, which is what this exposed reef break wants, but the wind completely ruins it.

The combined swell energy, while moderate to strong at times (like 1031 to over 3500), never translates into quality surf because of that relentless wind. Even when the swell drops to around 3ft to 3ft on July 12th and 13th, or pushes up over 7ft in the second week, it’s all just blown out.

There is no standout period here. From Saturday July 11th right through to Sunday July 26th, nearly every session is flagged with “poor surf conditions” or at best “marginal surf.” The only slight flicker of hope is on the morning of July 16th and the morning of July 24th, where the wind goes cross-shore and the conditions are labelled marginal. On July 16th (Thursday morning) we’d have a 6ft SSW swell with a 15 second period – that’s some decent energy (combined energy of all swells directed here sits at 1432) – but it’s still a cross-shore wind with chop. On July 24th (Friday morning) the swell is 5ft from the SSW, period 14 seconds, energy at 1828, but again, cross-shore wind and a lumpy cross-chop. Neither of those windows are clean enough to get excited about.

Green Ball is a reef break, advanced level, and it’s fairly consistent with exposure to the SSW swell. That’s all good on paper, but when the wind won’t cooperate, there’s just no way to enjoy it. Crowds are “sometimes” an issue here, but frankly, with conditions this poor, I doubt many will be out.

The water temperature is 81°F, which is about normal for July with a tiny anomaly of 0.5°. So that’s not going to bother anyone.

Honestly, this is one of those stretches where you’re better off keeping the boards in the car and waiting. A blank run like this is not unheard of for this area when the tradewinds settle in and don’t let up. Forecasts can change, but right now? It’s a hard pass.

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.
