The Lowdown

IMPERIAL

Alright mates, Rusty here. Let’s break down what’s happening at Green Ball for the next 16 days.

First thing’s first – it’s a long, dry spell. The water temp is a normal 80°, no drama there.

The nearest we get to a surfable wave is on the morning of Saturday, July 26th, but it’s a real struggle. There’s a 8ft SE swell, but it’s a short-period 9 seconds. The wind is a messy cross-shore at 19 mph, and the wave energy is high at 1483, but the whole thing is too lumpy and cross-chopped to be any fun. It gets worse from there with onshore winds. Honestly, the period from the 25th of July right through the end of the month is a total write-off.

The one and only standout in this whole outlook is the morning of Monday, August 3rd. It’s not huge, but it’s the only clean window we’ve got. Expect a 6ft SSW groundswell with a nice, long 15-second period. The wind finally swings around to a clean cross-shore from the ESE at 12 mph. The wave energy is moderate (1379), and the SSW direction is spot-on for Green Ball’s reef. It’s a 2/10 in the scoring, but that’s a win in this forecast. The long period will give you some proper shaped waves on the reef, and with that cross-shore wind, it could be glassy. This is your one chance.

After that, it’s back to onshore junk. The swell actually gets massive – we’re talking 10ft from the SSW on Thursday, August 6th with a super long 18-second period and wave energy through the roof at 4823. But the wind is a constant 16 mph cross-onshore. For a reef with that much power and that wind, it’s going to be a miss. Frankly, it’s more of a kite-surfing window than a paddle-surfing one with that setup.

The entire second week is a tease: plenty of swell in the water, but always getting chopped up by the wind. It’s a frustrating one. Mark your calendar for that Monday morning on the 3rd.

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.
