Alright, Rusty here. Let’s have a look at what’s cookin’ at Bali Bay.
We’ve got a solid run of surf coming up, but it’s not all clean. The first real action kicks off Monday the 6th of July with a glassy morning showing a 7ft swell from the WSW at 11 seconds. The wave energy is strong, coming in at (1210). This is a powerful, long-period groundswell, and with the wind glassy from the NNE, the surface will be smooth. This one’s for the experienced crew – it’s got some weight to it. Water temps are about average for the time of year.
Tuesday the 7th keeps the quality high in the morning. A 7ft SW swell at 12 seconds with cross-offshore winds from the north will keep things clean. The energy is building (1334). Again, this is a solid intermediate-to-expert wave.
Wednesday the 8th gets mixed up. The morning’s a bit bumpy with cross-on winds from the SSW, and by the afternoon a 12 mph cross-shore from the SSE chops it up. Swell size drops to 5ft with a very long 16-second period. That long period at a reef break like Bali Bay can be a real treat, but with that moderate breeze, it’s not the day for perfection.
Thursday the 9th is all about size and wind. The morning has a 10ft SSW swell at 14 seconds, but with a 16 mph cross-shore, the surface will be messy. Wave energy is huge (3195), but the conditions are more for the die-hard expert or the kite crew.
Now, Friday the 10th – here’s a standout. Morning brings a 10ft SSW swell at 13 seconds with light cross-off winds from the ESE. It’s clean and powerful (2975). The afternoon holds 8ft with the same clean winds. This is the real highlight of the first week for experienced surfers.
Saturday the 11th starts with a glassy 7ft SSW swell at 12 seconds. That’s a beautiful combination (1582). The wave energy is right there. This is your call for a great session.
The second week starts to drop off. Sunday the 12th has much smaller 4ft swell. The glassy morning is nice for a longboard, but the energy is way down (586). Monday the 13th is similar – small and glassy in the morning (482). From Tuesday the 14th onward it gets weak, with swell dropping under 3ft.
However, there’s a late burst. On Tuesday the 21st of July, we see an 8ft SW swell at 15 seconds with completely glassy conditions and zero wind. The energy is huge (2988). This is a long-range standout – a promise of a big, clean, powerful groundswell at Bali Bay. That period over 15 seconds is very long, so the sets will be well-spaced, and the paddle-out easier. Mark that date.
But be aware: Bali Bay is sometimes crowded. There will be company on these good days. And for the big stuff over 8ft, that’s expert territory only.
So, the best bets: Friday the 10th and Saturday the 11th for the first week. The long-range call is Tuesday the 21st. That’s where the magic is written.
Rusty.
