Java, Bali, Lombok, Sumbawa forecast by Craig Brokensha (issued Thursday 30th July)

Best Days: Friday through Tuesday

This week and next week (Jul 31 – Aug 7)

There's been no change to tomorrow's and the weekend's S/SW groundswell pulses with exposed breaks due to peak tomorrow evening and Saturday morning in the inconsistent 6ft+ range.

A slow drop in size is due from Sunday and further into Monday.

Our acute and tricky S'ly groundswell for Tuesday is also still on track, with a vigorous polar frontal system firing up today to the south-southwest of Tassie, aiming a fetch of S/SW gales through our southern swell window.

The swell will hardly make an impact east of Bali, with a peak due Tuesday afternoon to the 3-5ft range, easing into Wednesday and further Thursday.

Moderate to fresh E/SE trades are due to continue, lighter and more variable early each morning.

Besides an inconsistent long-range SW groundswell for Thursday afternoon in the 3ft to possibly 5ft range, there's still unfortunately nothing major showing on the charts.

A large upper level blocking pattern (opposite to a strong node of the Long Wave Trough) will result in no significant storms moving through our swell window next week, with hopefully a break down in the pattern later next week.

We'll have a closer look at this on Tuesday.
