Java, Bali, Lombok, Sumbawa forecast by Craig Brokensha (issued Tuesday 4th August)

Best Days: Friday morning exposed breaks, Tuesday onwards

This week and next week (Aug 5 – Aug 14)

Late last week and over the weekend a good S/SW groundswell offered decent waves across most breaks, and this has eased back into the start of the week, with a reinforcing but inconsistent and acute S'ly groundswell filling in today.

The swell will drop back through tomorrow, and only a small kick in infrequent background S/SW groundswell is due into Thursday afternoon reaching 3-5ft at exposed breaks, before easing Friday and further into the weekend.

The trades are due to strengthen again into Thursday before relaxing into Friday and the end of the week and persisting in the moderate to fresh range next week.

Swell wise, we're finally due to see some better S/SW groundswell across the region into the start of next week, as a strong and multi-stage polar frontal progression fires up south-east of South Africa today and pushes slowly east over the coming week generating winds in the gale to severe-gale range.

A series of inconsistent S/SW groundswell pulses should result, the first arriving Tuesday, with a secondary pulse for Wednesday. Exposed spots are due to pick up 6ft to possibly 8ft sets during the peak of the swell before dropping back Thursday and into the end of the week.

Longer term the models diverge on the outlook into early the week of the 17th, so we'll have a closer look at this on Thursday.
