Java, Bali, Lombok, Sumbawa forecast by Craig Brokensha (issued Thursday 6th August)

Best Days: Later Monday onwards

This week and next week (Aug 7 – Aug 14)

A slight kick in background S/SW is due this afternoon and this will ease into tomorrow, with exposed spots the go early under variable winds, strengthening from the E/SE through the day. Sets should be in the 3-5ft range early.

The weekend will be small and inconsistent, but our S/SW groundswell pulses due from later Monday next week are still on track.

A strong polar frontal progression is currently generating a good S/SW groundswell for Tuesday, but a front shedding off this progression and projecting north-east towards us over the coming days will help kick up a more consistent and larger increase in size for Tuesday.

We should see exposed breaks build to 6-8ft through Tuesday, easing back slowly from a less consistent 6ft+ Wednesday.

The easing trend will be stopped into Thursday as a reinforcing S/SW groundswell fills in, generated by a broad but relatively weak trailing front behind the main progression, keeping exposed spots kicking to 6ft.

A temporary low point is due Friday morning, but an afternoon kick in new long-range S/SW groundswell from continued strong frontal activity to the south-west of WA is expected.

Exposed breaks should kick back to the 6ft range on the sets and then ease into the weekend.

Longer term we may see a larger S/SW groundswell for the region early the week of the 17th, but we'll have a closer look at this on Tuesday.
