Java, Bali, Lombok, Sumbawa forecast by Craig Brokensha (issued Tuesday 26th April)

Best Days: Every day over the coming period (experienced surfers only Wednesday, Thursday, Friday, Monday, Tuesday)

This week and weekend (Apr 27 – May 1)

Sunday's good new S/SW groundswell came in as expected with great waves across the Bukit and more exposed breaks. This swell eased back a touch later in the day and further into yesterday.

Today an inconsistent SW groundswell has boosted wave heights back to an inconsistent 4-6ft across swell magnets with variable winds before E/SE trades kicked in.

Into tomorrow our large pulse of S/SW groundswell from an intense mid-latitude low (satellite observations right) is looking good, with the swell impacting the WA yesterday and reaching a stormy 10ft through the day.

This swell will fill in through tomorrow, peaking into the afternoon/evening with exposed breaks due to reach 6ft to occasionally 8ft before easing back from the 6ft+ range Thursday.

This easing trend will be slowed by a weaker but secondary cold front pushing up on the tail of the low, producing a reinforcing S/SW groundswell for Friday, keeping 5-6ft sets hitting exposed spots, easing back into the afternoon and further Saturday, bottoming out Sunday evening.

The E/SE trades will persist until Friday (variable each morning) before backing off into Saturday, tending more variable and remaining so through most of next week.

Next week onwards (May 2 onwards)

We've got some fun S/SW groundswell pulses on the cards from Monday as a series of strong cold fronts push up and into the South West of WA.

The first is due to fill in Monday with a second similar sized pulse for Tuesday.

Exposed breaks should kick to 6ft+ Monday and hold Tuesday with 8ft sets likely at times both days before the swell starts to ease later Tuesday and more so Wednesday.

Another pulse of smaller S/SW groundswell may be seen late week, but we'll have another look at this Thursday.
