Slow period continues, largest Friday

Java, Bali, Lombok, Sumbawa forecast by Craig Brokensha (issued Tuesday 21st July)

Best Days: Exposed breaks over the whole period

This week and next week (Jul 22 – 31)

Slow surf will continue through tomorrow with an inconsistent and small to moderate SW groundswell keeping exposed coasts active.

Into Thursday and Friday a lift in mid-period and bigger S/SW groundswell is due, generated by a broad but relatively weak polar front pushing up and into WA the last couple of days.

The swell should build to the 6ft range across exposed breaks Thursday afternoon/evening and then peak Friday around 6ft+ before easing into Saturday, bottoming out Sunday morning.

Weak trades will result in variable and favourable winds each morning across exposed breaks, before freshening into the afternoons.

Through Sunday afternoon a further kick in S/SW groundswell is due, generated by a slightly stronger, but smaller in scope, polar front currently pushing up towards WA. This swell will be more south in direction but again should reach 5-6ft across exposed breaks through the afternoon Sunday and then ease into Monday.

A much less consistent but long-period S/SW groundswell is due Tuesday across the region, produced by a strong but distant polar low in the Heard Island region. A fetch of W/SW gales should produce an inconsistent pulse to 5-6ft or so at swell magnets Tuesday before easing back into Wednesday with weakening trades.

Longer term there's still nothing significant on the cards to end the month, or heading into the start of August, but we'll have another look at this on Thursday.
