Java, Bali, Lombok, Sumbawa forecast by Craig Brokensha (issued Thursday 5th May)

Best Days: Off season breaks tomorrow through Monday, swell magnets next week

This coming week and next (May 6 – 13)

Great conditions the last few days with solid S/SW swell and variable winds. Photo of Day 2 of the Komune Bali Pro yesterday.

This morning we're in between swells, but the fore-runners of a strong new long-period S/SW groundswell will start to build across the coast today, kicking this afternoon and likely reaching 6ft+ by dark at swell magnets.

A peak is due tomorrow morning to a large 6-8ft+ across exposed breaks, easing back slightly through the afternoon and further down from the 5-6ft+ range Friday morning. The swell will continue to ease Saturday and Sunday becoming small and bottoming out through Monday afternoon.

Our variable winds will continue into tomorrow, with unseasonal W'ly breezes on Saturday, lingering Sunday before tending more variable early next week. This will be related to a weak tropical low off the North West Australian coast tracking north-east towards us.

Some new acute S'ly groundswell is due into Tuesday and Wednesday from a polar front currently pushing up towards WA, but the size off this will be limited with inconsistent 4-5ft sets due across swell magnets Tuesday afternoon and Wednesday morning.

From here there's nothing significant at all due into the end of the week or next weekend, but a series of large S/SW groundswells are on the cards for the week starting to 16th of May.

This will be from a flurry of strong polar fronts firing up in the southern Indian Ocean, but more on this Tuesday.
