Slow period ahead of large swell Friday week
Java, Bali, Lombok, Sumbawa forecast by Craig Brokensha (issued Thursday 9th April)
Best Days: Every day exposed breaks, and then from Friday week for bigger surf
This weekend and next week (Apr 10 - 17)
Fun levels of inconsistent S/SW groundswell have keep exposed breaks topped up with good waves yesterday and today, with a similar sized pulse due tomorrow to an infrequent 3-5ft before easing through the weekend.
Into next week there's nothing major due until Friday with background levels of inconsistent SW groundswell due to keep 3ft+ waves hitting swell magnets. Winds will remain favourable and light offshore early with weak E/SE trades into the afternoons.
Friday however will see the arrival of a strong and powerful long-period S/SW groundswell, generated through the southern Indian Ocean. This will be the result of a strong node of the Long Wave Trough moving through the southern Indian Ocean, projecting two vigorous polar lows through our swell window. The first system will develop south-east of South Africa and generate a fetch of severe-gale to storm-force W/SW winds while tracking towards WA.
A secondary strong system will then fire up on the tail of the original low, generating a secondary strong S/SW groundswell for later Saturday and Sunday.
Size wise we should see large 6-8ft+ waves at exposed breaks through Friday, dropping a touch Saturday and then kicking back to a similar size Sunday. Winds look great with variable morning breezes and fresh afternoon E/SE trades.
Longer term the outlook remains active into the following week, but more on this Tuesday.
