Indian Ocean Basin analysis by Craig Brokensha (issued Thursday 2nd November)

This week through next week (Nov 3 – 10)

Today's small lift in inconsistent S/SW swell is due to back off tomorrow, becoming smaller into the weekend.

As touched on in Tuesday's notes, next week remains slow with small, background levels of mid-period surf due to arrive from Tuesday, generated by weak polar fronts pushing through our far swell window.

At this stage it's hard to discern each pulse but we should see a small pulse of groundswell and mid-period energy Tuesday afternoon/Wednesday with a secondary pulse for later Thursday and more so Friday morning. None look to really push above 4ft on the magnets unfortunately.

A better swell producer looks to form around the Heard Island region on Monday, projecting a good fetch of strong SW winds towards Western Australia before weakening and continuing east out of our swell window.

A fun, moderate + sized S/SW swell is due from this source on Sunday/Monday the 12th/13th. We'll have a closer look at this in the next update Tuesday though.

Looking west to the Maldives, and slowly easing levels of SE trade-swell are due from today into the weekend thanks to slackening trades throughout the Indian Ocean.

Weak trades over the coming days will provide small to moderate levels of swell into early next week before the trades break down, leading to a further drop in size mid-late next week.

The fun background S'ly swell mentioned in the last update for Tuesday/Wednesday is on track, generated by a polar front that's currently south-east of South Africa. This is due to fill in Tuesday afternoon, holding Wednesday, then easing.

Eastern Indonesia:
