Long Range GFS Charts - Indian Ocean

So I take it then by the lack of response, no such information exists on the free public domain?

Don, generally I find 180 hours more than enough, as the models hardly tend to agree out this far.

And if they do agree, any swell being generated in the Indian Ocean at the end of the run, will hit WA/SA and Vicco 2-4days later, and 5 days up towards Indo generally. So you already have a 300hr forecast just by using the already available charts.

Thanks Craig, but I'm more keen to see if GFS is agreeing with the long range EC models for swell in early April.

Hey

I'm looking to better understand where in the Indian Ocean the strongest Indo swells come from. My understanding is l should be looking for blobs in the 50E to 70E - 40S range. Depending on the fetch angle obviously. But l have no real idea..........

Hoping to be able to pick a couple of solid Bali swells nice and early for hit run missions

Thank

Sarge, how long is a piece of string. So many variables for swell production in the Indian Ocean that you really can't lock in a specific latitude longitude window. Best to look at the charts (all weather models, EC, GFS etc), identify a damn impressive fetch along the great circle path from Bali and if all the planets (and models) align, then jump on the plane!!!! Obviously, the bigger and stronger the fetch and closer to Bali the better, although some impressive super long period SW groundswells can certainly be created well beneath South Africa.

For instance the storm that's progged to form to the SW of Heard Island early-mid next week (GFS charts) looks set to deliver a very nice period SW groundswell to Bali around Sunday 22nd May and beyond.

Thanks Donweather

I'll keep a close eye on this storm and see what l can learn

Cheers
