In a few weeks, I'll be setting out on a westward crossing of the Great Australian Bight (from Kangaroo Island). Our plan is to coastal hop as far as Fowlers Bay, SA, before heading for Daw Island or Middle Island, WA. If the conditions are suitable, we might put in at Eucla.
From what I've learned, November thru March is the best time as the prevailing winds are moderate with an easterly component., i.e., what we're seeing now (below).
Any tips from sailors who have made this crossing would be appreciated.
