Can anyone tell me when is the worst/best time of the year to cross the Nullabor from the west in regard to headwind/tailwinds.
Hope that makes sense, but am trying to plan a round Oz trip starting in about 12 months time, my plan was to go in an anti clockwise direction from the east coast so as to be able to chase the sun at that time of the year, then work our way into WA then down to
Perth and
home via SA, taking about 12/18 months to complete the circuit.
So what I am really asking is what months does the wind traditionally blow to the east from WA, so that I can avoid headwinds and therefor excessive fuel consumption.

Just allow yourself plenty of time; if it is blowing a gale from the West (as it the reputation of the Nullabor although we haven't found it so), stop for a day or two, or just drive slowly and
camp early. We have met winds from both directions, but by far the worst was when we heading East in January after we left
Wudinna, and straight into a strong south easterly wind. We stopped very early and by next morning the wind had died down. I'm sure on the scale of a whole Oz trip, the additional fuel if you drive into the wind on the Nullarbor would make very little difference.

Mate, are you fair dinkum?
As South Oz receives an Easterly most of the time, I guess you could be "blown" across any time you like.
But what happens when you go up the east coast to FNQ. That's all up
hill isn't it?
And then you have to get from the East to the West again. Does the "wind" blow in the opposite direction in the top end?
Sorry Cruiser, just my warped sense of humour playing up on night shift tonight/this morning. Just ignore me.

Thanks everyone for your replys and opinions.
Given the time of the year I will be leaving, anti clockwise is the way to go I think, that way I can chase the sun in winter and will worry about coming east when we are ready, as we dont know when that will be.
That will depend on many things and I suppose that when all is said and done that if you have decided it is time to head towards
home, who cares how much it costs.
Thanks

Another 2 bobs worth.We did the top end and WA anticlockwise in Aug/Sept 05. Nice tailwinds up the centre but locals warned of the nasty headwinds if you go east acroos the Barkly. Back in April 99 had a
Tarago towing a Jayco Swan. Going west from
Erldunda to
the Rock we were blown along and could do 120kmh. But coming back into it sometimes it was a strain to do 85.
Another surprise is the strong SW from
Exmouth down to
Geraldton. Staying at
Denham we got a spot sheltered by some trees. When we left another couple moved straight in as their spot was too windy!!
It takes so long to cross Oz either Heading E or W that you're bound to get headwinds. Maybe they'll die out when you
camp overnight as a previous post mentioned. Early Aug last year and we were heading into a shocker between
Wilcannia and
Broken Hill. My LPG only gave 175km for 50 litres - same van but towed by a Pathfinder. with a good tailwind the same gas gives 210km. From
Perth to
Esperance in Oct 05 had great tailwinds for the days journey of 715km. The trees were bending over revealing interesting colours. But two days later from
Eucla to
Yalata we ran into a SE headswind. Overnight it died and next day heading into
Ceduna it was a NW tailwind. Whatever happens take it easy and enjoy it. Cheers Warrie
