End of the wind cycle????

When there is high to the west, west coast. when it shuts off and the high is all the way over near South Australia there is an opposite direction seabreeze - a SE afternoon wind - on the south coast. so west coast seabreese is southerly, and a south coast sesbreese is SE. it's not that long it's a week ish cycle.
If you can alternate Geraldton and Esperance as needed it would be an epic trip, but not many ppl want to do the driving.
do the driving !

I wouldn't normally look much further out than 3 days. Sure it might give an indication about what could happen but it can and often does change.

You're pretty much guaranteed with wind this time a year especially if you don't mind driving.

Let us know how you go!

Don't drive at night!!!!
There is too much wildlife.
It can happen anywhere.
I drive trucks at night and I know!!
