Hard choice even for me.
I'm not picking either at the moment.
I would give a slight edge to Geraldton vs. Brisbane
but north of Geraldton easily beats Brisbane
I've been in Western Australia since Feb 2011.
Because I get used to the heat of the sun,
I almost always feel cool or cold within +2/-2 hrs from sunset, in any season.
I loved how it almost never rained up to mid-May.
It's been raining more often than I'd like, usually, ever since June.
Sometimes I enjoy how low the humidity is in SW Oz,
but sometimes I miss the smells and warm evenings higher humidity brings.
In SW Oz
Any day with strong sunshine and light winds, (even winter
)
or strong sun, 25+ C/77+ F temps and any kind of wind feels superb, midday.
I might end up resenting Brisbane, if its humidity usually means cloud forms just in time to block high-angle sunshine.
Does it???
