Dubbo, Wagga Wagga and Albury (inner NSW) are very drought-prone. And Sydney isn't that far off.
Going north in Australia gives you more consistent summer rainfall, yet the relative humidities, even in deep Australia tropics, are quite low, as I showed with Cairns. Did those areas record some dry years that skewed the average?
I will have to say no matter how drought prone australia is, I love my australian ferns, maybe they just have adapted, I love these aussies. No rain for 6 days and brutal heat and everything is struggling but they just dont care, look as bright and magnificent as the day I bought them
Eastern Australia seems to have very low relative humidity levels, quite odd for wet, seasonal tropics; Cairns, for instance, has levels below 70% for the entire year, even during the wet season: https://en.wikipedia.org/wiki/Cairns#Climate
Those are not real humid subtropical climates; those areas only get classed as "humid subtropical" because they just can't fit with either Med, Oceanic, nor continental climate regimes as in the rest of Europe. You will not see them being classed as humid subtropical outside of Koppen: https://en.wikipedia.org/wiki/Humid_...climate#Europe
So what exactly is it that makes it not so, is it because the hot season isn't long enough, or the rainfall pattern, or both?
But the dry time in most monsoonal areas is winter, which is the season with least evapotranspiration (as temps are lowest); this means less chance of drought, especially if summer rains are consistent.
South Asia is a very extreme monsoonal pattern, with strong heat during the spring months. However, summers are very rainy, with some areas getting nearly 40 inches in a single month. The dryness, though, lasts long enough for me to place it behind the US South, and East Asia.
Drought isn't the same as dryness; drought is getting much less rainfall than average, or a measure of climate variabilty.

I should have been more specific; I meant that South Asia, although it relies on a monsoon, can have pre-monsoon heat season levels extending quite a long time, into what should be the rainy season. Just the chance of that prolonged dryness into the rainy stretch can make it more drought prone vs East Asia.
Yeah, the BOM only records humidity at 9am and 3pm, and on wiki they use the 3pm average as the humidity level.
Interesting. I checked the source, and found that you are correct, those charts only use 3PM levels. On the other hand, though, morning relative humidity levels are quite low (in the 70s for many areas vs up to 90% in the area like the SE US).
