2. The leaves are only just turning - and that doesn't look like
'standard' autumnal turn either, but more drought stress (remember, we
haven't had the rainfall other parts of the country have had). The vast
majority of leaves are full (though deep) green, which doesn't suggest
autumn to me. I suspect though that within 7 days, this facet will
change dramatically.

If you are going to use this measure, wouldn't it mean that in many
recent years autumn wouldn't have begun in the south till the second
half of October?
