@Dave R; 15'/25' is what we get throughout the second half of Autumn and in early Spring.
From late May to early September it's usually cold, damp Winter woggle weather - Covid, flues and colds love us at this time of year.
I've just read an article on the unprecedented 'heat domes' frying the Northern Hemisphere's more northern countries this year - we sure hope that's not coming to us this soon after the 2019-20 bushfire season. Adding that to Covid would tip a lot of people over the edge of despair.
