But we've reached the autumn equinox and from now on we're heading for winter, whatever the current temperatures are telling us. This is the time of the "transumanza" - when, in Italy, the flocks of sheep and cattle would traditionally be brought back from their summer pastures in the mountains to lower and milder climes. We may be lucky and ease in gently - tradition has it that the weather between the 21st and 23rd of September sets the pattern for the rest of the autumn - but it's time to get ready.
Even while we were at the sea earlier in the month, the clues were there. It still seemed like summer weather, but even when we arrived, the Virginia Creeper was telling a different story. And by the time we left, just over a week later, there was no way of pretending not to notice.
The squirrels in my garden know. They don't play any longer - all day they're back and forth, burying nuts. The warm weather hasn't fooled them. Hard times are coming.
The plants know too. Their blooms have given way to seed pods and berries.
And the trees know. It's already time to get the rake out.
Winter's on the way.
