Today's seasonal word: Morning cold

Today's seasonal word: Morning cold
The quietness is permeated with the signs of the season.
When I woke up in the morning and opened the window,
The cool air caresses my skin.
It was a coldness that cut off the last traces of summer.
But somehow it feels comfortable,
It signals that the season is deepening.
A cold morning is not just a change in temperature.
It's a moment when the quality of time changes.
The color of the sky, the sound of the wind,
Everything becomes a little quieter.
This season word includes:
The "coldness of the beginning" and the "lingering feeling of the end" coexist.
It can only be felt on autumn mornings,
There's a sense of transparency there.
— A chilly morning, the seasons quietly awaken.
