Last night in Palermo, Sicily, Italy, it rained.
Rain is scarce during summer, and droughts are common.
The rain last night brought cooler air, and this morning, the temperature is below 30°C (in summer, it is usually around 30°C; in winter, around 13°C; and in the intermediate seasons, around 20°C).
To me, this suggests that a cooler season is on its way:
“In Italy, you know summer is over when the Nutella in the jar thickens up.”
