You know it’s hot when …
… the sheep on the edge of the moors are all clustered in the areas of shade.
… the heating on the bus apparently can’t be turned off!

(For international readers, we Brits use the phrase Indian Summer to describe a spell of hot, sunny weather coming after summer is supposed to have ended. Just about late September it’s pretty usual).
