General
the sun is splitting the stones
What does the sun is splitting the stones mean?
It's blisteringly hot outside. Used for the rare Irish day when the sun is genuinely punishing — temperatures over about 22°C qualify, anything over 25°C is basically a national event. The image is sunshine so fierce it's literally cracking the stones in the wall.
"Get out of the house, would you — the sun is splitting the stones."
Origin
Traditional Hiberno-English idiom, likely from rural observation of stone walls heating and cracking in summer sun. Survives because Ireland gets so few hot days that when one arrives, ordinary language won't do.
