The heat is on in Munich

Can you use that phrase when it comes to hot temperatures? Anyway, I think you know what I mean. Right now, it's close to 97 degrees Fahrenheit here in Munich (36 - 37 in Celsius). I understand it's even warmer in UK and France. Fortunately, I didn't have to drive that far today, just about 120 km. We will spend at least two nights here, waiting for the heat to cool off.
