I’m not just making this up. The National Oceanic and Atmospheric Administration (NOAA) and other weather nerds have crunched the numbers. For North America, July is the hottest month on average, with temperatures peaking around July 15th to 20th. That’s why it’s called the dog days of summer—because even the dogs refuse to go for a walk.
In Europe, the same pattern holds. Paris, London, and Rome all see their highest averages in July. It’s the month where historical buildings are like, “Please, no more selfies, I’m melting.”
But here’s the fun twist: climate change is making this a bit wobbly. Some places now see August or even September heat waves. But don’t let that confuse you—July is still the classic hot month, the one our ancestors complained about before air conditioning.
