Paris in spring is everything they say — but pack layers. I learned the hard way that a sunny morning can turn into a chilly afternoon by the Seine. April temperatures hover around 11°C but feel cooler near the river. Skip July if you hate crowds; late May and early June give you warmth without the tourist crush. And always, always carry a compact umbrella.
