Paris's summer weather is not nearly as bad as San Francisco's, but it ain't parfait. Today is a great example: 64 degrees and raining. Hailing, actually.
The funny thing is, if you say the words "summertime" and "France" to most people around the globe, they picture fields of lavender baking under the sun, bronzed jet-setters in expensive bathing suits lounging aboard pristine yachts — in short, they picture June in Provence or on the Côte d'Azur.
Yet most of France's visitors come to Paris, where they are more likely to experience a summer scene like this one:
Ah, les pauvres (the poor things)! Quand il fait moche (when it's nasty out), nobody is happy — which explains, I think, the Parisian mood in general. In the city, il fait beau (the opposite of moche) only occasionally. Which is why, when the weather is clement, the streets and cafés are packed with locals sitting, sipping and soaking up the sunshine.
