Freezing in March
That's always a big question. Half the people I ask, including my cousin who lives there, says "No" (That's also because she won't be there!) Then there's the other half that say, "Yes! It's still Paris!"
Most Parisians leave the city in August to take their annual vacation. A few years ago, our July trip in Paris went into the first week of August and I didn't notice anything different. But a few recent emails back and forth to a respected dealer at the Clignancourt flea market revealed that she and other dealer friends will be out of town from the "second week of August til the 29th", and that the flea market will of course be open, but will be "quieter" in August.
