Okay, I know that sounds like a ridiculous question, but here's why I ask: Anyone familiar with downtown Seattle knows that even on lovely calm days elsewhere in the city, it can be skirt-liftingly windy downtown. Something about the tall buildings creating a wind tunnel effect. So I was planning to take a lightweight skirt along to Paris (second half of September), but if Paris is generally a windy (or even just breezy) place, I think I'll leave the skirt at home. :-)
P.S. The last time I was in Paris, it was November, and it was most definitely windy (and incredibly cold), but I was all bundled up, so it didn't matter.
