What to Pack (culled from the Web):
March in Paris remains somewhat chilly, with temperatures hovering at around 45 degrees F on average. It's a good idea to pack clothes that you can layer in case an unusually cool or warm day sneaks up on you. You can bring light cotton shirts and pants in hopes of sun, but also pack a few sweaters, warm socks, a scarf and a spring coat.
March can be a wet month, and Paris is known for its erratic and sudden downpours. An umbrella might be a good idea.
Make sure to pack a good pair of waterproof shoes. Rain during a March trip to Paris is likely.
