I am thinking to visit Paris at the end of August(Aug,23-Aug,30)..

Question

What kind of weather do I have to be prepare for? Should I expect a lots of rainy days? Do I need to bring warm clothes?

Answer 1

In August in Paris, the weather is not stable at all, a little of wind, often cloudy, sometimes clearing. The temperature vary about 20 degree (in french way). So one or two wind-break will be useful. Aside this, T-shirt of long and short sleeves will be ok.

Answer 2

Expect daytime high temperatures in the mid to high 70's and evening  low's in the mid 50's.

The temperature right now is 73° and the forecast for tomorrow is a high of 71° and a low of 53°.

Whether this is cool enough to require warm clothes is a matter of your personal tastes.
