Weather in Paris and London at end of June/First week of July

It should be warm and you should prepare for thunderstorms.

It could be nice or it could be hot (80s) and very humid. Take something nice (unlined coat) to keep off the rain. It will probably rain some time each day. If its hot the humidity will be worse than Arkansas in my limited experience i may be a little old fashioned but you are in major cities- pants will work fine, but no shorts please

I would bring one pair of pants at least. They will be more fashionable than shorts and it can get colder at night even in June.

Someone on this board (Kent) pointed me to this weather underground site a couple of years ago and it is really useful for planning:
http://www.wunderground.com/tripplanner/index.asp You put in the location and a date range and it returns the last 10 years (or more) of weather history (temperatures, rainy days, etc.).

Always a crap shoot to predict weather, but one year I was in both Paris and London in August. In Paris it started off very hot (mid 90s) but lasted just 2 days, the rest of the two weeks I was there it varied from comfortable (low 70s to low 80s) to a few days when it was rainy/cold and I actually needed a jacket during the day when I was outside. August in London that year it was hot just 1 day, the rest of the 2 weeks in London was cold enough to consistently need to wear a jacket and long pants whenever I was outside during the day. In my opinion, in cities like Paris & London, you'd look a little more put together yet still stay just as cool if you brought along a cotton dress or skirt, capri pants or lightweight long pants that have wicking properties designed to keep you cool. I've lived in several major cities in the U.S. with very high humidity during the summer, and adult city dwellers just don't wear shorts unless we are going to the gym or playing basketball in the park. Shorts look really out of place at night especially when you may want to go to a nice restaurant, bar, nightclub or theater. I always liked what David Sedaris, American author living in Paris, wrote about people wearing shorts in the city: "Why do they show up dressed like they are about to mow the lawn?". But wear whatever you feel most comfortable in because it's your trip. If the weather gets too cool for shorts, you can always buy yourself a pair of pants and a jacket in Paris or London and consider it a souvenir of your trip.

Thanks everyone for the great tips! Laura thanks so much for that website! I will definitely check it out! I was pretty much planning on taking capris for daytime, dresses and skirts for night or dressier capri's, and maybe one pair of pants. Sounds like I will be in good shape with those. I have a rainjacket that I can pretty much roll up in a ball, so definitely will be taking that. I think you guys have given me a complex about wearing shorts at home now though! haha! Oh and Ceidleh...I LOVE David Sedaris! I'm actually going to see him do a reading next month. He is hysterical! I know what you are referring to with his quote! Well, I am very excited about my trip. My best friend and I both turned 30 this year and this is our present to ourselves. We are actually doing a RS 7 day tour of Paris and then we are taking the Eurostar to London for about 4 days on our own. I have been to Europe once before and spent about 3 days in Paris, but that was in early March and still had to wear winter coat and boots! So, all the feedback has been very helpful! Thanks again!
