How does humidity affect the weather??

Well, Arizona is warm and dry most times right? Paris in November is likely to be neither, but people like Kent( being from Oregon) and me( being from British Columbia) most likely won't "feel" the cold the way you will, so, my advice is bring things that will help you feel warm, I personally do find the "damp" makes the cold feel "colder" .
Bring a small umbrella( the purse size is good) , gloves ( not snow mitts, just some light gloves,LOL) a good jacket/coat( either a raincoat with a warm zipout lining, or I myself bring a wool "car" coat, and shoes that don't let your feet get soaking wet too easily. Museums can feel hot and stuffy if you don't have layers to remove , but walking along the Seine can feel very cold if you don't have a good coat, so you are going to have to just do your best and have fun!

Scarves are very popular in Europe, plus they keep your neck warm. Umbrellas and scarves are easy to buy when you get there, if you choose to do so.

Hi Angela.. It's called "the dew factor" and is alot like your "heat index" the actual temp might say 50 degrees but if the humidity is high.. it will feel several degrees cooler..The wind plays a factor as well.. blows all that cooled air right smack dab down your neck!!! socks.. bring lots of socks.. If your feet are cold.. you can feel absolutley miserable. gloves help a lot too. and remember 90 % of your body heat leaves from your head so a hat might be a good idea as well.. Bon voyage !!

Here on the Pacific coast, I feel the "cold" way more than lower temperatures inland. It chills me to the bone, so you will probably feel the cold even more than I! I find mini knit gloves perfect to tuck into my pocket and camisoles really help keep in the body warmth.

Thank you all so much for your help! I actually had to buy a jacket for this trip if that gives you any idea of what the weather is like here in Tucson, lol. Thanks again!

Angela , now that is just bragging,LOL, going to Paris and living in a warm climate!LOL

Just to give you and idea of the effect of humidty,
We live on the East coast half way between NY and Washington DC. We have more humidity in the air and the winters seems very cold. My husband loves to ski. When we go to Colorado there is less humidity in the air in the winter and even though it might be the same temp as at home it always feel less cold there. I'm glad you bought a coat. We also get our temps at home on the weather in "Wind Chill factor" versus real temp. The wind will also makes it feel colder. Where I just retired from teachng if the temp or "wind chill" fall below a certain degree, they don't send the kids outside for outdoor recess.

Yep Pat, I guess I shouldn't mention then that it's a beautiful and sunny 87 degrees F here today, lol.

Thanks again for the help!

It was even better in Denver, sunny and 74.

As a fellow desert dweller, may I just mention that it takes longer - much longer- for clothes to dry in a humid climate. Clothes that dry at home in a few hours have taken two days in Paris. So, pack really, really quick drying clothes or make other laundry arrangements.

Angela, in general, humidity makes the hot hotter and the cold colder. Where I live it gets as hot as the south and as humid (although not for as long of a time). And when I was in Venice the high humidity in the winter made the cold feel bone-chilling. Basically the humidity works its way into your bone marrow and you can't shake it for like a day.

My advice is to layer if you're worried about the cold and humidity. But 50 degrees for highs should be ok. The humidity will make it feel colder.

Most important, bring a light parka that is wind and rain proof and has a hood. You don't need a heavy parka because you'll get warmth from layers. I usually pack all summer weight clothing including light sweaters and layer as needed. If it's relatively nice you have choices that don't make your suitcase bulge. If it's freezing, you can wear most of it. Keep your coat with you. I've had days in London that looked beautiful. I left my coat at the hotel and regretted it later when I was running through pouring rain. Umbrellas aren't as good because the travel ones can't take any real weather.
