What do you want an extreme hot weather or rainy summer days. I heard over the radio that there are places in the U.S. with over 50 degrees celsius temperature at the moment. I remembered the summer in Las Vegas during my 2008 vacation there.
I guess I would rather like rainy summer days than extreme hot summer weather like in Las Vegas. Rainy summer days make the plants and flowers in our garden happy.
During our visit in Paris last summer 2010, it was also raining. As long as you have umbrellas and rain coats with you, there is nothing to be afraid off. Here is the Eiffel tower in Paris during rainy summer days!
