What is the weather - Italy and Switzerland Jun till mid Jul

What is the degree celcius - when u said hot or very hot. Italy and Swiss

90° Fahrenheit = about 32° Celsius. That would be hot. I don't know what was meant by 'cooler' in Switzerland in the above reply, but I consider summer 'cool' to be about 60°F, which would be about 16°C. The charts on this page might help: http://tours.ricksteves.com/tours/pages/weather.cfm They're all in Fahrenheit because they were created for a predominantly American audience that easily understands Fahrenheit. You can find several temperature conversion calculators on the Internet.

Temperatures in Switzerland can also vary considerably between the high Alpine region of the south and the lower moutains and hills of the north. Where will you be in Switzerland?
