One should avoid going to Europe this year because of extreme heat waves. No countries spared of it, including Switzerland and Austria all ice melted from Alps. Temperature was touching 31-35 degree very hot and humid. Not possible to visit any place in day time as it was similar to weather back in India. Enjoyed only mornings and sunsets. People there are getting fed up with extreme heat We noticed water jets were sprayed in public areas to avoid heat stroke very unusual to there place. Switzerland was also very warm even on glacier at zermatt we didn’t required any warm clothes. See how Matterhorn in Zermatt, Switzerland looks bare which usually remains ice capped through the year So better not to go to Europe this year. If you are already booked pack enough sunscreen and only cotton wears
