The first major heat wave of the summer has hit Europe, exposing millions of people to record-breaking temperatures, closing tourist attractions, and fueling wildfires due to dry conditions. 

France, Greece, Italy, Portugal, and Spain are among the countries affected by the extreme temperatures. Spain recorded its hottest June in over a century, and London’s St James’s Park recorded its hottest day of the year at 94 degrees Fahrenheit on Tuesday. France closed at least 1,300 schools due to the extreme heat.
