Several European regions had their highest temperatures on the last day of June, as a heatwave continues into July.

The Mediterranean Sea was up to 6 degrees Celsius warmer than usual for the time of year, hitting a record of as much as 30 C (86 F) in Spain's Balearic Sea as a heat dome trapped hot air above Europe, the country's Aemet weather forecaster said.

Health warnings remained in effect in several European countries. The worst was felt in southern Europe while punishing temperatures were forecast to reach 40 degrees Celsius (104 degrees Fahrenheit).
