According to the government's Daily Mortality Monitoring System, this year's heatwaves have caused 1,149 deaths.

In addition, the extreme heat coincided with Spain's worst month of wildfires on record. Data from the European Forest Fire Information System show that 406,100 hectares of land, roughly 5.5 times the size of Singapore, have been burned.

The fires have claimed four lives and forced over 30,000 people to evacuate. Most evacuees have since returned, but many wildfires remained active as of Sunday.
