What you should do

  • Watch the feels-like temperature, not just the thermometer; humidity makes heat far more dangerous.
  • Drink water regularly, before you feel thirsty, and avoid alcohol and sugary drinks.
  • Stay in shade or a cool room during the hottest hours, roughly 11h to 16h; never leave anyone in a parked car.
  • Check on elderly neighbors, young children and outdoor workers; they are most at risk.
  • Always follow your national meteorological service and local civil defense. Their warnings override anything on this page.
