The yellow warning issued covers the period between 12:00 on Saturday and 21:00 on Sunday, during which “persistent high maximum temperature values” are expected in the southernmost region of Portugal, the IPMA stated.

The yellow warnings for maximum temperatures are issued in Faro when the thermometers fluctuate between 33 and 37 degrees.

Given the forecast of temperatures that could reach 37 degrees, the State Health Department recommends that the population regularly drink water, wear loose, cool clothing and use sunscreen every two hours.

Exposure to the sun between 11 am and 5 pm is also not recommended, and special care is requested for the elderly, children and chronically ill, who should stay in cooler environments and be protected from the sun, according to health authorities.
