The thermometer hits 36 degrees this Thursday in Madrid

The alert also affects other areas of the region, although the expected temperatures vary depending on altitude and location. The heat will be most intense in the afternoon, when asphalt, building facades, and less ventilated stations have accumulated several hours of sun exposure.

In the capital, skies are expected to be mostly clear and the maximum temperature will be close to 36 degrees. Minimum temperatures will remain high, making it a difficult night for those living without air conditioning or with poor ventilation.

The heatwave will be especially noticeable in neighbourhoods with few trees and large paved areas. Walking, waiting for the bus, or making long journeys between two and seven in the afternoon will be more uncomfortable, especially for older people, children, and those who work outdoors.

Metro and Cercanías offer an alternative to long walks, although entrances, platforms, and transfers can also become hot spots. It's advisable to carry water, avoid staying in the sun for long periods, and allow extra time to travel without rushing.

Parks and green spaces may offer slightly more bearable temperatures, but not all areas have the same amount of shade in the afternoon. Intense physical activity should be scheduled for early in the morning or late in the day.

Health authorities recommend staying hydrated, avoiding alcohol, wearing light clothing, and paying attention to symptoms such as dizziness, headache, weakness, or confusion. If symptoms worsen quickly, it's important to get out of the heat and seek help.

The afternoon will see quieter streets during the hottest hours, and terraces will become busier once the sun goes down. Real relief will take time to arrive: even after the warning ends, buildings and pavements will continue to release accumulated heat well into the night.
