The city is not cooling down. IPMA‘s yellow warning for the Lisboa district—valid until 18:00 on 28 July 2026—flags what residents already feel: persistent high maximum temperatures, the kind that compound day after day rather than spike and retreat. This is not record-breaking drama; it is the slow grind of late July.
Shift errands to before 10:00 or after 18:00, drink water before you are thirsty, and let the river-facing esplanadas wait until golden hour. The shade at Jardim da Estrela earns its keep on days like these.
