Next week it will be very hot across the whole of mainland Portugal, much as it will be in much of Europe. The Portuguese Institute for Sea and Atmosphere (IPMA) has confirmed forecasts pointing to very high temperatures in Lisbon, around 37 degrees, and above 40 in inland regions, particularly the Alentejo.
The official designation of a “heatwave” can only be confirmed later, as it requires at least six consecutive days with temperatures at least five degrees above the average of the past 30 years, within a 15-day window.
