noite tropical — "tropical night"
A night when the temperature does not fall below 20 degrees. In Portugal these nights are most common in the Alentejo, the Tagus valley and the eastern Algarve. Doctors consider them more dangerous than the daytime heat: the body cannot cool down overnight, and the strain on the heart builds up day after day.
Where you come across it. IPMA forecasts and news about the heat, health service advice for older people and families with small children.
At home this means airing your rooms not late at night, "when it cools down", but in the early hours of the morning, and keeping the shutters closed during the day. Several tropical nights in a row also dry out the soil — hence the higher fire risk.
