About Lumiar in September
Lumiar's position on Lisbon's northern plateau, away from the Tagus moderating influence, gives it the city's greatest diurnal temperature range — summer nights are notably cooler than downtown while afternoon peaks match or exceed riverside readings. The neighborhood's lower building density and proximity to extensive green spaces around the Lisbon University campus allow cold air to settle freely on calm winter nights.
