Alcântara, Lisbon, Portugal
About Alcântara in September
Alcântara sits in a low valley between the hills of Estrela and Ajuda, creating a natural drainage channel where cool nighttime air pools, resulting in Lisbon's most frequent valley fog occurrences. The neighborhood's industrial heritage of warehouses and rail infrastructure creates significant thermal mass that retains heat, contrasting with the river-cooled air just meters away at the dockside.
