Europe's Sunniest Capital
Lisbon is Europe's sunniest capital, and its Mediterranean-meets-Atlantic climate rewards visitors in almost every month of the year.
Spring & Summer — Jacarandas and Festas
Spring (March–May) is the consensus best season: mild 10–23°C temperatures, the first beach days at Cascais from late May, and the jacaranda trees blooming in purple along Avenida Dom Carlos I and Praça do Príncipe Real in mid-to-late May. Summer (June–August) is when the city reaches peak energy — Festas de Lisboa runs all month in June, peaking with Santo António on June 12–13 when Alfama turns into an open-air sardine-and-fado party, NOS Alive delivers Portugal's biggest music festival in early July, and Jazz em Agosto at the Gulbenkian gardens anchors the cultural calendar through August. The famous Lisbon heat is moderated by Atlantic breezes and low humidity.
Autumn & Winter — Beaches and Mild Days
Autumn (September–November) is the smart traveller's season: September delivers the best beach weather of the year (sea temperatures peak at 20–21°C), October brings the grape harvest across the Setúbal peninsula, and November hosts Web Summit — the world's largest tech conference — along with the São Martinho chestnut tradition on November 11. Winter (December–February) is one of Europe's mildest capital-city experiences: 8–16°C averages, fewer tourists, one of Southern Europe's best Christmas illuminations along Avenida da Liberdade and Rossio, the Praça do Comércio NYE fireworks, Carnival in February, and the lowest hotel rates of the year outside the NYE spike.
