What to do in Lisbon in septiembre
The editorial plan
Why Lisbon in septiembre
Festa do Avante! September 4-6 at Quinta da Atalaia (Seixal) — 50th anniversary with 60+ concerts, reached by ferry across the Tagus.
Opera season returns to Teatro Nacional de São Carlos — the 2026/27 opera and ballet program opens with full-season subscriptions on sale.
Sweet-spot 20-27°C without July's heat spikes — equinox golden light over the Tagus from Castelo and Senhora do Monte miradouros.
Lisbon is worth visiting other months too
