About Estrela in September
Estrela benefits from the substantial cooling effect of the Jardim da Estrela, one of Lisbon's largest parks, which creates a measurable green island effect reducing ambient temperatures by 2–3°C on summer days. Its elevated western position catches Atlantic air masses early, and the basilica's dome acts as a local wind deflector creating sheltered pockets on its leeward side.
