Insider timing tips

•While summer (July-August) offers the warmest weather, it also brings peak crowds and prices, and the city can be uncomfortably hot.
•The shoulder seasons (April-May and September-October) offer a sweet spot with pleasant weather, fewer crowds than summer, and more reasonable prices.
•Lisbon's annual 'Festas de Lisboa' in June, celebrating Saint Anthony, transform the Alfama and Bairro Alto districts into vibrant street parties, making it a unique cultural experience.
•Winter months (December-February) are the cheapest and least crowded, but come with a high probability of rain and limited daylight, making outdoor activities less appealing.
•The Atlantic coast offers cooler temperatures and sea breezes, providing relief from inland heat, especially in July and August.
