Regardless of the season, bring clothes that are easy to combine using the layering principle. The weather in Sintra can be changeable, especially due to the influence of the Atlantic and the city's elevated location, so a light jacket or sweater will come in handy even on a summer evening. Don't forget sunscreen, as the sun can be active even on cool days.

If your trip falls during the summer months (from June to August), when the average temperature hovers around 18-20°C and there is practically no precipitation, light items like T-shirts, shorts, and sundresses will form the basis of your wardrobe. However, given the potential evening breeze or temperature drops in different parts of the city (for example, by the ocean or on the hilltops where the palaces are located), bring a light sweater or windbreaker. Sunglasses and a hat will also be very useful, as summer in Sintra is sunny and dry.

For a trip to Sintra during the cooler and wetter time of year, roughly from October to April, when average temperatures are between 12-18°C and the number of rainy days increases (up to 9-11 days in some months, especially November, December, and April), you should prepare more thoroughly. You will need warm sweaters or fleece jackets, trousers, as well as a waterproof jacket or raincoat and an umbrella. Layering is particularly important here to feel comfortable both indoors and outdoors, where it can be windy and damp.
