Spring (March to May): Spring is an ideal time to visit Porto, as the weather becomes warmer and the city’s gardens and parks bloom with vibrant colors. The temperatures range between 55°F (13°C) and 68°F (20°C), making it perfect for outdoor sightseeing and exploring the city’s architectural gems. Spring also sees fewer tourists, offering a more authentic and less crowded experience.

Summer (June to August): Summers in Porto are warm and sunny, with temperatures ranging from 60°F (16°C) to 77°F (25°C). This season attracts the highest number of tourists, so expect the city’s attractions to be more crowded. On the bright side, numerous festivals and events, like the São João Festival, take place during this time, adding a unique charm and energy to the city.

Autumn (September to November): Autumn is another lovely season to visit Porto, as the weather remains pleasant, with temperatures between 50°F (10°C) and 72°F (22°C). The city is less crowded than in summer, and the beautiful fall foliage creates a stunning backdrop for photographs. Be prepared for occasional rain showers, so pack an umbrella and waterproof shoes.

Winter (December to February): Winters in Porto are mild compared to other European cities, with temperatures ranging from 45°F (7°C) to 57°F (14°C). Although the city experiences more rainfall during this season, you’ll find fewer tourists and lower accommodation rates. Winter can be a great time to enjoy Porto’s cozy cafes, museums, and wine cellars while sipping a warm cup of coffee or a glass of Port wine.

In summary, the best time to visit Porto depends on your preferences and priorities. If you prefer pleasant weather and fewer crowds, spring and autumn are ideal. However, if you’re keen on attending festivals and don’t mind the tourist crowds, summer is your best bet.
