Spring (April-May): Pleasant temperatures (15-25°C), blooming flowers, cherry blossoms in parks, and comfortable outdoor exploration. Air quality generally improves. This is peak tourist season with higher prices and crowds.
Autumn (September-November): Clear skies, mild temperatures (10-20°C), and vibrant autumn foliage. Excellent visibility for sightseeing and photography. Comfortable weather for outdoor activities. Generally considered the best season.
Summer (June-August): Hot and humid (25-35°C+), occasional rain, and high pollution levels. Monsoon season brings afternoon thunderstorms. Despite heat, it's popular with families on vacation. Avoid midday outdoor activities.
Winter (December-February): Cold (−5 to 5°C), dry, and occasionally snowy. Beautiful clear skies but requires heavy clothing. Heating indoors is excellent. Chinese New Year festivities create vibrant cultural experiences. Fewer tourists mean shorter queues.
Best Overall: September-October offers ideal weather, clear air, and comfortable conditions for all outdoor activities.
