Zhongshan in May

Spring and fall are your golden windows - March through May and September through November. Temperatures hover around 15-25°C (59-77°F), perfect for wandering hutongs without melting or freezing. Avoid summer unless you enjoy 35°C heat and humidity that makes your clothes stick to your skin. Winter can be magical with snow on traditional rooftops, but temperatures drop to -10°C (14°F). The air quality is generally better in these shoulder seasons too. Here's an insider tip: visit during Chinese New Year (late January or February) if you want to see the neighborhood come alive with red lanterns and family celebrations. Just book accommodation way in advance - locals return home and everything gets busy.
