When planning a trip to Zhongshan, it is important to consider its humid subtropical climate with distinct seasons so that your luggage is as functional as possible. From May to September, hot and humid weather prevails here, with frequent rains, especially in June and August. Therefore, during this period, the foundation of your wardrobe should consist of light, breathable fabrics, such as cotton or linen. Do not forget an umbrella or a light raincoat, as well as sunscreen, a hat, and sunglasses for protection against the active sun. Comfortable waterproof or quick-drying shoes will also be very handy.

Winter in Zhongshan, from December to February, is quite mild, with average temperatures around 16-17°C and significantly less rainfall. For this time of year, the layering principle is ideal: take light sweaters, cardigans, long-sleeved t-shirts, and one warmer jacket or windbreaker that can be taken off in a warm room or on a sunny day. Spring (March-April) and Autumn (October-November) are pleasant transitional seasons with comfortable temperatures, but the chance of rain still remains, especially in spring, so a light jacket and an umbrella will not be superfluous.

Regardless of the time of year, comfortable walking shoes are an absolute necessity, as you will surely want to explore the city. Also, think about a small backpack for day trips, where you can put a bottle of water, a map, and other small items. If you plan to visit temples or official institutions, it is worth taking clothes that cover your shoulders and knees. And, of course, do not forget an adapter for your electronic devices if one is required.
