When planning a trip to Zhushan, it is important to consider the local climate, which is characterized by warm weather year-round and significant rainfall, especially from May to September. Regardless of the season, you will need a light waterproof jacket or a sturdy umbrella, as rain is common here. Comfortable walking shoes, preferably water-resistant, will also be indispensable for exploring the city and its surroundings. Don't forget sunscreen and a hat, especially if your trip falls during the summer months.

During the summer period (May to September), when average temperatures reach 25–26°C and the number of rainy days is at its peak, opt for light, breathable clothing made of natural fabrics. Shorts, T-shirts, sundresses, and sandals will be the most comfortable. In the cooler months (December to February), when the average temperature hovers around 16–17°C and the minimum can drop to 12–14°C, it is worth bringing warmer clothes. The principle of layering is very useful here: T-shirts or long-sleeves, a fleece or a light sweater, along with a windbreaker or a light jacket will keep you comfortable throughout the day as you adapt to potential weather changes. Long trousers or jeans are also appropriate.

Given the high humidity and frequent rainfall, especially in summer, quick-drying clothing can be quite practical. A small backpack for day trips to carry an umbrella, water bottle, and other essentials will also be useful. At any time of year, it's worth having insect repellent on hand, especially if you plan on nature walks. An adapter for electrical appliances, if different from those used in Taiwan, will also come in handy.
