When planning a trip to Nanjo, it's important to consider its subtropical climate with warm weather year-round and a notable number of rainy days. Regardless of the season, you'll need comfortable walking shoes, as the city and its surroundings are perfect for exploring. Given that rain occurs quite frequently, especially from May to September and in December, a lightweight waterproof jacket or a compact umbrella will be your reliable companions. Sunscreen and a hat will also come in handy, especially during the summer months when temperatures peak.

From December to March, the average temperature hovers around 18-20°C. During this period, it's worth bringing light jackets, sweaters, or fleece hoodies, as well as T-shirts and long-sleeved shirts. Layering will allow you to feel comfortable both indoors and outdoors. From April to November, it becomes significantly warmer. In summer, especially from June to September, when the average temperature stays around 26-28°C, your main wardrobe should consist of light, breathable clothing: T-shirts, shorts, and sundresses made of natural fabrics.
