When planning a trip to Hsinchu, it is important to choose your wardrobe wisely, considering the local subtropical climate with warm weather and frequent, though not always heavy, rainfall throughout the year. In summer, from May to September, when temperatures average 25-28°C and humidity is high, opt for light and breathable clothing made from natural fabrics: T-shirts, shorts, and dresses. Be sure to pack sunscreen with a high SPF, a hat, and sunglasses. Despite the warmth, be prepared for short rains, especially in August when the number of rainy days is at its highest, so a compact umbrella or a light raincoat will come in very handy.

In the cooler months, from December to February, the average temperature drops to 15-17°C. During this time, light jackets—preferably windproof, as Hsinchu is known for its winds—as well as sweaters, jeans, or trousers will be useful. For the shoulder seasons (March-April and October-November), the climate is comfortable but changeable. Layering is the ideal principle here: combine T-shirts with cardigans, light sweaters, or windbreakers. Regardless of the season, comfortable shoes for long walks are an absolute must, as is a small umbrella, given the consistent number of rainy days throughout the year.
