When planning a trip to Oita, it is important to consider the changeable weather and prepare a wardrobe that allows you to feel comfortable at any time of the year. The key principle is layering, as the temperature can change throughout the day, especially during transitional seasons. Indispensable items will be comfortable shoes for walking, as Oita and its surroundings are perfect for exploring on foot. Given that rainy days occur throughout the year, even in months with low total precipitation, a compact umbrella or a light raincoat will be very handy.

In summer, especially from June to August, Oita can be hot and humid, with average temperatures of 22-27°C and frequent rains (up to 20 rainy days in July). Therefore, you should pack light, breathable clothing made of natural fabrics, shorts, t-shirts, sunscreen, and a hat. Do not forget reliable rain protection. In winter (December-February), the weather is significantly cooler, with average temperatures of 5-7°C, but usually without severe frosts. You will need warm items: sweaters, fleece, a medium-weight jacket or coat, trousers, as well as a hat and gloves for colder days or evening walks.

Spring (March-May) and autumn (September-October) in Oita are pleasant transitional periods. In spring, the temperature gradually rises from 10°C to 18.5°C, and in autumn, it decreases from approximately 24°C to 18°C. For these seasons, layered clothing is ideal: t-shirts, long-sleeved shirts, light jumpers, and a versatile jacket (such as a windbreaker). September can still be quite rainy, so an umbrella remains relevant. Overall, this approach to packing will allow you to enjoy your trip to Oita regardless of the whims of the weather.
