The city of Kochi, located in Japan, is characterized by a humid subtropical climate.

Overall, the weather offers variety, ranging from cool winters to hot and humid summers.

Winters in Kochi (from December to February) are quite mild, with average temperatures around 4-6°C, and this is the driest period of the year. Spring (from March to May) brings gradual warming, with average temperatures rising from 9°C to 17°C, while rainfall increases.

Autumn (from September to November) starts off warm, with temperatures around 23°C, and gradually becomes cooler, approaching 12°C in November, while precipitation also decreases.

One of the key features of Kochi's climate is the pronounced rainy season, which falls during the summer months. The highest amount of rainfall and rainy days is observed from June to September, peaking in July, when about 14 mm of precipitation falls and there are up to 24 rainy days. Therefore, when planning a trip, it is worth considering this factor, especially if you prefer drier weather for outdoor activities.

When planning a trip to Kochi, it is important to consider the changeable weather throughout the year so that your luggage is packed correctly. The key principle is layering your clothes, as this will allow you to easily adapt to temperature changes. Regardless of the season, comfortable walking shoes are your main companion, as Kochi and its surroundings are perfect for long walks. Do not forget a small backpack for daily excursions, where you can put a water bottle, a map, and other small items.

In winter (from December to February), it is quite cool in Kochi, with the average temperature ranging from 4.5°C to 6°C, and nightly lows can drop almost to zero. You will need warm items: sweaters, fleece tops, a warm jacket (preferably windproof and waterproof, as precipitation is possible), a hat, gloves, and a scarf. Spring (from March to May) and autumn (from September to November) are characterized by milder weather but still require foresight. During the day, the temperature can be comfortable (from 9.6°C to 17.4°C in spring and from 11.9°C to 23.1°C in autumn), but evenings can be cool. A light jacket, cardigan, jeans, or thick trousers will be appropriate.

Be sure to take a reliable umbrella or a quality raincoat with you. Sunscreen, a hat, and sunglasses are also necessary for sun protection on clear days. Given the high humidity and frequent rains, quick-drying clothing can be very practical.
