Nagoya experiences noticeable seasonal fluctuations in the amount of precipitation throughout the year. The wettest period is summer, especially mid-summer, while the winter months are characterized by significantly less rain.

When planning a trip to Nagoya, it is important to select your wardrobe correctly, considering the distinct change of seasons. Regardless of the time of year, comfortable shoes for long walks will become your indispensable companion. It is also worth adhering to the principle of layering in clothing — this will allow you to easily adapt to temperature changes throughout the day and between indoors and outdoors, which is particularly relevant for the climate of Japan.

If your journey falls in summer (June-August), be prepared for hot and humid weather. You should pack light, breathable clothing made from natural fabrics, shorts, t-shirts, a hat, and sunscreen. Given that July is the month with the highest amount of precipitation and rainy days, and June and August are also quite wet, a reliable umbrella or a light raincoat will be absolutely essential. In winter (December-February), Nagoya is cool, with average temperatures holding around +5°C, and night temperatures can approach zero. Therefore, you will need warm clothes: sweaters, a warm jacket, a hat, a scarf, and gloves. Despite the cool weather, winter here is relatively dry.

Spring (March-May) and autumn (September-November) in Nagoya delight with more comfortable temperatures. For these seasons, a mid-season jacket or trench coat, and several sweaters or fleece tops that can be removed or put on as needed, will be ideal. Although precipitation during these periods is moderate, it is still worth having an umbrella with you, especially in March, May, September, and October, when the number of rainy days can be significant. In general, a well-thought-out wardrobe will make your stay in Nagoya pleasant in any weather.
