Therefore, travellers planning a trip to Toyama should be prepared for changeable weather and frequent precipitation, regardless of the season. In summer, expect warmth and high humidity, while in winter, expect cool weather with possible snowfall.

The winter months, especially January and December, are characterized by the highest frequency of precipitation – approximately 25 wet days in each.

Travellers should be prepared for precipitation at almost any time of the year.

When planning a trip to Toyama, it is important to be prepared for its humid climate. The city is distinguished by frequent precipitation throughout the year – averaging from 14 to 25 rainy days per month! Therefore, a waterproof jacket or a high-quality umbrella will become your faithful companions. It is also highly recommended to bring comfortable waterproof shoes, as you will surely want to explore the city on foot. Dressing in layers is advisable – this will allow you to easily adapt to weather changes throughout the day.

In winter (December to February), Toyama is cold, with average temperatures staying in the 1-4°C range, often dropping below freezing, and precipitation frequently falls as snow.

Summer (June to August), on the other hand, is warm and very humid, with average temperatures of 20-26°C. For this season, choose light, breathable clothing made from natural fabrics, not forgetting sunscreen, a head covering, and light rain protection, as downpours, especially in July and August, are not uncommon.
