Although the total precipitation during these months is low (around 3 mm), the number of days with precipitation can be significant (up to 20 days in December and 19 in January), indicating frequent but likely light precipitation, such as snow or drizzle.

Precipitation during these periods is moderate but still present. The most notable feature of Nagahama's climate is the pronounced summer wet season, especially in July and August, when the combination of high temperatures and frequent rain creates a rather humid atmosphere.

Packing Tips
When planning a trip to Nagahama, it is important to consider the variable weather and frequent precipitation throughout the year. Regardless of the season, comfortable waterproof shoes will be your best companion for city walks. Be sure to also bring an umbrella or a light waterproof and windproof jacket, as there are many "wet" days in Nagahama (from 12 to 22 per month), even during periods with low total precipitation. The principle of layering your clothes will be your faithful ally in any weather.
In winter (from December to February), Nagahama is quite cold: average temperatures range from 3°C to 5°C, and night temperatures can drop to zero. You will need a full set of warm clothes: thermal underwear, fleece jackets, warm sweaters, a winter jacket (preferably wind- and water-resistant), as well as a hat, gloves, and a scarf. Summer (from June to August) is characterized by warm and humid weather, with average temperatures of 21-27°C. This is also the rainiest season, so pack light, breathable clothing made from natural fabrics, but don't forget a reliable umbrella or a light raincoat. During sunny periods, sunscreen and a hat will come in handy.
In spring (March–May) and autumn (September–November), the weather in Nagahama is more moderate but still changeable. Temperatures in spring gradually rise from 8°C to 17°C, and in autumn, they drop from 23°C to 11°C. During these seasons, the layering principle is especially relevant: T-shirts, long-sleeved shirts, light jumpers or cardigans, and a mid-season jacket that can be easily taken off or put on. Since precipitation is still frequent, don't forget an umbrella or waterproof outerwear to make your journey through Nagahama comfortable.
