Planning a trip or a stroll through the city of Uonuma? Here you will find the latest weather information, including detailed forecasts and visual charts to help you plan your day perfectly.

The climate in the city of Uonuma, located in Japan, can be characterized as temperate, with four distinct seasons. Uonuma is marked by significant temperature fluctuations throughout the year, ranging from cold winters to warm and occasionally hot summers. This indicates a notable influence of continental air masses, which provides a diverse range of weather conditions.

Winter (December–February) in Uonuma is cold, with average temperatures often dropping to zero and below, especially in January (average temperature -0.7°C). During this period, the highest number of days with precipitation is observed (26–27 days in December and January), which, given the temperature, often results in snowfall. Spring (March–May) and autumn (September–November) are transitional periods with gradual warming and cooling, respectively. Summer (June–August) is warm, with peak temperatures in July and August, when average values reach 24–25°C. The hottest month is August, with an average temperature of 25.2°C.

An interesting feature of the weather in Uonuma is the high number of "wet days" throughout the year, even with relatively low monthly precipitation totals in millimeters (ranging from 5 to 9 mm). This suggests frequent but not always heavy precipitation, whether rain or snow, depending on the season. For example, even during the driest months in terms of precipitation volume (March–May, April), there are still 15–19 wet days.

The weather in Uonuma demonstrates pronounced seasonal temperature fluctuations throughout the year. The coldest month is January, when the average temperature is -0.7°C, and minimum night temperatures can drop to -3.9°C. Daytime highs in January barely reach +2.5°C. In contrast, August brings the hottest weather: the average temperature rises to +25.2°C, and daytime peaks can reach +29.1°C, while nights remain warm with minimum temperatures around +21.4°C. Thus, the annual temperature range in Uonuma is quite significant.

The summer months, from June to August, are characterized by increasing heat. June begins with a moderate average temperature of +19.5°C (ranging from +15.1°C to +23.9°C), but by July it becomes significantly hotter, with an average temperature of +24.0°C (from +20.2°C to +27.8°C). August, as mentioned, is the peak of summer. Given the high number of days with precipitation in the summer months (19–23 days), the weather can feel warm and humid, bordering on sultry. The difference between day and night temperatures in summer averages 7–9°C, providing some nocturnal cooling.

Winter in Uonuma, spanning from December to February, is cold and snowy. In December, the average temperature stays around +1.6°C (ranging from -1.8°C to +5.1°C). January and February are the frostiest months, with average temperatures of -0.7°C and +0.1°C respectively, and frequent night frosts down to -3.5°C and below. Daytime temperatures in the height of winter rarely rise significantly above freezing. The high number of days with precipitation (21–27 days) in these months indicates heavy snowfall. Daily temperature fluctuations in winter are about 6–7°C.

In the city of Uonuma, precipitation occurs quite frequently throughout the year, though its intensity and character change depending on the season. Winter months, especially January (27 wet days, 7 mm of precipitation) and December (26 wet days, 8 mm), are characterized by a high frequency of precipitation. Given the low average temperatures during this period (January: -0.7°C, December: 1.6°C), precipitation primarily falls as snow. February also brings a significant number of snowy days (21 days) and 6 mm of precipitation.

In spring, the number of wet days and the total volume of precipitation decrease slightly. April is the month with the fewest wet days (averaging 15) and receives 5 mm of precipitation. March and May are also relatively "dry" months in terms of volume, with 5 mm each and 19 and 16 wet days respectively. During this time of year, precipitation falls mainly as rain. In the summer, both the frequency and intensity of precipitation increase. July stands out as the wettest month by volume (9 mm) and has a high number of rainy days (23 days). August also experiences frequent rain (22 days), bringing 6 mm of precipitation.

The autumn months—September, October, and November—show a moderate amount of precipitation (6 mm each) and a stable number of wet days (about 18 days per month). Thus, there is no pronounced dry season in Uonuma. The lowest amount of precipitation falls in the spring (March, April, May), while winter (especially December and January in terms of frequency) and mid-summer (July in terms of volume) are the periods with the most precipitation.

When planning a trip to Uonuma, it is important to take into account the significant seasonal weather variations. Winter months (December–February) are cold here, with average temperatures around 0°C and frequent precipitation, which will most likely be snow at these temperatures. Therefore, during this period, you will need very warm clothing: thermal layers, an insulated waterproof jacket, a hat, gloves, a scarf, and waterproof winter boots. Given the high number of days with precipitation (21–27 days per month), reliable moisture protection is essential.

Spring (March–May) and autumn (September–November) are transitional seasons with moderate temperatures but still a high probability of precipitation (15–19 days with precipitation per month). It can be quite chilly in March and November, so it is worth bringing a jacket, sweater, and closed-toe shoes. In April–May and September–October, the weather becomes warmer, but the principle of layering remains relevant: a light jacket or windbreaker, a jumper, and comfortable trousers. In summer (June–August), Uonuma is warm, with average temperatures reaching 24–25°C. However, the number of days with precipitation remains high even at this time of year (19–23 days). Therefore, in addition to light summer clothing made of natural fabrics, shorts, t-shirts, and sandals, don't forget to pack a light waterproof jacket or raincoat.

Regardless of the time of year, be sure to bring comfortable walking shoes for your trip to Uonuma, as you will surely want to explore the surroundings. An umbrella or raincoat will be your faithful companions almost all year round due to frequent precipitation. In the summer months, sunscreen and a hat will also be useful for sun protection on clear days. Layering your clothing is an excellent strategy for Uonuma, allowing you to easily adapt to changing weather conditions throughout the day.
