In the city of Numata, precipitation occurs throughout the year, and there is no clearly defined dry season. A characteristic feature of the local climate is the high frequency of wet days, although the total monthly precipitation in millimeters remains relatively low. In winter, when temperatures drop below freezing, precipitation primarily falls as snow, while in warmer months, it occurs as rain.

The highest amount of precipitation and the greatest number of wet days occur during the summer period. July is the wettest month, with an average of 8 mm of precipitation and up to 25 wet days. June, August, and September are also characterized by frequent precipitation: there are about 21 wet days in June and September, and 24 days in August, with monthly precipitation around 6 mm.

Winter months, such as January (21 wet days), February (16 days), and December (19 days), bring frequent but usually light snowfalls, given the low temperatures and small total precipitation (3 mm in each of these months). The spring months (March, April, May) and October also have a significant number of wet days (ranging from 16 to 17), with precipitation amounts varying from 4 to 6 mm. November stands out as the month with the fewest wet days—averaging about 13—though the total precipitation (3 mm) is comparable to the winter lows.

When planning a trip to Numata, it’s important to consider the local climate, which is characterized by distinct seasonal changes and a significant amount of precipitation throughout the year. The key to a comfortable trip is a well-thought-out wardrobe based on layering. This will allow you to easily adapt to changing temperatures and be prepared for sudden rain, which is not uncommon here.

Winter months (December to February) in Numata are cold, with average temperatures often below freezing and frequent precipitation that can fall as snow. You will need very warm clothing: a winter jacket or down coat, thermal underwear, warm sweaters (fleece or wool), a hat, scarf, gloves, and waterproof warm boots. In summer (June-August), the weather is warm, with average temperatures rising above +20°C, but this is also the wettest period with many rainy days. We recommend bringing light, breathable clothing made of natural fabrics, sunscreen, a hat, and definitely a light raincoat or a sturdy umbrella.

Spring (March-May) and autumn (September-November) are transitional seasons with changeable weather. It is still quite cool in March and November, while May and September can offer comfortable temperatures. Layered clothing is perfect for these periods: T-shirts, long-sleeved shirts, sweaters or cardigans, and a mid-season jacket, preferably windproof and waterproof. Regardless of the season, comfortable walking shoes are an absolute necessity, as you will likely want to explore the city and its surroundings. And, of course, don’t forget a compact umbrella—it will come in handy in Numata almost year-round.
