In the city of Belleville, precipitation is distributed quite evenly throughout the year, with no distinct rainy or dry season. The key differences between months lie not so much in the total volume of precipitation, which remains consistently low, but in the frequency of days with precipitation. This creates a predictable but moderately humid climate for most of the year.

The wettest period in terms of precipitation frequency is spring. May stands out as the month with the highest number of rainy days — averaging about 14. March and April are also quite wet, with 12-13 days of precipitation. In summer, especially in July and August, rain also falls frequently. The driest months of the year are considered to be September and November, when the number of days with precipitation drops to 7-8.

The nature of precipitation changes depending on the season. In winter, especially in January and February, when average minimum temperatures drop below freezing, precipitation often falls as snow. During the rest of the year, from spring to autumn, it is generally rain. Given the small monthly amount of precipitation (3-4 mm in the wettest months), it is most often light or moderate rain rather than heavy downpours.

When planning a trip to Belleville, it is important to consider the distinct change of seasons so that your wardrobe matches the weather. Summer here is quite hot and humid; the average temperature in July and August reaches +25-27°C, and daytime highs often exceed +30°C. For a summer trip, pack light, breathable clothing made of natural fabrics, shorts, t-shirts, and sandals. Do not forget sunscreen, a hat, and sunglasses. Despite the low level of precipitation, rainy days happen in summer, so a compact umbrella or a light waterproof windbreaker may come in handy.

Winters in Belleville are cold, with average temperatures around zero degrees and night frosts. If your trip falls between December and February, be sure to bring a warm winter jacket, sweaters, a hat, gloves, and a scarf. For the transitional seasons — spring and autumn — the principle of layering works best. The weather at this time can be unpredictable, with cool mornings and warm days. Jeans, long-sleeved t-shirts, light jumpers, and a mid-season jacket will be the ideal choice. Regardless of the time of year, comfortable walking shoes are an absolute necessity for exploring the city comfortably.
