The climate of Williston can be described as sharply continental, which implies significant contrasts between seasons. The weather here is far from monotonous: travellers can expect a distinct change of seasons. Winter in this region of the United States is generally cold and frosty, while summer brings real warmth and an abundance of sunlight.

The warmest period falls in July and August, when the average temperature hovers around +22°C, and during the day the air often warms up to +29°C. This is the ideal time for outdoor activities. Winter months, especially January and February, require thorough preparation and warm clothing, as temperatures consistently drop below zero, reaching an average of -8...-9°C, and nights can be even colder.

The transitional seasons — spring and autumn — pass quite dynamically. While March still retains winter chill, May already delights with a comfortable +13°C. September gifts mild weather before the cold sets in, but by November, freezing temperatures return. Precipitation falls moderately throughout the year, so extremely wet seasons are not observed here.

The climate in Williston is characterised by distinct seasonality and a significant temperature amplitude throughout the year. Winters here are truly severe and frosty, which is typical for the northern regions of the USA. According to statistics, the coldest month is February, when the average temperature drops to -9.1°C, and night-time figures can reach -14.4°C. January and December are also characterised by stable sub-zero temperatures, so travellers planning a visit at this time need high-quality warm clothing and thermal underwear.

Summer brings a radical change in weather, delighting with warmth and comfortable conditions for walking. The hottest period falls in July, when the average temperature is about 22.7°C, and daytime maximums often rise to 29.4°C. June and August also offer pleasant weather with daytime temperatures in the range of 25–28°C. This time of year is ideal for active leisure, as despite high daytime figures, exhausting heat is a rare phenomenon here.

An important feature of the local climate is noticeable diurnal temperature fluctuations. Even in the warmest summer months, the difference between daytime heat and night-time coolness can be more than 13 degrees: after a hot July day (about +29°C), the night can bring freshness with a temperature of about +16°C. In transitional seasons, for example in April or October, these shifts are felt even more strongly, when the air warms up to positive values during the day, but frosts are possible at night. Therefore, the principle of layering in clothing is relevant for Williston all year round.

The climate of Williston is characterised by clear seasonality, and the nature of precipitation depends directly on air temperature. In the winter months, from November to March, when average thermometer readings drop significantly below zero, precipitation falls mainly as snow. Although the total volume of winter moisture is small, persistent frosts contribute to the preservation of snow cover throughout the cold season.

The most active period for precipitation falls in late spring and early summer. The "wettest" month of the year is May, when an average of about 10 rainy days is recorded. In June, the frequency of precipitation remains high (about 8 days), but with the arrival of real summer warmth, prolonged rains are often replaced by short-term showers that quickly refresh the city.

The second half of summer and the beginning of autumn are generally more stable. In August and September, the number of days with precipitation decreases to 5–7 per month. According to statistics, the driest period of the year is the end of winter: in February, inclement weather happens least often — on average, only 4 days per month.

Winter in Williston can be quite severe, so if your trip is planned for the period from December to February, it is worth preparing thoroughly for the cold. Since the temperature often drops significantly below zero (down to -14°C), a warm windproof down jacket or parka will become your main companions. Be sure to take high-quality thermal underwear, insulated boots with thick soles, as well as a hat, scarf, and gloves to protect yourself from the frosty air.

Summer here, on the contrary, delights with warmth: in July and August, the air often warms up to +29°C. For this season, light clothing made of natural fabrics is ideal, as well as sunglasses and cream for protection from the active sun. Spring and autumn are distinguished by variability: March and November can still be frosty, while May and September are comfortable and mild. In the transitional seasons, it is best to stick to the principle of layering, combining T-shirts with jumpers and light jackets to easily adapt to temperature changes.

Regardless of the time of year, put comfortable shoes in your suitcase for long walks, as you will surely want to explore the surroundings. Although the level of precipitation is generally low, in May and June the number of wet days increases slightly, so a compact umbrella or a light raincoat will not take up much space in your luggage but may prove very useful.
