Winters, conversely, are cool, with an average January temperature of 2.4°C; during this period, night frosts are not uncommon when the temperature drops below freezing.

Regarding precipitation, according to the provided data, it is distributed relatively evenly throughout the year, although the monthly amount is indicated as very low, fluctuating only from 2 to 4 mm. The number of days with precipitation ranges from 7 to 13 per month. It is important to note that such millimetre-equivalent precipitation figures are atypically low for the Roanoke region, which usually receives a moderate amount of rainfall year-round. The provided figures may reflect a specific, possibly abnormally dry period, or specifics of the data collection methodology, and may not correspond to long-term climatic norms for this area.

The temperature regime in Roanoke demonstrates a distinct change of seasons. The hottest month is July, when the average air temperature is 24.7°C, daily highs often reach 29.9°C, and nights remain warm with an average low of 19.4°C. In contrast, January is the coldest month with an average temperature of 2.4°C, night frosts down to -1.8°C, and daytime temperatures usually not exceeding 6.7°C. These two months set the main temperature boundaries of the year in the city.

The summer period, besides July, includes a warm June with an average temperature of 21.8°C (from 16.5°C at night to 27.0°C during the day) and a comfortable August with its 23.5°C (from 18.5°C to 28.5°C). Daily temperature fluctuations in summer are about 10-10.5°C, providing pleasant coolness in the evenings. In winter, besides January, December brings an average temperature of 4.6°C (from 0.2°C to 8.9°C), and February is slightly warmer at 5.9°C (from 0.9°C to 10.9°C). Winter daily temperature drops are also noticeable, varying from 8.5°C to 10°C, thanks to which daytime can be relatively mild even after a cool night.

Transitional seasons in Roanoke offer particularly pleasant weather for visiting. In spring, the temperature gradually rises: in March, the average is 8.7°C (minimum 3.1°C, maximum 14.3°C), in April it is already 13.2°C (minimum 7.1°C, maximum 19.2°C), and in May, comfortable weather sets in with an average temperature of 18.1°C (minimum 12.9°C, maximum 23.4°C).

Spring and autumn are characterized by significant daily temperature fluctuations, often exceeding 10-12°C, which means cool mornings and evenings with warm daytime hours.

In Roanoke, precipitation is distributed quite evenly throughout the year, and there is no pronounced rainy season or prolonged dry period. The total amount of rainfall per month is small, usually ranging from 2 to 4 mm. This means the city is subject to neither heavy prolonged downpours nor extreme drought.

The nature of precipitation changes depending on the season. In winter, especially in January and December, when average minimum temperatures drop below freezing (about -1.8°C in January and 0.2°C in December), precipitation most often falls as snow. February can also bring snowfall. Rain prevails in the spring and autumn months. In summer, despite higher temperatures, the amount of precipitation remains moderate; for example, in July, the warmest month, only about 2 mm of precipitation falls on average, distributed over approximately 12 days.

If we consider the number of days with precipitation, May and August are the months with the highest number of such days – on average 13 days each. The fewest rainy days are observed in November (about 7 days) and October (about 8 days). In terms of total precipitation volume, a slight superiority is noted in February, May, and September (4 mm each), while July and November are considered the "driest" months with a figure of 2 mm. Overall, residents and guests of Roanoke can expect precipitation for approximately 9-12 days in most months of the year.

When planning a trip to Roanoke, it is important to consider its climate with four distinct seasons. Summer (June-August) is warm here, with an average temperature of about 22-25°C, and the maximum can reach almost 30°C. Light clothing is ideal for this time of year: T-shirts, shorts, dresses, as well as sunscreen, a hat, and sunglasses. Winters (December-February) in Roanoke are cool, with average temperatures from 2°C to 6°C and the possibility of frost. You will need warm clothes: sweaters, a jacket (possibly insulated and waterproof, as precipitation, although not abundant, does occur), a hat, gloves, and a scarf. Regardless of the season, comfortable walking shoes are a must-have, as there is plenty to see in the city.

Spring (March-May) and autumn (September-November) in Roanoke are characterized by changeable weather and moderate temperatures. Averages range from 8°C to 18°C in spring and from 8°C to 20°C in autumn. During these periods, it is best to apply the principle of layering clothes: T-shirts or long-sleeve shirts, light sweaters or fleece jackets, as well as a windbreaker or a mid-season jacket. Since the number of rainy days per month ranges from 7 to 13 throughout the year, despite the small total amount of precipitation, a light umbrella or raincoat will be a useful addition to your luggage at any time of year.

In general, for a comfortable trip to Roanoke, it is recommended to always have several layers of clothing with you to adapt to temperature changes throughout the day. Do not forget a personal first aid kit and an adapter for electrical appliances if necessary. Given the frequent, albeit not heavy precipitation, water-repellent outerwear or a compact umbrella will make your walks around the city more pleasant in any season.
