Weather in Louisville

Stay up to date with the latest weather conditions in Louisville. Below you will find current data, forecasts, and useful weather charts to help plan your time in the city.

Louisville, located in the USA, is characterized by a temperate continental climate. This means the city experiences four distinct seasons with noticeable temperature fluctuations throughout the year. Travelers should consider this feature when planning a trip, as the weather can differ significantly depending on the time of year.

Summer in Louisville is usually warm and sunny, and at times hot. Average temperatures in July, the warmest month, are around 25.9°C, with maximum values potentially rising above 30°C. Winters, conversely, are cool, with an average January temperature of around 2.2°C, and night frosts occur frequently when the temperature drops below freezing. Spring and autumn are transitional seasons, offering milder and more comfortable weather conditions that many find ideal for visiting the city.

Regarding precipitation, according to the provided data, it is distributed relatively evenly throughout most of the year. The average monthly precipitation is low, usually amounting to between 3 and 5 mm. The number of days with precipitation varies from approximately 8 to 14 per month. This suggests that although rain happens regularly, it is unlikely to be too prolonged or intense, allowing for outdoor activities to be planned with sufficient confidence.

The annual temperature progression in Louisville demonstrates distinct seasonality, characteristic of a temperate continental climate. The coldest month is January, when the average air temperature is just 2.2°C, and average nightly lows drop to -1.5°C. Conversely, the peak of summer heat falls in July, where the average temperature reaches 25.9°C, and average daily highs regularly rise to 30.5°C. Thus, the annual amplitude of average monthly temperatures is quite significant, which is important to consider when planning a trip.

Summer months in Louisville are a period of consistently warm, and at times hot, weather. Starting from June, when the average temperature is 23.8°C (with maximum values up to 28.7°C), the temperature continues to rise, reaching its peak in July (average 25.9°C, maximum 30.5°C). August also remains a very warm month with an average temperature of 24.7°C and maximum indicators up to 29.4°C. During this period, daytime temperatures often exceed the 25°C mark, and nights remain comfortably warm, with minimum temperatures in the 18-21°C range.

The winter season in Louisville is characterized by cool weather, especially in January, when the average temperature drops to 2.2°C, and nightly lows reach -1.5°C. December (average 5.1°C, maximum 9.1°C) and February (average 5.0°C, maximum 9.7°C) are also cold months, although somewhat milder than January. Night frosts during this period are not uncommon, and daytime temperatures usually range from close to freezing up to +10°C. It is worth noting that throughout the year in Louisville, noticeable daily temperature fluctuations are observed: the difference between daily highs and nightly lows is often between 7°C and 10°C. For example, in April, the difference between the average maximum (18.7°C) and minimum (8.1°C) temperature is 10.6°C, and in October – 9.8°C (20.8°C max, 11.0°C min), making evenings and nights perceptibly cooler even after warm days.

Precipitation in Louisville is distributed throughout the year, although in small amounts. According to the provided data, there is no distinct rainy season or dry period in terms of total precipitation volume, which remains low and varies from 3 to 5 mm per month. However, some monthly differences are observed both in the amount of rainfall and in the number of days with it.

The greatest amount of precipitation, an average of 5 mm, falls in February. At the same time, May is characterized by the highest number of days with precipitation — about 14 days. The least amount of precipitation (3 mm each) falls in the period from August to December. September stands out as the month with the fewest days with precipitation, averaging just 8. Given such small volumes, precipitation is likely to be in the form of light rain or drizzle. In winter months, such as January (with an average temperature of 2.2°C and a minimum of -1.5°C) and December (average 5.1°C, minimum 1.2°C), snowfall is also possible at sub-zero temperatures, although the provided data does not specify the type of precipitation.

Despite the small total amount, precipitation in Louisville occurs quite regularly throughout the year. The number of "wet" days varies from 8 in September to 14 in May. This means that on average, rain or other types of precipitation can be expected approximately every 2-4 days, depending on the specific month. Travelers planning a visit to Louisville should take this into account and perhaps carry an umbrella or a light waterproof jacket, especially if the trip falls during the spring months when the number of days with precipitation reaches its peak.

When planning a trip to Louisville, it is important to consider its four distinct seasons and corresponding weather changes. A key principle when packing your suitcase should be layering your clothes, as daily temperature fluctuations can be perceptible. Regardless of the time of year, comfortable walking shoes are your best friend, as there is much to see in the city. Given that precipitation, while not heavy, happens regularly (from 8 to 14 days a month), a light umbrella or waterproof jacket will be a useful addition to your luggage.

If your visit falls during the summer months (June-August), when the average temperature ranges from 23.8°C to 25.9°C, and the maximum can exceed 30°C, pack light, breathable clothing: t-shirts, shorts, sundresses. Don't forget sunscreen, a hat, and sunglasses. Evenings can be slightly cooler, so a light sweater or cardigan will come in handy. For a winter trip (December-February), when average temperatures drop to 2.2°C - 5.1°C, and nightly lows can be below freezing, warm items are necessary: sweaters, fleece jackets, a warm coat (possibly windproof and waterproof), a hat, gloves, and a scarf. Warm, waterproof footwear will also be appropriate.

Spring (March-May) and autumn (September-November) in Louisville are transitional seasons with changeable weather. In spring, the temperature gradually rises from an average of 9.2°C in March to 19.9°C in May. In autumn, conversely, a gradual cooling occurs: from a warm 22.2°C in September to a cool 8.6°C in November. For these seasons, the principle of layering is ideal: t-shirts, long-sleeved shirts, jumpers, and a light or mid-season jacket. May has the most days with precipitation, and September has the fewest, but an umbrella or light raincoat will not be amiss in any of these months.
