The city of Hagerstown features a temperate climate with four clearly defined seasons, offering tourists diverse weather conditions throughout the year. Summers here are warm and humid, with peak heat in July, when the average maximum temperature reaches 31°C. Winters, in turn, are cold, with average temperatures in January hovering around zero, and night-time frosts dropping below -2°C.

Spring and autumn serve as pleasant transitional periods. During these months, the weather in Hagerstown is mildest and most comfortable for walking and exploring the city. Temperatures rise gradually in spring and drop smoothly in autumn, creating ideal conditions for travel. A characteristic feature of the local climate is the relatively constant amount of precipitation throughout the year. Although the volume is not large, rainy or overcast days occur regularly, so it is worth carrying an umbrella or raincoat regardless of the season.

The climate in Hagerstown is distinguished by four distinct seasons, with a wide temperature range throughout the year. Summer here is warm and hot, while winter is cold and frosty. The hottest month is traditionally July, when the average temperature reaches 25.8°C, and daily highs regularly rise to 31°C. The coldest period falls in January, with an average temperature of about 1.3°C and night-time frosts, when the thermometer drops on average to -2.3°C.

The summer months — from June to August — are characterised by stable warm weather. Daytime air temperatures during this period range from 27°C to 31°C, creating classic conditions for a hot summer. Nights bring some relief but remain quite warm, with temperatures in the 17-21°C range. Winter, conversely, brings real cold. From December to February, daytime temperatures barely exceed zero, averaging 5-8°C, while freezing temperatures often occur at night.

Hagerstown's climate is also characterised by noticeable daily temperature fluctuations, especially in the spring and autumn months. The difference between day and night readings can reach 10 degrees or more. For example, in April, the average maximum is 17.7°C, while the minimum is just 6.9°C. This means that even after a warm sunny day, the evening can be quite cool, which is worth considering when planning walks.

In Hagerstown, precipitation is distributed quite evenly throughout the year, without a pronounced rainy or dry season. The total amount of precipitation remains consistently low throughout all months, so the key differences lie in the frequency of rainy days and the type of precipitation, which changes depending on the temperature.

The summer months, especially July and August, are the period with the highest frequency of precipitation — an average of 13 rainy days in each. Although rains are usually not heavy, they happen more often than in other seasons. Conversely, autumn can be considered the driest time of the year. In October and November, the number of days with precipitation drops to a minimum — just about 8 per month, which creates comfortable conditions for walking.

In winter, from December to February, the average temperature hovers around zero, and night-time frosts are a common occurrence. Consequently, precipitation during this period often falls as snow. On average, there are about 10-11 days with precipitation in the winter months, so travellers should be prepared for snowy or slushy weather.

When planning a trip to Hagerstown, it is important to consider the four clearly defined seasons that influence wardrobe choices. The key principle when packing is layering. Temperatures during the day can change noticeably, so the ability to easily add or remove a layer of clothing will make your stay comfortable. Regardless of the time of year, comfortable shoes for walking are mandatory. Considering that there are on average 10-13 days with precipitation per month, a compact umbrella or a light waterproof jacket will be a useful addition to your luggage.

For a summer visit (June-August), pack light clothing: T-shirts, shorts, dresses. Days can be quite hot, so do not forget sunscreen and a hat. Evenings can be cooler, so a light sweater or cardigan will come in handy for walks. In autumn (September-November), the weather gradually cools down. You will need jeans, long-sleeved shirts, and jumpers, and for late autumn — a medium-warmth jacket.

In winter (December-February), it is cold in Hagerstown, and temperatures often drop below zero. Be sure to bring a warm winter jacket, hat, gloves, and a scarf. Waterproof footwear will be an advantage in case of snow or wet weather. Spring (March-May) is a transitional period. In early spring, it is still cool and warm clothes may be needed, but by May the weather becomes significantly warmer, allowing for lighter clothing, though always with a jacket or windbreaker in case of cool wind or rain.
