Weather in Johnstown

Planning a trip or a stroll through the city of Johnstown? In this section, you will find up-to-date weather information, detailed forecasts, and clear charts to help you prepare for your journey.

The climate in Johnstown can be described as temperate, with four distinct seasons, allowing tourists to witness a classic change of natural scenery. Summers here are usually warm and comfortable, ideal for outdoor walks: in July and August, the air warms up to an average of +22°C...+27°C. Winters, by contrast, are cool and crisp, with average temperatures around zero and periodic frosts, especially in January and February.

An important feature of the local weather is the relatively high frequency of precipitation throughout the year. Statistics show that the number of "wet" days remains stable at 11–17 days per month, regardless of the season. This means that even in the warmest summer months or during the golden autumn, travellers should be prepared for short-term rains, so having an umbrella or raincoat in your luggage will be very useful.

The climate in Johnstown is characterised by distinct seasonality, offering travellers diverse weather conditions throughout the year. The coldest month is traditionally January, when the average temperature drops to -1.8°C. Winters here are truly frosty: night-time readings often dip into stable negatives, reaching an average of -5.5°C, whilst during the day the thermometer usually hovers around zero or rises slightly above. This time of year requires warm clothing and readiness for the cool air.

The summer season brings pleasant warmth to the region, making the city attractive for long walks and active leisure. The temperature peaks in July, when average readings are around 22.4°C. During the day, the air warms up to a comfortable 27.0°C, allowing you to enjoy summer without the exhausting heat typical of more southern states. August maintains this trend, remaining a warm and favourable month for tourism.

It is also worth noting the diurnal temperature variations, which are noticeable at any time of year. The difference between daily highs and nightly lows is usually between 5 and 10 degrees. Even at the height of summer, when days are sunny and warm, nights bring a refreshing coolness with temperatures around 17-18°C. Therefore, travellers are advised to bring light outerwear to feel comfortable after sunset.

In Johnstown, precipitation falls quite evenly throughout the year, so there is no distinct dry season. Travellers should be prepared for changeable weather and possible precipitation in almost any month, making an umbrella or raincoat useful companions for the trip.

The winter period is characterised by frequent precipitation amidst low temperatures. Given that in January and February average temperatures often drop below zero, rain frequently turns to snow. January stands out as the "wettest" month in terms of bad weather frequency: precipitation is recorded on average about 17 days a month, creating a typical winter atmosphere.

Spring and summer are also quite generous with rain, although its nature changes. In May and June, the number of days with precipitation remains high (about 15–16 days), but with the warming weather, it falls more often as refreshing rains or showers. Even at the height of summer, in July and August, rainy weather is not uncommon, occupying roughly half the month.

The most stable period can be considered the beginning and middle of autumn. September and October are statistically the "driest" months of the year. For instance, in October, the number of days with precipitation drops to 11, making this time particularly attractive for hiking and exploring the city.

The weather in Johnstown is distinguished by marked seasonality, so the contents of your suitcase will depend directly on your travel dates. In winter, when the temperature often stays around zero or drops lower, you will definitely need a warm jacket or down coat, a hat, a scarf, and gloves. In the transitional seasons — spring and autumn — the weather can be changeable, so it is best to stick to the principle of layering. Combine T-shirts, fleece jumpers, and windbreakers to easily adapt to temperature changes throughout the day.

Summer in the city is usually warm and pleasant, with daytime temperatures reaching 27°C, so light clothing made from natural fabrics will be very appropriate. However, statistics show that rain is a frequent occurrence here year-round (averaging 12–17 days with precipitation monthly). Regardless of the season, be sure to pack a reliable umbrella or a high-quality raincoat. In summer, this could be a light waterproof cape, and in the colder months, an insulated jacket with water-repellent treatment.

For walking around the city and sightseeing, choose comfortable shoes with flat soles that are comfortable for walking for long periods. Given the high probability of precipitation, it is desirable for footwear to be waterproof. Also, do not forget to bring sunglasses and sunscreen, especially if you are planning a trip between May and September when there are more sunshine hours.
