Planning a visit to Marshalltown? Here you will find the latest information on weather conditions, including current forecasts and clear charts to help you prepare for your trip.

The climate in Marshalltown can be described as humid continental, which is typical for this region of the United States. All four seasons are clearly defined, so the weather changes significantly from season to season. Travelers should expect notable contrasts: from freezing winter months to truly warm and sunny summer days.

Summers in the city are generally warm and favorable for tourism, with average high temperatures reaching 28°C in June and July. This is the best time to visit parks and enjoy outdoor activities. Winters here are harsh and snowy; in January and February, the thermometer consistently stays below freezing, and night temperatures can drop to -10°C.

The transitional seasons—spring and autumn—offer milder conditions, although spring, especially May, can be quite rainy: this period records the highest number of days with precipitation. September often delights with mild weather, retaining summer warmth, but by November, the air cools down significantly, preparing the city for winter.

Temperature patterns in Marshalltown are characterized by distinct seasonality, offering tourists a wide range of weather conditions depending on the time of year. The coldest month is traditionally January, with an average temperature of about -6.1°C and night frosts down to -10°C. In contrast to winter, mid-summer brings the peak of warmth: July is considered the hottest period, when average figures reach 23.8°C and daytime air warms up to nearly 29°C.

Summers in the city are generally warm and favorable for outdoor activities. From June to August, daytime temperatures stay consistently in the range of 27–29°C, creating a true summer atmosphere without extreme heat. However, daily fluctuations should be considered: a warm day is followed by pleasant nightly freshness, when the thermometer drops to 17–19°C. September continues to delight with mild warmth, often keeping daytime highs at a comfortable 25°C.

The winter period here is truly freezing. From December to February, average temperatures remain below zero, and the landscapes take on a classic winter look. February, like January, has a harsh character with lows around -9.5°C. Spring arrives gradually: while March can still be cool (averaging +4°C), by May, very pleasant weather sets in with daytime highs above 22°C, marking the start of the tourist season.

In Marshalltown, precipitation patterns change significantly depending on the time of year, which is directly linked to seasonal temperature fluctuations. In winter, from December to February, when average temperatures drop below freezing (as low as -6.1°C in January), precipitation most often falls as snow. This is the period with the least moisture: February and December record the lowest precipitation volumes, with inclement weather observed on average only 6–8 days per month.

With the arrival of spring, the situation changes and precipitation begins to increase. The wettest month of the year is May: this time sees the highest precipitation volume (5 mm) and a record number of rainy days—about 14. Summer also remains a relatively wet period, especially June, when it rains about 11 days a month. During the warm season, precipitation usually occurs as showers or short rains.

In autumn, the frequency of precipitation remains moderate, but by the end of the season, the weather becomes drier. About 10 days of precipitation can still be expected in October, but by November, this number drops to 6 days. Travelers planning a trip to Marshalltown should keep in mind that the rainiest period is late spring and early summer, while winter, though cold, is relatively dry.

Since Marshalltown has distinct seasons, what you pack will depend directly on the time of year. Winters here are freezing, with temperatures in January and February often dropping well below zero, so be sure to bring a warm, windproof jacket or down coat, as well as a hat, scarf, and gloves. Thermal underwear is an excellent choice for comfortable city walks during the cold months.

Summer, by contrast, is pleasantly warm: in June and July, the air warms up to an average of +28°C. For a trip during this season, choose light clothing made of natural breathable fabrics like cotton or linen. Don't forget to pack sunglasses, SPF sunscreen, and a hat to protect yourself from the midday sun. Comfortable walking shoes are a must any time of year, as you will likely want to explore on foot.

Spring and autumn in this region can be changeable, so travelers should follow the principle of layering. A combination of a T-shirt, a fleece, and a light windbreaker will allow you to quickly adapt to weather changes throughout the day. Note that May is one of the rainiest months, so a compact umbrella or a high-quality raincoat will come in very handy if you are planning a spring trip.
